+version locale dans le fichier @file{CODE-OF-CONDUCT} dans l'arborescence
+des sources.
+
+Les contributeurs n'ont pas besoin d'utiliser leur nom légal dans leurs
+correctifs et leurs communications en ligne ; ils peuvent utiliser n'importe

+@section Construire depuis Git
+
+Si vous souhaitez travailler sur Guix lui-même, il est recommandé d'utiliser
+la dernière version du dépôt Git :
+
+@example
+git clone https://git.savannah.gnu.org/git/guix.git
+@end example
+
+Lors de la construction de Guix depuis un extrait, les paquets suivants sont
+requis en plus de ceux mentionnés dans les instructions d'installation
+(@pxref{Prérequis}).
+
+@itemize
+@item @url{http://gnu.org/software/autoconf/, GNU Autoconf};
+@item @url{http://gnu.org/software/automake/, GNU Automake};
+@item @url{http://gnu.org/software/gettext/, GNU Gettext};
+@item @url{http://gnu.org/software/texinfo/, GNU Texinfo};
+@item @url{http://www.graphviz.org/, Graphviz};
+@item @url{http://www.gnu.org/software/help2man/, GNU Help2man (facultatif)}.
+@end itemize
+
+La manière la plus simple de configurer un environnement de développement
+pour Guix est, bien sûr, d'utiliser Guix ! La commande suivante démarre un
+nouveau shell où toutes les dépendances et les variables d'environnements
+appropriées sont configurés pour travailler sur Guix :
+
+@example
+guix environment guix
+@end example
+
+@xref{Invoquer guix environment}, pour plus d'information sur cette
+commande. On peut ajouter des dépendances supplémentaires avec
+@option{--ad-hoc} :
+
+@example
+guix environment guix --ad-hoc help2man git strace
+@end example
+
+Lancez @command{./bootstrap} pour générer l'infrastructure du système de
+construction avec Autoconf et Automake. Si vous avez une erreur comme :
+
+@example
+configure.ac:46: error: possibly undefined macro: PKG_CHECK_MODULES
+@end example
+
+@noindent
+cela signifie probablement qu'Autoconf n'a pas pu trouver @file{pkg.m4} qui
+est fournit par pkg-config. Assurez-vous que @file{pkg.m4} est
+disponible. C'est aussi vrai pour l'ensemble de macros de @file{guile.m4}
+fournies par Guile. Par exemple, si vous avez installé Automake dans
+@file{/usr/local}, il ne cherchera pas les fichiers @file{.m4} dans
+@file{/usr/share}. Dans ce case vous devez invoquer la commande suivante :
+
+@example
+export ACLOCAL_PATH=/usr/share/aclocal
+@end example
+
+@xref{Macro Search Path,,, automake, The GNU Automake Manual}, pour plus
+d'information.
+
+Ensuite, lancez @command{./configure} comme d'habitude. Assurez-vous de
+passer @code{--localstatedir=@var{directory}} où @var{directory} est la
+valeur @code{localstatedir} utilisée par votre installation actuelle
+(@pxref{Le dépôt} pour plus d'informations à ce propos).
+
+Finalement, vous devez invoquer @code{make check} pour lancer les tests
+(@pxref{Lancer la suite de tests}). Si quelque chose échoue, jetez un œil
+aux instructions d'installation (@pxref{Installation}) ou envoyez un message
+à la list @email{guix-devel@@gnu.org}.
+
+
+@node Lancer Guix avant qu'il ne soit installé
+@section Lancer Guix avant qu'il ne soit installé
+
+Pour garder un environnement de travail sain, il est utile de tester les
+changement localement sans les installer pour de vrai. Pour pouvoir
+distinguer votre rôle « d'utilisateur final » de celui parfois haut en
+couleur de « développeur ».
+
+Pour cela, tous les outils en ligne de commande sont utilisables même sans
+avoir lancé @code{make install}. Vous devez pour cela préfixer chaque
+commande par @command{./pre-inst-env} (le script @file{pre-inst-env} se
+trouve dans le répertoire de plus haut niveau de l'arborescence des sources
+de Guix) comme cela@footnote{L'option @option{-E} de @command{sudo} garantie
+que @code{GUILE_LOAD_PATH} est bien paramétré pour @command{guix-daemon} et
+les outils qu'il utilise puissent trouver les modules Guile dont ils ont
+besoin.} :
+
+@example
+$ sudo -E ./pre-inst-env guix-daemon --build-users-group=guixbuild
+$ ./pre-inst-env guix build hello
+@end example
+
+@noindent
+De même, pour une session Guile qui utilise les modules Guix :
+
+@example
+$ ./pre-inst-env guile -c '(use-modules (guix utils)) (pk (%current-system))'
+
+;;; ("x86_64-linux")
+@end example
+
+@noindent
+@cindex REPL
+@cindex read-eval-print loop
+@dots{} et pour un REPL (@pxref{Using Guile Interactively,,, guile, Guile
+Reference Manual})
+
+@example
+$ ./pre-inst-env guile
+scheme@@(guile-user)> ,use(guix)
+scheme@@(guile-user)> ,use(gnu)
+scheme@@(guile-user)> (define snakes
+                       (fold-packages
+                         (lambda (package lst)
+                           (if (string-prefix? "python"
+                                               (package-name package))
+                               (cons package lst)
+                               lst))
+                         '()))
+scheme@@(guile-user)> (length snakes)
+$1 = 361
+@end example
+
+Le script @command{pre-inst-env} paramètre toutes les variables
+d'environnement nécessaires, dont @env{PATH} et @env{GUILE_LOAD_PATH}.
+
+Remarquez que @command{./pre-inst-env guix pull} ne met @emph{pas} à jour
+l'arborescence des sources locale ; il met seulement à jour le lien
+symbolique @file{~/.config/guix/latest} (@pxref{Invoquer guix pull}). Lancez
+@command{git pull} à la place si vous voulez mettre à jour votre
+arborescence des sources locale@footnote{Si vous voulez paramétrer
+@command{guix} pour qu'il utilise votre dépôt Git, vous pouvez faire pointer
+le lien symbolique @file{~/.config/guix/latest} vers le répertoire contenant
+ce dépôt. Si vous le seul utilisateur du système, vous pouvez aussi
+considérer faire pointer le lien symbolique @file{/root/.config/guix/latest}
+vers @file{~/.config/guix/latest} ; comme ça root aura toujours la même
+commande @command{guix} que votre utilisateur}.

+@node La configuration parfaite
+@section La configuration parfaite
+
+La configuration parfaite pour travailler sur Guix est simplement la
+configuration parfaite pour travailler en Guile (@pxref{Using Guile in
+Emacs,,, guile, Guile Reference Manual}). Tout d'abord, vous avez besoin de
+mieux qu'un éditeur de texte, vous avez besoin de
+@url{http://www.gnu.org/software/emacs, Emacs}, amélioré par le superbe
+@url{http://nongnu.org/geiser/, Geiser}.
+
+Geiser permet le développement interactif et incrémental depuis Emacs : la
+compilation du code et son évaluation depuis les buffers, l'accès à la
+documentation en ligne (docstrings), la complétion sensible au contexte,
+@kbd{M-.} pour sauter à la définition d'un objet, un REPL pour tester votre
+code, et bien plus (@pxref{Introduction,,, geiser, Geiser User
+Manual}). Pour travailler confortablement sur Guix, assurez-vous de modifier
+le chemin de chargement de Guile pour qu'il trouve les fichiers source de
+votre dépôt :
+
+@lisp
+;; @r{Si l'extrait est dans ~/src/guix.}
+(with-eval-after-load 'geiser-guile
+  (add-to-list 'geiser-guile-load-path "~/src/guix"))
+@end lisp
+
+To actually edit the code, Emacs already has a neat Scheme mode.  But in
+addition to that, you must not miss
+@url{http://www.emacswiki.org/emacs/ParEdit, Paredit}.  It provides
+facilities to directly operate on the syntax tree, such as raising an
+s-expression or wrapping it, swallowing or rejecting the following
+s-expression, etc.
+
+@cindex extraits de code
+@cindex modèles
+@cindex réduire la quantité de code commun
+Nous fournissons aussi des modèles pour les messages de commit git communs
+et les définitions de paquets dans le répertoire @file{etc/snippets}. Ces
+modèles s'utilisent avec @url{http://joaotavora.github.io/yasnippet/,
+YASnippet} pour développer des chaînes courtes de déclenchement en extraits
+de texte interactifs. Vous pouvez ajouter le répertoire des modèles dans la
+variables @var{yas-snippet-dirs} d'Emacs.
+
+@lisp
+;; @r{Si l'extrait est dans ~/src/guix.}
+(with-eval-after-load 'yasnippet
+  (add-to-list 'yas-snippet-dirs "~/src/guix/etc/snippets"))
+@end lisp
+
+Les extraits de messages de commit dépendent de @url{https://magit.vc/,
+Magit} pour afficher les fichiers sélectionnés. Lors de la modification d'un
+message de commit, tapez @code{add} suivi de @kbd{TAB} pour insérer un
+modèle de message de commit pour ajouter un paquet ; tapez @code{update}
+suivi de @kbd{TAB} pour insérer un modèle pour la mise à jour d'un paquet.
+
+L'extrait principal pour @code{scheme-mode} est lancé en tapant
+@code{package…} suivi par @kbd{TAB}. Cet extrait insère aussi la chaîne de
+déclenchement @code{origin…}, qui peut aussi être étendue. L'extrait
+@code{origin} lui-même peut aussi insérer des chaînes de déclenchement qui
+finissent sur @code{…}, qui peuvent aussi être étendues.
+
+
+@node Style de code
+@section Style de code
+
+En général notre code suit le Standard de Code GNU (@pxref{Top,,, standards,
+GNU Coding Standards}). Cependant, il ne parle pas beaucoup de Scheme, donc
+voici quelques règles supplémentaires.
+
+@menu
+* Paradigme de programmation::  Comment composer vos éléments.
+* Modules::                  Où stocker votre code ?
+* Types de données et reconnaissance de motif::  Implémenter des

+* Formatage du code::        Conventions d'écriture.
+@end menu
+
+@node Paradigme de programmation
+@subsection Paradigme de programmation
+
+Le code Scheme dans Guix est écrit dans un style purement fonctionnel. Le
+code qui s'occupe des entrées-sorties est une exception ainsi que les
+procédures qui implémentent des concepts bas-niveau comme la procédure
+@code{memoize}.
+
+@node Modules
+@subsection Modules
+
+Les modules Guile qui sont sensés être utilisés du côté de la construction
+doivent se trouver dans l'espace de nom @code{(guix build @dots{})}. Ils ne
+doivent pas se référer à d'autres modules Guix ou GNU. Cependant il est
+correct pour un module « côté hôte » de dépendre d'un module coté
+construction.
+
+Les modules qui s'occupent du système GNU général devraient se trouver dans
+l'espace de nom @code{(gnu @dots{})} plutôt que @code{(guix @dots{})}.
+
+@node Types de données et reconnaissance de motif
+@subsection Types de données et reconnaissance de motif
+
+La tendance en Lisp classique est d'utiliser des listes pour tout
+représenter et de naviguer dedans « à la main ( avec @code{car}, @code{cdr},
+@code{cadr} et compagnie. Il y a plusieurs problèmes avec ce style,
+notamment le fait qu'il soit dur à lire, source d'erreur et un obstacle aux
+rapports d'erreur bien typés.
+
+Le code de Guix devrait définir des types de données appropriées (par
+exemple, avec @code{define-record-type*}) plutôt que d'abuser des listes. En
+plus, il devrait utiliser la recherche de motifs, via le module Guile
+@code{(ice-9 match)}, surtout pour rechercher dans des listes.
+
+@node Formatage du code
+@subsection Formatage du code
+
+@cindex formater le code
+@cindex style de code
+Lorsque nous écrivons du code Scheme, nous suivons la sagesse commune aux
+programmeurs Scheme. En général, nous suivons les
+@url{http://mumble.net/~campbell/scheme/style.txt, règles de style de
+Riastradh}. Ce document décrit aussi les conventions utilisées dans le code
+de Guile. Il est bien pensé et bien écrit, alors n'hésitez pas à le lire.
+
+Certaines formes spéciales introduites dans Guix comme la macro
+@code{substitute*} ont des règles d'indentation spécifiques. Elles sont
+définies dans le fichier @file{.dir-locals.el} qu'Emacs utilise
+automatiquement. Remarquez aussi qu'Emacs-Guix fournit le mode
+@code{guix-devel-mode} qui indente et colore le code Guix correctement
+(@pxref{Development,,, emacs-guix, The Emacs-Guix Reference Manual}).
+
+@cindex indentation, du code
+@cindex formatage, du code
+Si vous n'utilisez pas Emacs, assurez-vous que votre éditeur connaisse ces
+règles. Pour indenter automatiquement une définition de paquet, vous pouvez
+aussi lancer :
+
+@example
+./etc/indent-code.el gnu/packages/@var{file}.scm @var{package}
+@end example
+
+@noindent
+Cela indente automatiquement la définition de @var{package} dans
+@file{gnu/packages/@var{file}.scm} en lançant Emacs en mode commande. Pour
+indenter un fichier complet, n'indiquez pas de second argument :
+
+@example
+./etc/indent-code.el gnu/services/@var{file}.scm
+@end example
+
+Nous demandons que toutes les procédure de premier niveau contiennent une
+chaîne de documentation. Ce pré-requis peut être relâché pour les procédures
+privées simples dans l'espace de nom @code{(guix build @dots{})} cependant.
+
+Les procédures ne devraient pas avoir plus de quatre paramètres
+positionnés. Utilisez des paramètres par mot-clefs pour les procédures qui
+prennent plus de quatre paramètres.
+

+@node Envoyer des correctifs
+@section Envoyer des correctifs
+
+Le développement se fait avec le système de contrôle de version Git. Ainsi,
+l'accès au dépôt n'est pas strictement nécessaire. Nous accueillons les
+contributions sous forme de correctifs produits par @code{git format-patch}
+envoyés sur la liste de diffusion @email{guix-patches@@gnu.org}.
+
+Cette liste de diffusion est gérée par une instance Debbugs accessible à
+l'adresse @uref{https://bugs.gnu.org/guix-patches}, qui nous permet de
+suivre les soumissions. Chaque message envoyé à cette liste se voit
+attribuer un numéro de suivi ; les gens peuvent ensuite répondre à cette
+soumission en envoyant un courriel à @code{@var{NNN}@@debbugs.gnu.org}, où
+@var{NNN} est le numéro de suivi (@pxref{Envoyer une série de correctifs}).
+
+Veuillez écrire les messages de commit dans le format ChangeLog
+(@pxref{Change Logs,,, standards, GNU Coding Standards}) ; vous pouvez
+regarder l'historique des commits pour trouver des exemples.
+
+Avant de soumettre un correctif qui ajoute ou modifie la définition d'un
+paquet, veuillez vérifier cette check-list :
+
+@enumerate
+@item
+Si les auteurs du paquet logiciel fournissent une signature cryptographique
+pour l'archive, faîtes un effort pour vérifier l'authenticité de
+l'archive. Pour un fichier de signature GPG détaché, cela se fait avec la
+commande @code{gpg --verify}.
+
+@item
+Prenez un peu de temps pour fournir un synopsis et une description adéquats
+pour le paquet. Voir @xref{Synopsis et descriptions} pour quelques lignes
+directrices.
+
+@item
+Lancez @code{guix lint @var{paquet}}, où @var{paquet} est le nom du nouveau
+paquet ou du paquet modifié, et corrigez les erreurs qu'il rapporte
+(@pxref{Invoquer guix lint}).
+
+@item
+Assurez-vous que le paquet se construise sur votre plate-forme avec
+@code{guix build @var{paquet}}.
+
+@item
+@cindex construction groupée
+Assurez-vous que le paquet n'utilise pas de copie groupée d'un logiciel déjà
+disponible dans un paquet séparé.
+
+Parfois, les paquets incluent des copie du code source de leurs dépendances
+pour le confort de leurs utilisateurs. Cependant, en tant que distribution,
+nous voulons nous assurer que ces paquets utilisent bien les copient que
+nous avons déjà dans la distribution si elles existent. Cela améliore
+l'utilisation des ressources (la dépendance n'est construite et stockée
+qu'une seule fois) et permet à la distribution de faire des changements
+transversaux comme appliquer des correctifs de sécurité pour un paquet donné
+depuis un unique emplacement et qu'ils affectent tout le système, ce
+qu'empêchent les copies groupées.
+
+@item
+Regardez le profile rapporté par @command{guix size} (@pxref{Invoquer guix size}). Cela vous permettra de remarquer des références à d'autres paquets
+qui ont été retenus. Il peut aussi aider à déterminer s'il faut découper le
+paquet (@pxref{Des paquets avec plusieurs résultats}) et quelle dépendance
+facultative utiliser.
+
+@item
+Pour les changements important, vérifiez que les paquets qui en dépendent
+(s'ils existent) ne sont pas affectés par le changement ; @code{guix refresh
+--list-dependant @var{paquet}} vous aidera (@pxref{Invoquer guix refresh}).

+@cindex stratégie de branche
+@cindex stratégie de planification des reconstructions
+Suivant le nombre de paquets dépendants et donc le nombre de reconstruction
+induites, les commits vont vers des branches différentes, suivant ces
+principes :
+
+@table @asis
+@item 300 paquets dépendants ou moins
+branche @code{master} (changements non-disruptifs).
+
+@item entre 300 et 1 200 paquets dépendants
+branche @code{staging} (changemets non-disruptifs). Cette branche devrait
+être fusionnées dans @code{master} tous les 3 semaines. Les changements par
+thèmes (par exemple une mise à jour de la pile GNOME) peuvent aller dans une
+branche spécifique (disons, @code{gnome-updates}).
+
+@item plus de 1 200 paquets dépendants
+branche @code{core-updates} (peut inclure des changements majeurs et
+potentiellement disruptifs). Cette branche devrait être fusionnée dans
+@code{master} tous les 2,5 mois environ.
+@end table
+
+Toutes ces branches sont gérées par notre ferme de construction et
+fusionnées dans @code{master} une fois que tout a été construit
+correctement. Cela nous permet de corriger des problèmes avant qu'ils
+n'atteignent les utilisateurs et réduit la fenêtre pendant laquelle les
+binaires pré-construits ne sont pas disponibles.
+
+@item
+@cindex déterminisme, du processus de construction
+@cindex construction reproductibles, vérification
+Vérifiez si le processus de construction du paquet est déterministe. Cela
+signifie typiquement vérifier qu'une construction indépendante du paquet
+renvoie exactement le même résultat que vous avez obtenu, bit à bit.
+
+Une manière simple de le faire est de reconstruire le paquet plusieurs fois
+à la suite sur votre machine (@pxref{Invoquer guix build}) :
+
+@example
+guix build --rounds=2 mon-paquet
+@end example
+
+Cela est suffisant pour trouver une classe de non-déterminisme commune,
+comme l'horodatage ou des sorties générées aléatoirement dans le résultat de
+la construction.
+
+Une autre option consiste à utiliser @command{guix challenge}
+(@pxref{Invoquer guix challenge}). Vous pouvez lancer la commande une fois
+que les paquets ont été commités et construits par @code{hydra.gnu.org} pour
+vérifier s'il obtient le même résultat que vous. Mieux encore : trouvez une
+autre machine qui peut le construire et lancez @command{guix publish}. Puis
+la machine distante est sûrement différente de la vôtre, cela peut trouver
+des problèmes de non-déterminisme liés au matériel — par exemple utiliser
+une extension du jeu d'instruction — ou du noyau du système d'exploitation —
+par exemple se reposer sur @code{uname} ou les fichiers de @file{/proc}.
+
+@item
+Lorsque vous écrivez de la documentation, utilisez une formulation au genre
+neutre lorsque vous vous référez à des personnes, comme le
+@uref{https://fr.wikipedia.org/wiki/They_singulier, ``they''@comma{}
+``their''@comma{} ``them'' singulier} (en anglais).
+
+@item
+Vérifiez que votre correctif contienne seulement un ensemble de changements
+liés. Grouper des changements non liés ensemble rend la revue plus difficile
+et plus lente.
+
+Ajouter plusieurs paquet ou une mise à jour d'un paquet avec des corrections
+dans ce paquet sont des exemples de changements sans rapport.
+
+@item
+Suivez nos règles de formatage de code, éventuellement en lançant le script
+@command{et/indent-code.el} pour le faire automatiquement (@pxref{Formatage
+du code}).
+
+@end enumerate

+@node Introduction
+@chapter Introduction
+
+@cindex but
+GNU Guix@footnote{« Guix » se prononce comme « geeks » (en prononçant le
+« s »), ou « ɡiːks » dans l'alphabet phonétique international (API).} est un
+outil de gestion de paquets pour le système GNU. Guix facilite pour les
+utilisateurs non privilégiés l'installation, la mise à jour et la
+suppression de paquets, la restauration à un ensemble de paquets précédent,
+la construction de paquets depuis les sources et plus généralement aide à la
+création et à la maintenance d'environnements logiciels.
+
+@cindex interfaces utilisateurs
+Guix fournit une interface de gestion des paquets par la ligne de commande
+(@pxref{Invoquer guix package}), un ensemble d'utilitaires en ligne de
+commande (@pxref{Utilitaires}) ainsi que des interfaces de programmation
+Scheme (@pxref{Interface de programmation}).
+@cindex démon de construction
+Son @dfn{démon de construction} est responsable de la construction des
+paquets pour les utilisateurs (@pxref{Paramétrer le démon}) et du
+téléchargement des binaires pré-construits depuis les sources autorisées
+(@pxref{Substituts}).
+
+@cindex extensibilité de la distribution
+@cindex personnalisation, des paquets
+Guix contient de nombreuses définitions de paquet GNU et non-GNU qui
+respectent tous les @uref{https://www.gnu.org/philosophy/free-sw.fr.html,
+libertés de l'utilisateur}. Il est @emph{extensible} : les utilisateurs
+peuvent écrire leurs propres définitions de paquets (@pxref{Définition des paquets}) et les rendre disponibles dans des modules de paquets
+indépendants (@pxref{Modules de paquets}). Il est aussi
+@emph{personnalisable} : les utilisateurs peuvent @emph{dériver} des
+définitions de paquets spécialisées à partir de définitions existantes, même
+depuis la ligne de commande (@pxref{Options de transformation de paquets}).
+
+@cindex Distribution Système Guix
+@cindex GuixSD
+Vous pouvez installer GNU@tie{}Guix sur un système GNU/Linux existant pour
+compléter les outils disponibles sans interférence (@pxref{Installation}) ou
+vous pouvez l'utiliser à travers la @dfn{Distribution Système Guix} ou
+GuixSD (@pxref{Distribution GNU}) distincte. Avec GNU@tie{}GuixSD, vous
+@emph{déclarez} tous les aspects de la configuration du système
+d'exploitation et Guix s'occupe de créer la configuration d'une manière
+transactionnelle, reproductible et sans état (@pxref{Configuration
+système}).
+
+@cindex gestion de paquet fonctionnelle
+Sous le capot, Guix implémente la discipline de @dfn{gestion de paquet
+fonctionnel} inventé par Nix (@pxref{Remerciements}). Dans Guix le processus
+de construction et d'installation des paquets est vu comme une
+@emph{fonction} dans le sens mathématique du terme. Cette fonction a des
+entrées (comme des scripts de construction, un compilateur et des
+bibliothèques) et renvoie un paquet installé. En tant que fonction pure, son
+résultat ne dépend que de ses entrées. Par exemple, il ne peut pas faire
+référence à des logiciels ou des scripts qui n'ont pas été explicitement
+passés en entrée. Une fonction de construction produit toujours le même
+résultat quand on lui donne le même ensemble d'entrée. Elle ne peut pas
+modifier l'environnement du système en cours d'exécution d'aucune manière ;
+par exemple elle ne peut pas créer, modifier ou supprimer des fichiers en
+dehors de ses répertoires de construction et d'installation. Ce résultat
+s'obtient en lançant les processus de construction dans des environnements
+isolés (ou des @dfn{conteneurs}) où seules les entrées explicites sont
+visibles.
+
+@cindex dépôt
+Le résultat des fonctions de construction de paquets est mis en @dfn{cache}
+dans le système de fichier, dans répertoire spécial appelé le @dfn{dépôt}
+(@pxref{Le dépôt}). Chaque paquet est installé dans son répertoire propre
+dans le dépôt — par défaut dans @file{/gnu/store}. Le nom du répertoire
+contient un hash de toutes les entrées utilisées pour construire le paquet ;
+ainsi, changer une entrée donnera un nom de répertoire différent.
+
+Cette approche est le fondement des fonctionnalités les plus importante de
+Guix : le support des mises à jour des paquets et des retours en arrière
+transactionnels, l'installation différenciée par utilisateur et le ramassage
+de miettes pour les paquets (@pxref{Fonctionnalités}).

+
+@cindex installing Guix from binaries
+This section describes how to install Guix on an arbitrary system from a
+self-contained tarball providing binaries for Guix and for all its
+dependencies.  This is often quicker than installing from source, which is
+described in the next sections.  The only requirement is to have
+GNU@tie{}tar and Xz.
+
+We provide a
+@uref{https://git.savannah.gnu.org/cgit/guix.git/plain/etc/guix-install.sh,
+shell installer script}, which automates the download, installation, and
+initial configuration of Guix.  It should be run as the root user.
+
+Installing goes along these lines:
+
+@enumerate
+@item
+@cindex downloading Guix binary
+Download the binary tarball from
+@indicateurl{ftp://alpha.gnu.org/gnu/guix/guix-binary-@value{VERSION}.@var{system}.tar.xz},
+where @var{system} is @code{x86_64-linux} for an @code{x86_64} machine
+already running the kernel Linux, and so on.
+
+@c The following is somewhat duplicated in ``System Installation''.
+Make sure to download the associated @file{.sig} file and to verify the
+authenticity of the tarball against it, along these lines:
+
+@example
+$ wget ftp://alpha.gnu.org/gnu/guix/guix-binary-@value{VERSION}.@var{system}.tar.xz.sig
+$ gpg --verify guix-binary-@value{VERSION}.@var{system}.tar.xz.sig
+@end example
+
+If that command fails because you do not have the required public key, then
+run this command to import it:
+
+@example
+$ gpg --keyserver pgp.mit.edu --recv-keys @value{OPENPGP-SIGNING-KEY-ID}
+@end example
+
+@noindent
+@c end authentication part
+and rerun the @code{gpg --verify} command.
+
+@item
+Now, you need to become the @code{root} user.  Depending on your
+distribution, you may have to run @code{su -} or @code{sudo -i}.  As
+@code{root}, run:
+
+@example
+# cd /tmp
+# tar --warning=no-timestamp -xf \
+     guix-binary-@value{VERSION}.@var{system}.tar.xz
+# mv var/guix /var/ && mv gnu /
+@end example
+
+This creates @file{/gnu/store} (@pxref{Le dépôt}) and @file{/var/guix}.
+The latter contains a ready-to-use profile for @code{root} (see next step.)
+
+Do @emph{not} unpack the tarball on a working Guix system since that would
+overwrite its own essential files.
+
+The @code{--warning=no-timestamp} option makes sure GNU@tie{}tar does not
+emit warnings about ``implausibly old time stamps'' (such warnings were
+triggered by GNU@tie{}tar 1.26 and older; recent versions are fine.)  They
+stem from the fact that all the files in the archive have their modification
+time set to zero (which means January 1st, 1970.)  This is done on purpose
+to make sure the archive content is independent of its creation time, thus
+making it reproducible.
+
+@item
+Make @code{root}'s profile available under @file{~root/.guix-profile}:
+
+@example
+# ln -sf /var/guix/profiles/per-user/root/guix-profile \
+         ~root/.guix-profile
+@end example
+
+Source @file{etc/profile} to augment @code{PATH} and other relevant
+environment variables:
+
+@example
+# GUIX_PROFILE="`echo ~root`/.guix-profile" ; \
+  source $GUIX_PROFILE/etc/profile
+@end example
+
+@item
+Create the group and user accounts for build users as explained below
+(@pxref{Réglages de l'environnement de construction}).
+
+@item
+Run the daemon, and set it to automatically start on boot.
+
+If your host distro uses the systemd init system, this can be achieved with
+these commands:
+
+@c Versions of systemd that supported symlinked service files are not
+@c yet widely deployed, so we should suggest that users copy the service
+@c files into place.
+@c
+@c See this thread for more information:
+@c http://lists.gnu.org/archive/html/guix-devel/2017-01/msg01199.html
+
+@example
+# cp ~root/.guix-profile/lib/systemd/system/guix-daemon.service \
+        /etc/systemd/system/
+# systemctl start guix-daemon && systemctl enable guix-daemon
+@end example
+
+If your host distro uses the Upstart init system:
+
+@example
+# initctl reload-configuration
+# cp ~root/.guix-profile/lib/upstart/system/guix-daemon.conf /etc/init/
+# start guix-daemon
+@end example
+
+Otherwise, you can still start the daemon manually with:
+
+@example
+# ~root/.guix-profile/bin/guix-daemon --build-users-group=guixbuild
+@end example
+
+@item
+Make the @command{guix} command available to other users on the machine, for
+instance with:
+
+@example
+# mkdir -p /usr/local/bin
+# cd /usr/local/bin
+# ln -s /var/guix/profiles/per-user/root/guix-profile/bin/guix
+@end example
+
+It is also a good idea to make the Info version of this manual available
+there:
+
+@example
+# mkdir -p /usr/local/share/info
+# cd /usr/local/share/info
+# for i in /var/guix/profiles/per-user/root/guix-profile/share/info/* ;
+  do ln -s $i ; done
+@end example
+
+That way, assuming @file{/usr/local/share/info} is in the search path,
+running @command{info guix} will open this manual (@pxref{Other Info
+Directories,,, texinfo, GNU Texinfo}, for more details on changing the Info
+search path.)
+
+@item
+@cindex substitutes, authorization thereof
+Pour utiliser les substituts de @code{hydra.gnu.org} ou l'un de ses mirroirs
+(@pxref{Substituts}), autorisez-les :
+
+@example
+# guix archive --authorize < ~root/.guix-profile/share/guix/hydra.gnu.org.pub
+@end example
+
+@item
+Each user may need to perform a few additional steps to make their Guix
+environment ready for use, @pxref{Réglages applicatifs}.
+@end enumerate
+
+Voilà, the installation is complete!
+
+You can confirm that Guix is working by installing a sample package into the
+root profile:
+
+@example
+# guix package -i hello
+@end example
+
+The @code{guix} package must remain available in @code{root}'s profile, or
+it would become subject to garbage collection---in which case you would find
+yourself badly handicapped by the lack of the @command{guix} command.  In
+other words, do not remove @code{guix} by running @code{guix package -r
+guix}.
+
+The binary installation tarball can be (re)produced and verified simply by
+running the following command in the Guix source tree:
+
+@example
+make guix-binary.@var{system}.tar.xz
+@end example
+
+@noindent
+... which, in turn, runs:
+
+@example
+guix pack -s @var{system} --localstatedir guix
+@end example
+
+@xref{Invoquer guix pack}, for more info on this handy tool.

+@section Prérequis
+
+This section lists requirements when building Guix from source.  The build
+procedure for Guix is the same as for other GNU software, and is not covered
+here.  Please see the files @file{README} and @file{INSTALL} in the Guix
+source tree for additional details.
+
+GNU Guix depends on the following packages:
+
+@itemize
+@item @url{http://gnu.org/software/guile/, GNU Guile}, version 2.0.13 or
+later, including 2.2.x;
+@item @url{http://gnupg.org/, GNU libgcrypt};
+@item
+@uref{http://gnutls.org/, GnuTLS}, specifically its Guile bindings
+(@pxref{Guile Preparations, how to install the GnuTLS bindings for Guile,,
+gnutls-guile, GnuTLS-Guile});
+@item
+@c FIXME: Specify a version number once a release has been made.
+@uref{https://gitlab.com/guile-git/guile-git, Guile-Git}, from August 2017
+or later;
+@item @url{http://zlib.net, zlib};
+@item @url{http://www.gnu.org/software/make/, GNU Make}.
+@end itemize
+
+The following dependencies are optional:
+
+@itemize
+@item
+Installing @url{http://savannah.nongnu.org/projects/guile-json/, Guile-JSON}
+will allow you to use the @command{guix import pypi} command
+(@pxref{Invoquer guix import}).  It is of interest primarily for developers
+and not for casual users.
+
+@item
+@c Note: We need at least 0.10.2 for 'channel-send-eof'.
+Support for build offloading (@pxref{Réglages du délestage du démon}) and
+@command{guix copy} (@pxref{Invoquer guix copy}) depends on
+@uref{https://github.com/artyom-poptsov/guile-ssh, Guile-SSH}, version
+0.10.2 or later.
+
+@item
+When @url{http://www.bzip.org, libbz2} is available, @command{guix-daemon}
+can use it to compress build logs.
+@end itemize
+
+Unless @code{--disable-daemon} was passed to @command{configure}, the
+following packages are also needed:
+
+@itemize
+@item @url{http://sqlite.org, SQLite 3};
+@item @url{http://gcc.gnu.org, GCC's g++}, with support for the
+C++11 standard.
+@end itemize
+
+@cindex state directory
+When configuring Guix on a system that already has a Guix installation, be
+sure to specify the same state directory as the existing installation using
+the @code{--localstatedir} option of the @command{configure} script
+(@pxref{Directory Variables, @code{localstatedir},, standards, GNU Coding
+Standards}).  The @command{configure} script protects against unintended
+misconfiguration of @var{localstatedir} so you do not inadvertently corrupt
+your store (@pxref{Le dépôt}).
+
+@cindex Nix, compatibility
+When a working installation of @url{http://nixos.org/nix/, the Nix package
+manager} is available, you can instead configure Guix with
+@code{--disable-daemon}.  In that case, Nix replaces the three dependencies
+above.
+
+Guix is compatible with Nix, so it is possible to share the same store
+between both.  To do so, you must pass @command{configure} not only the same
+@code{--with-store-dir} value, but also the same @code{--localstatedir}
+value.  The latter is essential because it specifies where the database that
+stores metadata about the store is located, among other things.  The default
+values for Nix are @code{--with-store-dir=/nix/store} and
+@code{--localstatedir=/nix/var}.  Note that @code{--disable-daemon} is not
+required if your goal is to share the store with Nix.
+
+@node Lancer la suite de tests
+@section Lancer la suite de tests
+
+@cindex test suite
+After a successful @command{configure} and @code{make} run, it is a good
+idea to run the test suite.  It can help catch issues with the setup or
+environment, or bugs in Guix itself---and really, reporting test failures is
+a good way to help improve the software.  To run the test suite, type:
+
+@example
+make check
+@end example
+
+Test cases can run in parallel: you can use the @code{-j} option of
+GNU@tie{}make to speed things up.  The first run may take a few minutes on a
+recent machine; subsequent runs will be faster because the store that is
+created for test purposes will already have various things in cache.
+
+It is also possible to run a subset of the tests by defining the
+@code{TESTS} makefile variable as in this example:
+
+@example
+make check TESTS="tests/store.scm tests/cpio.scm"
+@end example
+
+By default, tests results are displayed at a file level.  In order to see
+the details of every individual test cases, it is possible to define the
+@code{SCM_LOG_DRIVER_FLAGS} makefile variable as in this example:
+
+@example
+make check TESTS="tests/base64.scm" SCM_LOG_DRIVER_FLAGS="--brief=no"
+@end example
+
+Upon failure, please email @email{bug-guix@@gnu.org} and attach the
+@file{test-suite.log} file.  Please specify the Guix version being used as
+well as version numbers of the dependencies (@pxref{Prérequis}) in your
+message.
+
+Guix also comes with a whole-system test suite that tests complete GuixSD
+operating system instances.  It can only run on systems where Guix is
+already installed, using:
+
+@example
+make check-system
+@end example
+
+@noindent
+or, again, by defining @code{TESTS} to select a subset of tests to run:
+
+@example
+make check-system TESTS="basic mcron"
+@end example
+
+Ces tests systèmes sont définis dans les modules @code{(gnu tests
+@dots{})}. Ils fonctionnent en lançant les systèmes d'exploitation sous test
+avec une instrumentation légère dans une machine virtuelle (VM). Ils peuvent
+être intenses en terme de calculs ou plutôt rapides en fonction de la
+disponibilité des substituts de leurs dépendances
+(@pxref{Substituts}). Certains requièrent beaucoup d'espace disque pour
+contenir les images des VM.
+
+Again in case of test failures, please send @email{bug-guix@@gnu.org} all
+the details.

+Operations such as building a package or running the garbage collector are

+
+@cindex build environment
+In a standard multi-user setup, Guix and its daemon---the
+@command{guix-daemon} program---are installed by the system administrator;
+@file{/gnu/store} is owned by @code{root} and @command{guix-daemon} runs as
+@code{root}.  Unprivileged users may use Guix tools to build packages or
+otherwise access the store, and the daemon will do it on their behalf,
+ensuring that the store is kept in a consistent state, and allowing built
+packages to be shared among users.
+
+@cindex build users
+When @command{guix-daemon} runs as @code{root}, you may not want package
+build processes themselves to run as @code{root} too, for obvious security
+reasons.  To avoid that, a special pool of @dfn{build users} should be
+created for use by build processes started by the daemon.  These build users
+need not have a shell and a home directory: they will just be used when the
+daemon drops @code{root} privileges in build processes.  Having several such
+users allows the daemon to launch distinct build processes under separate
+UIDs, which guarantees that they do not interfere with each other---an
+essential feature since builds are regarded as pure functions
+(@pxref{Introduction}).
+
+On a GNU/Linux system, a build user pool may be created like this (using
+Bash syntax and the @code{shadow} commands):
+
+@c See http://lists.gnu.org/archive/html/bug-guix/2013-01/msg00239.html
+@c for why `-G' is needed.
+@example
+# groupadd --system guixbuild
+# for i in `seq -w 1 10`;
+  do
+    useradd -g guixbuild -G guixbuild           \
+            -d /var/empty -s `which nologin`    \
+            -c "Guix build user $i" --system    \
+            guixbuilder$i;
+  done
+@end example
+
+@noindent
+The number of build users determines how many build jobs may run in
+parallel, as specified by the @option{--max-jobs} option (@pxref{Invoquer guix-daemon, @option{--max-jobs}}).  To use @command{guix system vm} and
+related commands, you may need to add the build users to the @code{kvm}
+group so they can access @file{/dev/kvm}, using @code{-G guixbuild,kvm}
+instead of @code{-G guixbuild} (@pxref{Invoquer guix system}).
+
+The @code{guix-daemon} program may then be run as @code{root} with the
+following command@footnote{If your machine uses the systemd init system,
+dropping the @file{@var{prefix}/lib/systemd/system/guix-daemon.service} file
+in @file{/etc/systemd/system} will ensure that @command{guix-daemon} is
+automatically started.  Similarly, if your machine uses the Upstart init
+system, drop the @file{@var{prefix}/lib/upstart/system/guix-daemon.conf}
+file in @file{/etc/init}.}:
+
+@example
+# guix-daemon --build-users-group=guixbuild
+@end example
+
+@cindex chroot
+@noindent
+This way, the daemon starts build processes in a chroot, under one of the
+@code{guixbuilder} users.  On GNU/Linux, by default, the chroot environment
+contains nothing but:
+
+@c Keep this list in sync with libstore/build.cc! -----------------------
+@itemize
+@item
+a minimal @code{/dev} directory, created mostly independently from the host
+@code{/dev}@footnote{``Mostly'', because while the set of files that appear
+in the chroot's @code{/dev} is fixed, most of these files can only be
+created if the host has them.};
+
+@item
+the @code{/proc} directory; it only shows the processes of the container
+since a separate PID name space is used;
+
+@item
+@file{/etc/passwd} with an entry for the current user and an entry for user
+@file{nobody};
+
+@item
+@file{/etc/group} with an entry for the user's group;
+
+@item
+@file{/etc/hosts} with an entry that maps @code{localhost} to
+@code{127.0.0.1};
+
+@item
+a writable @file{/tmp} directory.
+@end itemize
+
+You can influence the directory where the daemon stores build trees @i{via}
+the @code{TMPDIR} environment variable.  However, the build tree within the
+chroot is always called @file{/tmp/guix-build-@var{name}.drv-0}, where
+@var{name} is the derivation name---e.g., @code{coreutils-8.24}.  This way,
+the value of @code{TMPDIR} does not leak inside build environments, which
+avoids discrepancies in cases where build processes capture the name of
+their build tree.
+
+@vindex http_proxy
+Le démon tient aussi compte de la variable d'environnement @code{http_proxy}
+pour ses téléchargements HTTP, que ce soit pour les dérivations à sortie
+fixes (@pxref{Dérivations}) ou pour les substituts (@pxref{Substituts}).
+
+If you are installing Guix as an unprivileged user, it is still possible to
+run @command{guix-daemon} provided you pass @code{--disable-chroot}.
+However, build processes will not be isolated from one another, and not from
+the rest of the system.  Thus, build processes may interfere with each
+other, and may access programs, libraries, and other files available on the
+system---making it much harder to view them as @emph{pure} functions.
+
+
+@node Réglages du délestage du démon
+@subsection Using the Offload Facility
+
+@cindex offloading
+@cindex build hook
+When desired, the build daemon can @dfn{offload} derivation builds to other
+machines running Guix, using the @code{offload} @dfn{build
+hook}@footnote{This feature is available only when
+@uref{https://github.com/artyom-poptsov/guile-ssh, Guile-SSH} is present.}.
+When that feature is enabled, a list of user-specified build machines is
+read from @file{/etc/guix/machines.scm}; every time a build is requested,
+for instance via @code{guix build}, the daemon attempts to offload it to one
+of the machines that satisfy the constraints of the derivation, in
+particular its system type---e.g., @file{x86_64-linux}.  Missing
+prerequisites for the build are copied over SSH to the target machine, which
+then proceeds with the build; upon success the output(s) of the build are
+copied back to the initial machine.
+
+The @file{/etc/guix/machines.scm} file typically looks like this:
+
+@example
+(list (build-machine
+        (name "eightysix.example.org")
+        (system "x86_64-linux")
+        (host-key "ssh-ed25519 AAAAC3Nza@dots{}")
+        (user "bob")
+        (speed 2.))     ;incredibly fast!
+
+      (build-machine
+        (name "meeps.example.org")
+        (system "mips64el-linux")
+        (host-key "ssh-rsa AAAAB3Nza@dots{}")
+        (user "alice")
+        (private-key
+         (string-append (getenv "HOME")
+                        "/.ssh/identity-for-guix"))))
+@end example
+
+@noindent
+In the example above we specify a list of two build machines, one for the
+@code{x86_64} architecture and one for the @code{mips64el} architecture.
+
+In fact, this file is---not surprisingly!---a Scheme file that is evaluated
+when the @code{offload} hook is started.  Its return value must be a list of
+@code{build-machine} objects.  While this example shows a fixed list of
+build machines, one could imagine, say, using DNS-SD to return a list of
+potential build machines discovered in the local network
+(@pxref{Introduction, Guile-Avahi,, guile-avahi, Using Avahi in Guile Scheme
+Programs}).  The @code{build-machine} data type is detailed below.
+
+@deftp {Data Type} build-machine
+This data type represents build machines to which the daemon may offload
+builds.  The important fields are:
+
+@table @code
+
+@item name
+The host name of the remote machine.
+
+@item system
+The system type of the remote machine---e.g., @code{"x86_64-linux"}.
+
+@item user
+The user account to use when connecting to the remote machine over SSH.
+Note that the SSH key pair must @emph{not} be passphrase-protected, to allow
+non-interactive logins.
+
+@item host-key
+This must be the machine's SSH @dfn{public host key} in OpenSSH format.
+This is used to authenticate the machine when we connect to it.  It is a
+long string that looks like this:
+
+@example
+ssh-ed25519 AAAAC3NzaC@dots{}mde+UhL hint@@example.org
+@end example
+
+If the machine is running the OpenSSH daemon, @command{sshd}, the host key
+can be found in a file such as @file{/etc/ssh/ssh_host_ed25519_key.pub}.
+
+If the machine is running the SSH daemon of GNU@tie{}lsh, @command{lshd},
+the host key is in @file{/etc/lsh/host-key.pub} or a similar file.  It can
+be converted to the OpenSSH format using @command{lsh-export-key}
+(@pxref{Converting keys,,, lsh, LSH Manual}):
+
+@example
+$ lsh-export-key --openssh < /etc/lsh/host-key.pub 
+ssh-rsa AAAAB3NzaC1yc2EAAAAEOp8FoQAAAQEAs1eB46LV@dots{}
+@end example
+
+@end table
+
+A number of optional fields may be specified:
+
+@table @asis
+
+@item @code{port} (default: @code{22})
+Port number of SSH server on the machine.
+
+@item @code{private-key} (default: @file{~root/.ssh/id_rsa})
+The SSH private key file to use when connecting to the machine, in OpenSSH
+format.
+
+Note that the default value is the private key @emph{of the root account}.
+Make sure it exists if you use the default.
+
+@item @code{compression} (default: @code{"zlib@@openssh.com,zlib"})
+@itemx @code{compression-level} (default: @code{3})
+The SSH-level compression methods and compression level requested.
+
+Note that offloading relies on SSH compression to reduce bandwidth usage
+when transferring files to and from build machines.
+
+@item @code{daemon-socket} (default: @code{"/var/guix/daemon-socket/socket"})
+File name of the Unix-domain socket @command{guix-daemon} is listening to on
+that machine.
+
+@item @code{parallel-builds} (default: @code{1})
+The number of builds that may run in parallel on the machine.
+
+@item @code{speed} (default: @code{1.0})
+A ``relative speed factor''.  The offload scheduler will tend to prefer
+machines with a higher speed factor.
+
+@item @code{features} (default: @code{'()})
+A list of strings denoting specific features supported by the machine.  An
+example is @code{"kvm"} for machines that have the KVM Linux modules and
+corresponding hardware support.  Derivations can request features by name,
+and they will be scheduled on matching build machines.
+
+@end table
+@end deftp
+
+The @code{guile} command must be in the search path on the build machines.
+In addition, the Guix modules must be in @code{$GUILE_LOAD_PATH} on the
+build machine---you can check whether this is the case by running:
+
+@example
+ssh build-machine guile -c "'(use-modules (guix config))'"
+@end example
+
+There is one last thing to do once @file{machines.scm} is in place.  As
+explained above, when offloading, files are transferred back and forth
+between the machine stores.  For this to work, you first need to generate a
+key pair on each machine to allow the daemon to export signed archives of
+files from the store (@pxref{Invoquer guix archive}):
+
+@example
+# guix archive --generate-key
+@end example
+
+@noindent
+Each build machine must authorize the key of the master machine so that it
+accepts store items it receives from the master:
+
+@example
+# guix archive --authorize < master-public-key.txt
+@end example
+
+@noindent
+Likewise, the master machine must authorize the key of each build machine.
+
+All the fuss with keys is here to express pairwise mutual trust relations
+between the master and the build machines.  Concretely, when the master
+receives files from a build machine (and @i{vice versa}), its build daemon
+can make sure they are genuine, have not been tampered with, and that they
+are signed by an authorized key.
+
+@cindex offload test
+To test whether your setup is operational, run this command on the master
+node:
+
+@example
+# guix offload test
+@end example
+
+This will attempt to connect to each of the build machines specified in
+@file{/etc/guix/machines.scm}, make sure Guile and the Guix modules are
+available on each machine, attempt to export to the machine and import from
+it, and report any error in the process.
+
+If you want to test a different machine file, just specify it on the command
+line:
+
+@example
+# guix offload test machines-qualif.scm
+@end example
+
+Last, you can test the subset of the machines whose name matches a regular
+expression like this:
+
+@example
+# guix offload test machines.scm '\.gnu\.org$'
+@end example
+
+@cindex offload status
+To display the current load of all build hosts, run this command on the main
+node:
+
+@example
+# guix offload status
+@end example
+
+
+@node Support de SELinux
+@subsection Support de SELinux
+
+@cindex SELinux, daemon policy
+@cindex mandatory access control, SELinux
+@cindex security, guix-daemon
+Guix includes an SELinux policy file at @file{etc/guix-daemon.cil} that can
+be installed on a system where SELinux is enabled, in order to label Guix
+files and to specify the expected behavior of the daemon.  Since GuixSD does
+not provide an SELinux base policy, the daemon policy cannot be used on
+GuixSD.
+
+@subsubsection Installing the SELinux policy
+@cindex SELinux, policy installation
+To install the policy run this command as root:
+
+@example
+semodule -i etc/guix-daemon.cil
+@end example
+
+Then relabel the file system with @code{restorecon} or by a different
+mechanism provided by your system.
+
+Once the policy is installed, the file system has been relabeled, and the
+daemon has been restarted, it should be running in the @code{guix_daemon_t}
+context.  You can confirm this with the following command:
+
+@example
+ps -Zax | grep guix-daemon
+@end example
+
+Monitor the SELinux log files as you run a command like @code{guix build
+hello} to convince yourself that SELinux permits all necessary operations.
+
+@subsubsection Limitations
+@cindex SELinux, limitations
+
+This policy is not perfect.  Here is a list of limitations or quirks that
+should be considered when deploying the provided SELinux policy for the Guix
+daemon.
+
+@enumerate
+@item
+@code{guix_daemon_socket_t} isn’t actually used.  None of the socket
+operations involve contexts that have anything to do with
+@code{guix_daemon_socket_t}.  It doesn’t hurt to have this unused label, but
+it would be preferrable to define socket rules for only this label.
+
+@item
+@code{guix gc} cannot access arbitrary links to profiles.  By design, the
+file label of the destination of a symlink is independent of the file label
+of the link itself.  Although all profiles under $localstatedir are
+labelled, the links to these profiles inherit the label of the directory
+they are in.  For links in the user’s home directory this will be
+@code{user_home_t}.  But for links from the root user’s home directory, or
+@file{/tmp}, or the HTTP server’s working directory, etc, this won’t work.
+@code{guix gc} would be prevented from reading and following these links.
+
+@item
+The daemon’s feature to listen for TCP connections might no longer work.
+This might require extra rules, because SELinux treats network sockets
+differently from files.
+
+@item
+Currently all files with a name matching the regular expression
+@code{/gnu/store/.+-(guix-.+|profile)/bin/guix-daemon} are assigned the
+label @code{guix_daemon_exec_t}; this means that @emph{any} file with that
+name in any profile would be permitted to run in the @code{guix_daemon_t}
+domain.  This is not ideal.  An attacker could build a package that provides
+this executable and convince a user to install and run it, which lifts it
+into the @code{guix_daemon_t} domain.  At that point SELinux could not
+prevent it from accessing files that are allowed for processes in that
+domain.
+
+We could generate a much more restrictive policy at installation time, so
+that only the @emph{exact} file name of the currently installed
+@code{guix-daemon} executable would be labelled with
+@code{guix_daemon_exec_t}, instead of using a broad regular expression.  The
+downside is that root would have to install or upgrade the policy at
+installation time whenever the Guix package that provides the effectively
+running @code{guix-daemon} executable is upgraded.
+@end enumerate
+
+@node Invoquer guix-daemon
+@section Invoking @command{guix-daemon}
+
+The @command{guix-daemon} program implements all the functionality to access
+the store.  This includes launching build processes, running the garbage
+collector, querying the availability of a build result, etc.  It is normally
+run as @code{root} like this:
+
+@example
+# guix-daemon --build-users-group=guixbuild
+@end example
+
+@noindent
+Pour des détails sur son paramétrage, @pxref{Paramétrer le démon}.
+
+@cindex chroot
+@cindex container, build environment
+@cindex build environment
+@cindex reproducible builds
+Par défaut, @command{guix-daemon} lance les processus de construction sous
+différents UID récupérés depuis le groupe de construction spécifié avec
+@code{--build-users-group}. En plus, chaque processus de construction est
+lancé dans un environnement chroot qui ne contient que le sous-ensemble du
+dépôt dont le processus de construction dépend, tel que spécifié par sa
+dérivation (@pxref{Interface de programmation, dérivation}), plus un
+ensemble de répertoires systèmes spécifiques. Par défaut ce dernier contient
+@file{/dev} et @file{/dev/pts}. De plus, sous GNU/Linux, l'environnement de
+construction est un @dfn{conteneur} : en plus d'avoir sa propre arborescence
+du système de fichier, elle a un espace de montage séparé, son propre espace
+de PID, son espace de réseau, etc. Cela aide à obtenir des constructions
+reproductibles (@pxref{Fonctionnalités}).
+
+When the daemon performs a build on behalf of the user, it creates a build
+directory under @file{/tmp} or under the directory specified by its
+@code{TMPDIR} environment variable; this directory is shared with the
+container for the duration of the build.  Be aware that using a directory
+other than @file{/tmp} can affect build results---for example, with a longer
+directory name, a build process that uses Unix-domain sockets might hit the
+name length limitation for @code{sun_path}, which it would otherwise not
+hit.
+
+The build directory is automatically deleted upon completion, unless the
+build failed and the client specified @option{--keep-failed}
+(@pxref{Invoquer guix build, @option{--keep-failed}}).
+
+The following command-line options are supported:
+
+@table @code
+@item --build-users-group=@var{group}
+Prend les utilisateurs de @var{group} pour lancer les processus de
+construction (@pxref{Paramétrer le démon, utilisateurs de construction}).
+
+@item --no-substitutes
+@cindex substitutes
+Ne pas utiliser de substitut pour les résultats de la
+construction. C'est-à-dire, toujours construire localement plutôt que de
+permettre le téléchargement de binaires pré-construits (@pxref{Substituts}).
+
+When the daemon runs with @code{--no-substitutes}, clients can still
+explicitly enable substitution @i{via} the @code{set-build-options} remote
+procedure call (@pxref{Le dépôt}).
+
+@item --substitute-urls=@var{urls}
+@anchor{daemon-substitute-urls}
+Consider @var{urls} the default whitespace-separated list of substitute
+source URLs.  When this option is omitted,
+@indicateurl{https://mirror.hydra.gnu.org https://hydra.gnu.org} is used
+(@code{mirror.hydra.gnu.org} is a mirror of @code{hydra.gnu.org}).
+
+Cela signifie que les substituts sont téléchargés depuis les @var{urls},
+tant qu'ils sont signés par une signature de confiance (@pxref{Substituts}).
+
+@cindex build hook
+@item --no-build-hook
+Do not use the @dfn{build hook}.
+
+The build hook is a helper program that the daemon can start and to which it
+submits build requests.  This mechanism is used to offload builds to other
+machines (@pxref{Réglages du délestage du démon}).
+
+@item --cache-failures
+Cache build failures.  By default, only successful builds are cached.
+
+When this option is used, @command{guix gc --list-failures} can be used to
+query the set of store items marked as failed; @command{guix gc
+--clear-failures} removes store items from the set of cached failures.
+@xref{Invoquer guix gc}.
+
+@item --cores=@var{n}
+@itemx -c @var{n}
+Use @var{n} CPU cores to build each derivation; @code{0} means as many as
+available.
+
+The default value is @code{0}, but it may be overridden by clients, such as
+the @code{--cores} option of @command{guix build} (@pxref{Invoquer guix build}).
+
+The effect is to define the @code{NIX_BUILD_CORES} environment variable in
+the build process, which can then use it to exploit internal
+parallelism---for instance, by running @code{make -j$NIX_BUILD_CORES}.
+
+@item --max-jobs=@var{n}
+@itemx -M @var{n}
+Allow at most @var{n} build jobs in parallel.  The default value is
+@code{1}.  Setting it to @code{0} means that no builds will be performed
+locally; instead, the daemon will offload builds (@pxref{Réglages du délestage du démon}), or simply fail.
+
+@item --max-silent-time=@var{seconds}
+When the build or substitution process remains silent for more than
+@var{seconds}, terminate it and report a build failure.
+
+The default value is @code{0}, which disables the timeout.
+
+The value specified here can be overridden by clients (@pxref{Options de construction communes, @code{--max-silent-time}}).
+
+@item --timeout=@var{seconds}
+Likewise, when the build or substitution process lasts for more than
+@var{seconds}, terminate it and report a build failure.
+
+The default value is @code{0}, which disables the timeout.
+
+The value specified here can be overridden by clients (@pxref{Options de construction communes, @code{--timeout}}).
+
+@item --rounds=@var{N}
+Build each derivation @var{n} times in a row, and raise an error if
+consecutive build results are not bit-for-bit identical.  Note that this
+setting can be overridden by clients such as @command{guix build}
+(@pxref{Invoquer guix build}).
+
+When used in conjunction with @option{--keep-failed}, the differing output
+is kept in the store, under @file{/gnu/store/@dots{}-check}.  This makes it
+easy to look for differences between the two results.
+
+@item --debug
+Produce debugging output.
+
+This is useful to debug daemon start-up issues, but then it may be
+overridden by clients, for example the @code{--verbosity} option of
+@command{guix build} (@pxref{Invoquer guix build}).
+
+@item --chroot-directory=@var{dir}
+Add @var{dir} to the build chroot.
+
+Doing this may change the result of build processes---for instance if they
+use optional dependencies found in @var{dir} when it is available, and not
+otherwise.  For that reason, it is not recommended to do so.  Instead, make
+sure that each derivation declares all the inputs that it needs.
+
+@item --disable-chroot
+Disable chroot builds.
+
+Using this option is not recommended since, again, it would allow build
+processes to gain access to undeclared dependencies.  It is necessary,
+though, when @command{guix-daemon} is running under an unprivileged user
+account.
+
+@item --log-compression=@var{type}
+Compress build logs according to @var{type}, one of @code{gzip},
+@code{bzip2}, or @code{none}.
+
+Unless @code{--lose-logs} is used, all the build logs are kept in the
+@var{localstatedir}.  To save space, the daemon automatically compresses
+them with bzip2 by default.
+
+@item --disable-deduplication
+@cindex deduplication
+Disable automatic file ``deduplication'' in the store.
+
+By default, files added to the store are automatically ``deduplicated'': if
+a newly added file is identical to another one found in the store, the
+daemon makes the new file a hard link to the other file.  This can
+noticeably reduce disk usage, at the expense of slightly increased
+input/output load at the end of a build process.  This option disables this
+optimization.
+
+@item --gc-keep-outputs[=yes|no]
+Tell whether the garbage collector (GC) must keep outputs of live
+derivations.
+
+@cindex GC roots
+@cindex garbage collector roots
+When set to ``yes'', the GC will keep the outputs of any live derivation
+available in the store---the @code{.drv} files.  The default is ``no'',
+meaning that derivation outputs are kept only if they are GC roots.
+@xref{Invoquer guix gc}, for more on GC roots.
+
+@item --gc-keep-derivations[=yes|no]
+Tell whether the garbage collector (GC) must keep derivations corresponding
+to live outputs.
+
+When set to ``yes'', as is the case by default, the GC keeps
+derivations---i.e., @code{.drv} files---as long as at least one of their
+outputs is live.  This allows users to keep track of the origins of items in
+their store.  Setting it to ``no'' saves a bit of disk space.
+
+Note that when both @code{--gc-keep-derivations} and
+@code{--gc-keep-outputs} are used, the effect is to keep all the build
+prerequisites (the sources, compiler, libraries, and other build-time tools)
+of live objects in the store, regardless of whether these prerequisites are
+live.  This is convenient for developers since it saves rebuilds or
+downloads.
+
+@item --impersonate-linux-2.6
+On Linux-based systems, impersonate Linux 2.6.  This means that the kernel's
+@code{uname} system call will report 2.6 as the release number.
+
+This might be helpful to build programs that (usually wrongfully) depend on
+the kernel version number.
+
+@item --lose-logs
+Do not keep build logs.  By default they are kept under
+@code{@var{localstatedir}/guix/log}.
+
+@item --system=@var{system}
+Assume @var{system} as the current system type.  By default it is the
+architecture/kernel pair found at configure time, such as
+@code{x86_64-linux}.
+
+@item --listen=@var{endpoint}
+Listen for connections on @var{endpoint}.  @var{endpoint} is interpreted as
+the file name of a Unix-domain socket if it starts with @code{/} (slash
+sign).  Otherwise, @var{endpoint} is interpreted as a host name or host name
+and port to listen to.  Here are a few examples:
+
+@table @code
+@item --listen=/gnu/var/daemon
+Listen for connections on the @file{/gnu/var/daemon} Unix-domain socket,
+creating it if needed.
+
+@item --listen=localhost
+@cindex daemon, remote access
+@cindex remote access to the daemon
+@cindex daemon, cluster setup
+@cindex clusters, daemon setup
+Listen for TCP connections on the network interface corresponding to
+@code{localhost}, on port 44146.
+
+@item --listen=128.0.0.42:1234
+Listen for TCP connections on the network interface corresponding to
+@code{128.0.0.42}, on port 1234.
+@end table
+
+This option can be repeated multiple times, in which case
+@command{guix-daemon} accepts connections on all the specified endpoints.
+Users can tell client commands what endpoint to connect to by setting the
+@code{GUIX_DAEMON_SOCKET} environment variable (@pxref{Le dépôt,
+@code{GUIX_DAEMON_SOCKET}}).
+
+@quotation Note
+The daemon protocol is @emph{unauthenticated and unencrypted}.  Using
+@code{--listen=@var{host}} is suitable on local networks, such as clusters,
+where only trusted nodes may connect to the build daemon.  In other cases
+where remote access to the daemon is needed, we recommend using Unix-domain
+sockets along with SSH.
+@end quotation
+
+When @code{--listen} is omitted, @command{guix-daemon} listens for
+connections on the Unix-domain socket located at
+@file{@var{localstatedir}/guix/daemon-socket/socket}.
+@end table
+
+
+@node Réglages applicatifs
+@section Réglages applicatifs
+
+@cindex distro extérieure
+When using Guix on top of GNU/Linux distribution other than GuixSD---a
+so-called @dfn{foreign distro}---a few additional steps are needed to get
+everything in place.  Here are some of them.
+
+@subsection Régionalisation
+
+@anchor{locales-and-locpath}
+@cindex locales, when not on GuixSD
+@vindex LOCPATH
+@vindex GUIX_LOCPATH
+Packages installed @i{via} Guix will not use the locale data of the host
+system.  Instead, you must first install one of the locale packages
+available with Guix and then define the @code{GUIX_LOCPATH} environment
+variable:
+
+@example
+$ guix package -i glibc-locales
+$ export GUIX_LOCPATH=$HOME/.guix-profile/lib/locale
+@end example
+
+Note that the @code{glibc-locales} package contains data for all the locales
+supported by the GNU@tie{}libc and weighs in at around 110@tie{}MiB.
+Alternatively, the @code{glibc-utf8-locales} is smaller but limited to a few
+UTF-8 locales.
+
+The @code{GUIX_LOCPATH} variable plays a role similar to @code{LOCPATH}
+(@pxref{Locale Names, @code{LOCPATH},, libc, The GNU C Library Reference
+Manual}).  There are two important differences though:
+
+@enumerate
+@item
+@code{GUIX_LOCPATH} is honored only by the libc in Guix, and not by the libc
+provided by foreign distros.  Thus, using @code{GUIX_LOCPATH} allows you to
+make sure the programs of the foreign distro will not end up loading
+incompatible locale data.
+
+@item
+libc suffixes each entry of @code{GUIX_LOCPATH} with @code{/X.Y}, where
+@code{X.Y} is the libc version---e.g., @code{2.22}.  This means that, should
+your Guix profile contain a mixture of programs linked against different
+libc version, each libc version will only try to load locale data in the
+right format.
+@end enumerate
+
+This is important because the locale data format used by different libc
+versions may be incompatible.
+
+@subsection Name Service Switch
+
+@cindex name service switch, glibc
+@cindex NSS (name service switch), glibc
+@cindex nscd (name service caching daemon)
+@cindex name service caching daemon (nscd)
+When using Guix on a foreign distro, we @emph{strongly recommend} that the
+system run the GNU C library's @dfn{name service cache daemon},
+@command{nscd}, which should be listening on the @file{/var/run/nscd/socket}
+socket.  Failing to do that, applications installed with Guix may fail to
+look up host names or user accounts, or may even crash.  The next paragraphs
+explain why.
+
+@cindex @file{nsswitch.conf}
+The GNU C library implements a @dfn{name service switch} (NSS), which is an
+extensible mechanism for ``name lookups'' in general: host name resolution,
+user accounts, and more (@pxref{Name Service Switch,,, libc, The GNU C
+Library Reference Manual}).
+
+@cindex Network information service (NIS)
+@cindex NIS (Network information service)
+Being extensible, the NSS supports @dfn{plugins}, which provide new name
+lookup implementations: for example, the @code{nss-mdns} plugin allow
+resolution of @code{.local} host names, the @code{nis} plugin allows user
+account lookup using the Network information service (NIS), and so on.
+These extra ``lookup services'' are configured system-wide in
+@file{/etc/nsswitch.conf}, and all the programs running on the system honor
+those settings (@pxref{NSS Configuration File,,, libc, The GNU C Reference
+Manual}).
+
+When they perform a name lookup---for instance by calling the
+@code{getaddrinfo} function in C---applications first try to connect to the
+nscd; on success, nscd performs name lookups on their behalf.  If the nscd
+is not running, then they perform the name lookup by themselves, by loading
+the name lookup services into their own address space and running it.  These
+name lookup services---the @file{libnss_*.so} files---are @code{dlopen}'d,
+but they may come from the host system's C library, rather than from the C
+library the application is linked against (the C library coming from Guix).
+
+And this is where the problem is: if your application is linked against
+Guix's C library (say, glibc 2.24) and tries to load NSS plugins from
+another C library (say, @code{libnss_mdns.so} for glibc 2.22), it will
+likely crash or have its name lookups fail unexpectedly.
+
+Running @command{nscd} on the system, among other advantages, eliminates
+this binary incompatibility problem because those @code{libnss_*.so} files
+are loaded in the @command{nscd} process, not in applications themselves.
+
+@subsection X11 Fonts
+
+@cindex fonts
+The majority of graphical applications use Fontconfig to locate and load
+fonts and perform X11-client-side rendering.  The @code{fontconfig} package
+in Guix looks for fonts in @file{$HOME/.guix-profile} by default.  Thus, to
+allow graphical applications installed with Guix to display fonts, you have
+to install fonts with Guix as well.  Essential font packages include
+@code{gs-fonts}, @code{font-dejavu}, and @code{font-gnu-freefont-ttf}.
+
+To display text written in Chinese languages, Japanese, or Korean in
+graphical applications, consider installing
+@code{font-adobe-source-han-sans} or @code{font-wqy-zenhei}.  The former has
+multiple outputs, one per language family (@pxref{Des paquets avec plusieurs résultats}).  For instance, the following command installs fonts for Chinese
+languages:
+
+@example
+guix package -i font-adobe-source-han-sans:cn
+@end example
+
+@cindex @code{xterm}
+Older programs such as @command{xterm} do not use Fontconfig and instead
+rely on server-side font rendering.  Such programs require to specify a full
+name of a font using XLFD (X Logical Font Description), like this:
+
+@example
+-*-dejavu sans-medium-r-normal-*-*-100-*-*-*-*-*-1
+@end example
+
+To be able to use such full names for the TrueType fonts installed in your
+Guix profile, you need to extend the font path of the X server:
+
+@c Note: 'xset' does not accept symlinks so the trick below arranges to
+@c get at the real directory.  See <https://bugs.gnu.org/30655>.
+@example
+xset +fp $(dirname $(readlink -f ~/.guix-profile/share/fonts/truetype/fonts.dir))
+@end example
+
+@cindex @code{xlsfonts}
+After that, you can run @code{xlsfonts} (from @code{xlsfonts} package)  to
+make sure your TrueType fonts are listed there.
+
+@cindex @code{fc-cache}
+@cindex font cache
+After installing fonts you may have to refresh the font cache to use them in
+applications.  The same applies when applications installed via Guix do not
+seem to find fonts.  To force rebuilding of the font cache run
+@code{fc-cache -f}.  The @code{fc-cache} command is provided by the
+@code{fontconfig} package.
+
+@subsection Certificats X.509
+
+@cindex @code{nss-certs}
+The @code{nss-certs} package provides X.509 certificates, which allow
+programs to authenticate Web servers accessed over HTTPS.
+
+When using Guix on a foreign distro, you can install this package and define
+the relevant environment variables so that packages know where to look for
+certificates.  @xref{Certificats X.509}, for detailed information.
+
+@subsection Emacs Packages
+
+@cindex @code{emacs}
+When you install Emacs packages with Guix, the elisp files may be placed
+either in @file{$HOME/.guix-profile/share/emacs/site-lisp/} or in
+sub-directories of
+@file{$HOME/.guix-profile/share/emacs/site-lisp/guix.d/}.  The latter
+directory exists because potentially there may exist thousands of Emacs
+packages and storing all their files in a single directory may not be
+reliable (because of name conflicts).  So we think using a separate
+directory for each package is a good idea.  It is very similar to how the
+Emacs package system organizes the file structure (@pxref{Package Files,,,
+emacs, The GNU Emacs Manual}).
+
+By default, Emacs (installed with Guix) ``knows'' where these packages are
+placed, so you do not need to perform any configuration.  If, for some
+reason, you want to avoid auto-loading Emacs packages installed with Guix,
+you can do so by running Emacs with @code{--no-site-file} option
+(@pxref{Init File,,, emacs, The GNU Emacs Manual}).
+
+@subsection The GCC toolchain
+
+@cindex GCC
+@cindex ld-wrapper
+
+Guix offers individual compiler packages such as @code{gcc} but if you are
+in need of a complete toolchain for compiling and linking source code what
+you really want is the @code{gcc-toolchain} package.  This package provides
+a complete GCC toolchain for C/C++ development, including GCC itself, the
+GNU C Library (headers and binaries, plus debugging symbols in the
+@code{debug} output), Binutils, and a linker wrapper.
+
+@cindex attempt to use impure library, error message
+
+The wrapper's purpose is to inspect the @code{-L} and @code{-l} switches
+passed to the linker, add corresponding @code{-rpath} arguments, and invoke
+the actual linker with this new set of arguments.  By default, the linker
+wrapper refuses to link to libraries outside the store to ensure
+``purity''.  This can be annoying when using the toolchain to link with
+local libraries.  To allow references to libraries outside the store you
+need to define the environment variable
+@code{GUIX_LD_WRAPPER_ALLOW_IMPURITIES}.

+The purpose of GNU Guix is to allow users to easily install, upgrade, and
+remove software packages, without having to know about their build
+procedures or dependencies.  Guix also goes beyond this obvious set of
+features.

+
+When using Guix, each package ends up in the @dfn{package store}, in its own
+directory---something that resembles @file{/gnu/store/xxx-package-1.2},
+where @code{xxx} is a base32 string.
+
+Instead of referring to these directories, users have their own
+@dfn{profile}, which points to the packages that they actually want to use.
+These profiles are stored within each user's home directory, at
+@code{$HOME/.guix-profile}.
+
+For example, @code{alice} installs GCC 4.7.2.  As a result,
+@file{/home/alice/.guix-profile/bin/gcc} points to
+@file{/gnu/store/@dots{}-gcc-4.7.2/bin/gcc}.  Now, on the same machine,
+@code{bob} had already installed GCC 4.8.0.  The profile of @code{bob}
+simply continues to point to
+@file{/gnu/store/@dots{}-gcc-4.8.0/bin/gcc}---i.e., both versions of GCC
+coexist on the same system without any interference.
+
+The @command{guix package} command is the central tool to manage packages
+(@pxref{Invoquer guix package}).  It operates on the per-user profiles, and
+can be used @emph{with normal user privileges}.
+
+@cindex transactions
+The command provides the obvious install, remove, and upgrade operations.
+Each invocation is actually a @emph{transaction}: either the specified
+operation succeeds, or nothing happens.  Thus, if the @command{guix package}
+process is terminated during the transaction, or if a power outage occurs
+during the transaction, then the user's profile remains in its previous
+state, and remains usable.
+
+In addition, any package transaction may be @emph{rolled back}.  So, if, for
+example, an upgrade installs a new version of a package that turns out to
+have a serious bug, users may roll back to the previous instance of their
+profile, which was known to work well.  Similarly, the global system
+configuration on GuixSD is subject to transactional upgrades and roll-back
+(@pxref{Utiliser le système de configuration}).
+
+All packages in the package store may be @emph{garbage-collected}.  Guix can
+determine which packages are still referenced by user profiles, and remove
+those that are provably no longer referenced (@pxref{Invoquer guix gc}).
+Users may also explicitly remove old generations of their profile so that
+the packages they refer to can be collected.
+
+@cindex reproducibility
+@cindex reproducible builds
+Finally, Guix takes a @dfn{purely functional} approach to package
+management, as described in the introduction (@pxref{Introduction}).  Each
+@file{/gnu/store} package directory name contains a hash of all the inputs
+that were used to build that package---compiler, libraries, build scripts,
+etc.  This direct correspondence allows users to make sure a given package
+installation matches the current state of their distribution.  It also helps
+maximize @dfn{build reproducibility}: thanks to the isolated build
+environments that are used, a given build is likely to yield bit-identical
+files when performed on different machines (@pxref{Invoquer guix-daemon,
+container}).
+
+@cindex substitutes
+Ce fondement permet à Guix de supporter le @dfn{déploiement transparent de
+binaire ou source}. Lorsqu'une binaire pré-construit pour une entrée de
+@file{/gnu/store} est disponible depuis une source externe (un
+@dfn{substitut}), Guix le télécharge simplement et le décompresse ; sinon,
+il construit le paquet depuis les sources localement
+(@pxref{Substituts}). Comme les résultats des constructions sont
+généralement reproductibles au bit près, si vous n'avez pas besoin de faire
+confiance aux serveurs qui fournissent les substituts : vous pouvez forcer
+une construction locale et @emph{défier} les fournisseurs (@pxref{Invoquer guix challenge}).
+
+Control over the build environment is a feature that is also useful for
+developers.  The @command{guix environment} command allows developers of a
+package to quickly set up the right development environment for their
+package, without having to manually install the dependencies of the package
+into their profile (@pxref{Invoquer guix environment}).
+
+@node Invoquer guix package
+@section Invoking @command{guix package}
+
+@cindex installing packages
+@cindex removing packages
+@cindex package installation
+@cindex package removal
+La commande @command{guix package} est l'outil qui permet d'installer,
+mettre à jour et supprimer les paquets ainsi que de revenir à une
+configuration précédente. Elle n'opère que dans le profil de l'utilisateur
+et fonctionne avec les privilèges utilisateurs normaux
+(@pxref{Fonctionnalités}). Sa syntaxe est :
+
+@example
+guix package @var{options}
+@end example
+@cindex transactions
+Primarily, @var{options} specifies the operations to be performed during the
+transaction.  Upon completion, a new profile is created, but previous
+@dfn{generations} of the profile remain available, should the user want to
+roll back.
+
+For example, to remove @code{lua} and install @code{guile} and
+@code{guile-cairo} in a single transaction:
+
+@example
+guix package -r lua -i guile guile-cairo
+@end example
+
+@command{guix package} also supports a @dfn{declarative approach} whereby
+the user specifies the exact set of packages to be available and passes it
+@i{via} the @option{--manifest} option (@pxref{profile-manifest,
+@option{--manifest}}).
+
+@cindex profile
+For each user, a symlink to the user's default profile is automatically
+created in @file{$HOME/.guix-profile}.  This symlink always points to the
+current generation of the user's default profile.  Thus, users can add
+@file{$HOME/.guix-profile/bin} to their @code{PATH} environment variable,
+and so on.
+@cindex search paths
+If you are not using the Guix System Distribution, consider adding the
+following lines to your @file{~/.bash_profile} (@pxref{Bash Startup Files,,,
+bash, The GNU Bash Reference Manual}) so that newly-spawned shells get all
+the right environment variable definitions:
+
+@example
+GUIX_PROFILE="$HOME/.guix-profile" ; \
+source "$HOME/.guix-profile/etc/profile"
+@end example
+
+In a multi-user setup, user profiles are stored in a place registered as a
+@dfn{garbage-collector root}, which @file{$HOME/.guix-profile} points to
+(@pxref{Invoquer guix gc}).  That directory is normally
+@code{@var{localstatedir}/guix/profiles/per-user/@var{user}}, where
+@var{localstatedir} is the value passed to @code{configure} as
+@code{--localstatedir}, and @var{user} is the user name.  The
+@file{per-user} directory is created when @command{guix-daemon} is started,
+and the @var{user} sub-directory is created by @command{guix package}.
+
+The @var{options} can be among the following:
+
+@table @code
+
+@item --install=@var{package} @dots{}
+@itemx -i @var{package} @dots{}
+Install the specified @var{package}s.
+
+Each @var{package} may specify either a simple package name, such as
+@code{guile}, or a package name followed by an at-sign and version number,
+such as @code{guile@@1.8.8} or simply @code{guile@@1.8} (in the latter case,
+the newest version prefixed by @code{1.8} is selected.)
+
+If no version number is specified, the newest available version will be
+selected.  In addition, @var{package} may contain a colon, followed by the
+name of one of the outputs of the package, as in @code{gcc:doc} or
+@code{binutils@@2.22:lib} (@pxref{Des paquets avec plusieurs résultats}).
+Packages with a corresponding name (and optionally version) are searched for
+among the GNU distribution modules (@pxref{Modules de paquets}).
+
+@cindex propagated inputs
+Sometimes packages have @dfn{propagated inputs}: these are dependencies that
+automatically get installed along with the required package
+(@pxref{package-propagated-inputs, @code{propagated-inputs} in
+@code{package} objects}, for information about propagated inputs in package
+definitions).
+
+@anchor{package-cmd-propagated-inputs}
+An example is the GNU MPC library: its C header files refer to those of the
+GNU MPFR library, which in turn refer to those of the GMP library.  Thus,
+when installing MPC, the MPFR and GMP libraries also get installed in the
+profile; removing MPC also removes MPFR and GMP---unless they had also been
+explicitly installed by the user.
+
+Besides, packages sometimes rely on the definition of environment variables
+for their search paths (see explanation of @code{--search-paths} below).
+Any missing or possibly incorrect environment variable definitions are
+reported here.
+
+@item --install-from-expression=@var{exp}
+@itemx -e @var{exp}
+Install the package @var{exp} evaluates to.
+
+@var{exp} must be a Scheme expression that evaluates to a @code{<package>}
+object.  This option is notably useful to disambiguate between same-named
+variants of a package, with expressions such as @code{(@@ (gnu packages
+base) guile-final)}.
+
+Note that this option installs the first output of the specified package,
+which may be insufficient when needing a specific output of a
+multiple-output package.
+
+@item --install-from-file=@var{file}
+@itemx -f @var{file}
+Install the package that the code within @var{file} evaluates to.
+
+As an example, @var{file} might contain a definition like this
+(@pxref{Définition des paquets}):
+
+@example
+@verbatiminclude package-hello.scm
+@end example
+
+Developers may find it useful to include such a @file{guix.scm} file in the
+root of their project source tree that can be used to test development
+snapshots and create reproducible development environments (@pxref{Invoquer guix environment}).
+
+@item --remove=@var{package} @dots{}
+@itemx -r @var{package} @dots{}
+Remove the specified @var{package}s.
+
+As for @code{--install}, each @var{package} may specify a version number
+and/or output name in addition to the package name.  For instance, @code{-r
+glibc:debug} would remove the @code{debug} output of @code{glibc}.
+
+@item --upgrade[=@var{regexp} @dots{}]
+@itemx -u [@var{regexp} @dots{}]
+@cindex upgrading packages
+Upgrade all the installed packages.  If one or more @var{regexp}s are
+specified, upgrade only installed packages whose name matches a
+@var{regexp}.  Also see the @code{--do-not-upgrade} option below.
+
+Note that this upgrades package to the latest version of packages found in
+the distribution currently installed.  To update your distribution, you
+should regularly run @command{guix pull} (@pxref{Invoquer guix pull}).
+
+@item --do-not-upgrade[=@var{regexp} @dots{}]
+When used together with the @code{--upgrade} option, do @emph{not} upgrade
+any packages whose name matches a @var{regexp}.  For example, to upgrade all
+packages in the current profile except those containing the substring
+``emacs'':
+
+@example
+$ guix package --upgrade . --do-not-upgrade emacs
+@end example
+
+@item @anchor{profile-manifest}--manifest=@var{file}
+@itemx -m @var{file}
+@cindex profile declaration
+@cindex profile manifest
+Create a new generation of the profile from the manifest object returned by
+the Scheme code in @var{file}.
+
+This allows you to @emph{declare} the profile's contents rather than
+constructing it through a sequence of @code{--install} and similar
+commands.  The advantage is that @var{file} can be put under version
+control, copied to different machines to reproduce the same profile, and so
+on.
+
+@c FIXME: Add reference to (guix profile) documentation when available.
+@var{file} must return a @dfn{manifest} object, which is roughly a list of
+packages:
+
+@findex packages->manifest
+@example
+(use-package-modules guile emacs)
+
+(packages->manifest
+ (list emacs
+       guile-2.0
+       ;; Use a specific package output.
+       (list guile-2.0 "debug")))
+@end example
+
+@findex specifications->manifest
+In this example we have to know which modules define the @code{emacs} and
+@code{guile-2.0} variables to provide the right @code{use-package-modules}
+line, which can be cumbersome.  We can instead provide regular package
+specifications and let @code{specifications->manifest} look up the
+corresponding package objects, like this:
+
+@example
+(specifications->manifest
+ '("emacs" "guile@@2.2" "guile@@2.2:debug"))
+@end example
+
+@item --roll-back
+@cindex rolling back
+@cindex undoing transactions
+@cindex transactions, undoing
+Roll back to the previous @dfn{generation} of the profile---i.e., undo the
+last transaction.
+
+When combined with options such as @code{--install}, roll back occurs before
+any other actions.
+
+When rolling back from the first generation that actually contains installed
+packages, the profile is made to point to the @dfn{zeroth generation}, which
+contains no files apart from its own metadata.
+
+After having rolled back, installing, removing, or upgrading packages
+overwrites previous future generations.  Thus, the history of the
+generations in a profile is always linear.
+
+@item --switch-generation=@var{pattern}
+@itemx -S @var{pattern}
+@cindex generations
+Switch to a particular generation defined by @var{pattern}.
+
+@var{pattern} may be either a generation number or a number prefixed with
+``+'' or ``-''.  The latter means: move forward/backward by a specified
+number of generations.  For example, if you want to return to the latest
+generation after @code{--roll-back}, use @code{--switch-generation=+1}.
+
+The difference between @code{--roll-back} and @code{--switch-generation=-1}
+is that @code{--switch-generation} will not make a zeroth generation, so if
+a specified generation does not exist, the current generation will not be
+changed.
+
+@item --search-paths[=@var{kind}]
+@cindex search paths
+Report environment variable definitions, in Bash syntax, that may be needed
+in order to use the set of installed packages.  These environment variables
+are used to specify @dfn{search paths} for files used by some of the
+installed packages.
+
+For example, GCC needs the @code{CPATH} and @code{LIBRARY_PATH} environment
+variables to be defined so it can look for headers and libraries in the
+user's profile (@pxref{Environment Variables,,, gcc, Using the GNU Compiler
+Collection (GCC)}).  If GCC and, say, the C library are installed in the
+profile, then @code{--search-paths} will suggest setting these variables to
+@code{@var{profile}/include} and @code{@var{profile}/lib}, respectively.
+
+The typical use case is to define these environment variables in the shell:
+
+@example
+$ eval `guix package --search-paths`
+@end example
+
+@var{kind} may be one of @code{exact}, @code{prefix}, or @code{suffix},
+meaning that the returned environment variable definitions will either be
+exact settings, or prefixes or suffixes of the current value of these
+variables.  When omitted, @var{kind} defaults to @code{exact}.
+
+This option can also be used to compute the @emph{combined} search paths of
+several profiles.  Consider this example:
+
+@example
+$ guix package -p foo -i guile
+$ guix package -p bar -i guile-json
+$ guix package -p foo -p bar --search-paths
+@end example
+
+The last command above reports about the @code{GUILE_LOAD_PATH} variable,
+even though, taken individually, neither @file{foo} nor @file{bar} would
+lead to that recommendation.
+
+
+@item --profile=@var{profile}
+@itemx -p @var{profile}
+Use @var{profile} instead of the user's default profile.
+
+@cindex collisions, in a profile
+@cindex colliding packages in profiles
+@cindex profile collisions
+@item --allow-collisions
+Allow colliding packages in the new profile.  Use at your own risk!
+
+By default, @command{guix package} reports as an error @dfn{collisions} in
+the profile.  Collisions happen when two or more different versions or
+variants of a given package end up in the profile.
+
+@item --verbose
+Produce verbose output.  In particular, emit the build log of the
+environment on the standard error port.
+
+@item --bootstrap
+Use the bootstrap Guile to build the profile.  This option is only useful to
+distribution developers.
+
+@end table
+
+In addition to these actions, @command{guix package} supports the following
+options to query the current state of a profile, or the availability of
+packages:
+
+@table @option
+
+@item --search=@var{regexp}
+@itemx -s @var{regexp}
+@cindex searching for packages
+List the available packages whose name, synopsis, or description matches
+@var{regexp}, sorted by relevance.  Print all the metadata of matching
+packages in @code{recutils} format (@pxref{Top, GNU recutils databases,,
+recutils, GNU recutils manual}).
+
+This allows specific fields to be extracted using the @command{recsel}
+command, for instance:
+
+@example
+$ guix package -s malloc | recsel -p name,version,relevance
+name: jemalloc
+version: 4.5.0
+relevance: 6
+
+name: glibc
+version: 2.25
+relevance: 1
+
+name: libgc
+version: 7.6.0
+relevance: 1
+@end example
+
+Similarly, to show the name of all the packages available under the terms of
+the GNU@tie{}LGPL version 3:
+
+@example
+$ guix package -s "" | recsel -p name -e 'license ~ "LGPL 3"'
+name: elfutils
+
+name: gmp
+@dots{}
+@end example
+
+It is also possible to refine search results using several @code{-s} flags.
+For example, the following command returns a list of board games:
+
+@example
+$ guix package -s '\<board\>' -s game | recsel -p name
+name: gnubg
+@dots{}
+@end example
+
+If we were to omit @code{-s game}, we would also get software packages that
+deal with printed circuit boards; removing the angle brackets around
+@code{board} would further add packages that have to do with keyboards.
+
+And now for a more elaborate example.  The following command searches for
+cryptographic libraries, filters out Haskell, Perl, Python, and Ruby
+libraries, and prints the name and synopsis of the matching packages:
+
+@example
+$ guix package -s crypto -s library | \
+    recsel -e '! (name ~ "^(ghc|perl|python|ruby)")' -p name,synopsis
+@end example
+
+@noindent
+@xref{Selection Expressions,,, recutils, GNU recutils manual}, for more
+information on @dfn{selection expressions} for @code{recsel -e}.
+
+@item --show=@var{package}
+Show details about @var{package}, taken from the list of available packages,
+in @code{recutils} format (@pxref{Top, GNU recutils databases,, recutils,
+GNU recutils manual}).
+
+@example
+$ guix package --show=python | recsel -p name,version
+name: python
+version: 2.7.6
+
+name: python
+version: 3.3.5
+@end example
+
+You may also specify the full name of a package to only get details about a
+specific version of it:
+@example
+$ guix package --show=python@@3.4 | recsel -p name,version
+name: python
+version: 3.4.3
+@end example
+
+
+
+@item --list-installed[=@var{regexp}]
+@itemx -I [@var{regexp}]
+List the currently installed packages in the specified profile, with the
+most recently installed packages shown last.  When @var{regexp} is
+specified, list only installed packages whose name matches @var{regexp}.
+
+For each installed package, print the following items, separated by tabs:
+the package name, its version string, the part of the package that is
+installed (for instance, @code{out} for the default output, @code{include}
+for its headers, etc.), and the path of this package in the store.
+
+@item --list-available[=@var{regexp}]
+@itemx -A [@var{regexp}]
+Liste les paquets actuellement disponibles dans la distribution pour ce
+système (@pxref{Distribution GNU}). Lorsque @var{regexp} est spécifié, liste
+uniquement les paquets dont le nom correspond à @var{regexp}.
+
+For each package, print the following items separated by tabs: its name, its
+version string, the parts of the package (@pxref{Des paquets avec plusieurs résultats}), and the source location of its definition.
+
+@item --list-generations[=@var{pattern}]
+@itemx -l [@var{pattern}]
+@cindex generations
+Return a list of generations along with their creation dates; for each
+generation, show the installed packages, with the most recently installed
+packages shown last.  Note that the zeroth generation is never shown.
+
+For each installed package, print the following items, separated by tabs:
+the name of a package, its version string, the part of the package that is
+installed (@pxref{Des paquets avec plusieurs résultats}), and the location of this
+package in the store.
+
+When @var{pattern} is used, the command returns only matching generations.
+Valid patterns include:
+
+@itemize
+@item @emph{Integers and comma-separated integers}.  Both patterns denote
+generation numbers.  For instance, @code{--list-generations=1} returns the
+first one.
+
+And @code{--list-generations=1,8,2} outputs three generations in the
+specified order.  Neither spaces nor trailing commas are allowed.
+
+@item @emph{Ranges}.  @code{--list-generations=2..9} prints the
+specified generations and everything in between.  Note that the start of a
+range must be smaller than its end.
+
+It is also possible to omit the endpoint.  For example,
+@code{--list-generations=2..}, returns all generations starting from the
+second one.
+
+@item @emph{Durations}.  You can also get the last @emph{N}@tie{}days, weeks,
+or months by passing an integer along with the first letter of the
+duration.  For example, @code{--list-generations=20d} lists generations that
+are up to 20 days old.
+@end itemize
+
+@item --delete-generations[=@var{pattern}]
+@itemx -d [@var{pattern}]
+When @var{pattern} is omitted, delete all generations except the current
+one.
+
+This command accepts the same patterns as @option{--list-generations}.  When
+@var{pattern} is specified, delete the matching generations.  When
+@var{pattern} specifies a duration, generations @emph{older} than the
+specified duration match.  For instance, @code{--delete-generations=1m}
+deletes generations that are more than one month old.
+
+If the current generation matches, it is @emph{not} deleted.  Also, the
+zeroth generation is never deleted.
+
+Note that deleting generations prevents rolling back to them.  Consequently,
+this command must be used with care.
+
+@end table
+
+Finally, since @command{guix package} may actually start build processes, it
+supports all the common build options (@pxref{Options de construction communes}).  It
+also supports package transformation options, such as @option{--with-source}
+(@pxref{Options de transformation de paquets}).  However, note that package
+transformations are lost when upgrading; to preserve transformations across
+upgrades, you should define your own package variant in a Guile module and
+add it to @code{GUIX_PACKAGE_PATH} (@pxref{Définition des paquets}).

+@node Substituts

+
+@cindex substitutes
+@cindex pre-built binaries
+Guix supports transparent source/binary deployment, which means that it can
+either build things locally, or download pre-built items from a server, or
+both.  We call these pre-built items @dfn{substitutes}---they are
+substitutes for local build results.  In many cases, downloading a
+substitute is much faster than building things locally.
+
+Substitutes can be anything resulting from a derivation build
+(@pxref{Dérivations}).  Of course, in the common case, they are pre-built
+package binaries, but source tarballs, for instance, which also result from

+@cindex hydra
+@cindex build farm
+The @code{mirror.hydra.gnu.org} server is a front-end to an official build
+farm that builds packages from Guix continuously for some architectures, and
+makes them available as substitutes.  This is the default source of
+substitutes; it can be overridden by passing the @option{--substitute-urls}
+option either to @command{guix-daemon} (@pxref{daemon-substitute-urls,,
+@code{guix-daemon --substitute-urls}})  or to client tools such as
+@command{guix package} (@pxref{client-substitute-urls,, client
+@option{--substitute-urls} option}).
+
+Substitute URLs can be either HTTP or HTTPS.  HTTPS is recommended because
+communications are encrypted; conversely, using HTTP makes all
+communications visible to an eavesdropper, who could use the information
+gathered to determine, for instance, whether your system has unpatched
+security vulnerabilities.
+
+Substitutes from the official build farm are enabled by default when using
+the Guix System Distribution (@pxref{Distribution GNU}).  However, they are
+disabled by default when using Guix on a foreign distribution, unless you
+have explicitly enabled them via one of the recommended installation steps
+(@pxref{Installation}).  The following paragraphs describe how to enable or
+disable substitutes for the official build farm; the same procedure can also
+be used to enable substitutes for any other substitute server.
+
+@node Autoriser un serveur de substituts
+@subsection Autoriser un serveur de substituts

+@cindex security
+@cindex substitutes, authorization thereof
+@cindex access control list (ACL), for substitutes
+@cindex ACL (access control list), for substitutes
+To allow Guix to download substitutes from @code{hydra.gnu.org} or a mirror
+thereof, you must add its public key to the access control list (ACL) of
+archive imports, using the @command{guix archive} command (@pxref{Invoquer guix archive}).  Doing so implies that you trust @code{hydra.gnu.org} to not
+be compromised and to serve genuine substitutes.
+
+The public key for @code{hydra.gnu.org} is installed along with Guix, in
+@code{@var{prefix}/share/guix/hydra.gnu.org.pub}, where @var{prefix} is the
+installation prefix of Guix.  If you installed Guix from source, make sure
+you checked the GPG signature of @file{guix-@value{VERSION}.tar.gz}, which
+contains this public key file.  Then, you can run something like this:
+
+@example
+# guix archive --authorize < @var{prefix}/share/guix/hydra.gnu.org.pub
+@end example
+
+@quotation Note
+Similarly, the @file{berlin.guixsd.org.pub} file contains the public key for
+the project's new build farm, reachable at
+@indicateurl{https://berlin.guixsd.org}.
+
+As of this writing @code{berlin.guixsd.org} is being upgraded so it can
+better scale up, but you might want to give it a try.  It is backed by 20
+x86_64/i686 build nodes and may be able to provide substitutes more quickly
+than @code{mirror.hydra.gnu.org}.
+@end quotation
+
+Once this is in place, the output of a command like @code{guix build} should
+change from something like:
+
+@example
+$ guix build emacs --dry-run
+The following derivations would be built:
+   /gnu/store/yr7bnx8xwcayd6j95r2clmkdl1qh688w-emacs-24.3.drv
+   /gnu/store/x8qsh1hlhgjx6cwsjyvybnfv2i37z23w-dbus-1.6.4.tar.gz.drv

+@dots{}
+@end example
+
+@noindent
+to something like:
+
+@example
+$ guix build emacs --dry-run
+112.3 MB would be downloaded:
+   /gnu/store/pk3n22lbq6ydamyymqkkz7i69wiwjiwi-emacs-24.3

+@dots{}
+@end example
+
+@noindent
+This indicates that substitutes from @code{hydra.gnu.org} are usable and
+will be downloaded, when possible, for future builds.
+
+@cindex substitutes, how to disable
+The substitute mechanism can be disabled globally by running
+@code{guix-daemon} with @code{--no-substitutes} (@pxref{Invoquer guix-daemon}).  It can also be disabled temporarily by passing the
+@code{--no-substitutes} option to @command{guix package}, @command{guix
+build}, and other command-line tools.
+
+@node Authentification des substituts
+@subsection Authentification des substituts
+
+@cindex digital signatures
+Guix detects and raises an error when attempting to use a substitute that
+has been tampered with.  Likewise, it ignores substitutes that are not
+signed, or that are not signed by one of the keys listed in the ACL.
+
+There is one exception though: if an unauthorized server provides
+substitutes that are @emph{bit-for-bit identical} to those provided by an
+authorized server, then the unauthorized server becomes eligible for
+downloads.  For example, assume we have chosen two substitute servers with
+this option:
+
+@example
+--substitute-urls="https://a.example.org https://b.example.org"
+@end example
+
+@noindent
+@cindex reproducible builds
+If the ACL contains only the key for @code{b.example.org}, and if
+@code{a.example.org} happens to serve the @emph{exact same} substitutes,
+then Guix will download substitutes from @code{a.example.org} because it
+comes first in the list and can be considered a mirror of
+@code{b.example.org}.  In practice, independent build machines usually
+produce the same binaries, thanks to bit-reproducible builds (see below).
+
+When using HTTPS, the server's X.509 certificate is @emph{not} validated (in
+other words, the server is not authenticated), contrary to what HTTPS
+clients such as Web browsers usually do.  This is because Guix authenticates
+substitute information itself, as explained above, which is what we care
+about (whereas X.509 certificates are about authenticating bindings between
+domain names and public keys.)
+
+@node Paramètres de serveur mandataire
+@subsection Paramètres de serveur mandataire
+
+@vindex http_proxy
+Substitutes are downloaded over HTTP or HTTPS.  The @code{http_proxy}
+environment variable can be set in the environment of @command{guix-daemon}
+and is honored for downloads of substitutes.  Note that the value of
+@code{http_proxy} in the environment where @command{guix build},
+@command{guix package}, and other client commands are run has
+@emph{absolutely no effect}.
+
+@node Échec de substitution
+@subsection Échec de substitution
+
+Even when a substitute for a derivation is available, sometimes the
+substitution attempt will fail.  This can happen for a variety of reasons:
+the substitute server might be offline, the substitute may recently have
+been deleted, the connection might have been interrupted, etc.
+
+When substitutes are enabled and a substitute for a derivation is available,
+but the substitution attempt fails, Guix will attempt to build the
+derivation locally depending on whether or not @code{--fallback} was given
+(@pxref{fallback-option,, common build option @code{--fallback}}).
+Specifically, if @code{--fallback} was omitted, then no local build will be
+performed, and the derivation is considered to have failed.  However, if
+@code{--fallback} was given, then Guix will attempt to build the derivation
+locally, and the success or failure of the derivation depends on the success
+or failure of the local build.  Note that when substitutes are disabled or
+no substitute is available for the derivation in question, a local build
+will @emph{always} be performed, regardless of whether or not
+@code{--fallback} was given.
+
+To get an idea of how many substitutes are available right now, you can try
+running the @command{guix weather} command (@pxref{Invoquer guix weather}).
+This command provides statistics on the substitutes provided by a server.
+
+@node De la confiance en des binaires

+
+@cindex trust, of pre-built binaries
+Today, each individual's control over their own computing is at the mercy of
+institutions, corporations, and groups with enough power and determination
+to subvert the computing infrastructure and exploit its weaknesses.  While
+using @code{hydra.gnu.org} substitutes can be convenient, we encourage users
+to also build on their own, or even run their own build farm, such that
+@code{hydra.gnu.org} is less of an interesting target.  One way to help is
+by publishing the software you build using @command{guix publish} so that
+others have one more choice of server to download substitutes from
+(@pxref{Invoquer guix publish}).
+
+Guix has the foundations to maximize build reproducibility
+(@pxref{Fonctionnalités}).  In most cases, independent builds of a given package or
+derivation should yield bit-identical results.  Thus, through a diverse set
+of independent package builds, we can strengthen the integrity of our
+systems.  The @command{guix challenge} command aims to help users assess
+substitute servers, and to assist developers in finding out about
+non-deterministic package builds (@pxref{Invoquer guix challenge}).
+Similarly, the @option{--check} option of @command{guix build} allows users
+to check whether previously-installed substitutes are genuine by rebuilding
+them locally (@pxref{build-check, @command{guix build --check}}).
+
+In the future, we want Guix to have support to publish and retrieve binaries
+to/from other users, in a peer-to-peer fashion.  If you would like to
+discuss this project, join us on @email{guix-devel@@gnu.org}.

+@cindex multiple-output packages
+@cindex package outputs
+@cindex outputs
+
+Often, packages defined in Guix have a single @dfn{output}---i.e., the
+source package leads to exactly one directory in the store.  When running
+@command{guix package -i glibc}, one installs the default output of the GNU
+libc package; the default output is called @code{out}, but its name can be
+omitted as shown in this command.  In this particular case, the default
+output of @code{glibc} contains all the C header files, shared libraries,
+static libraries, Info documentation, and other supporting files.
+
+Sometimes it is more appropriate to separate the various types of files
+produced from a single source package into separate outputs.  For instance,
+the GLib C library (used by GTK+ and related packages)  installs more than
+20 MiB of reference documentation as HTML pages.  To save space for users
+who do not need it, the documentation goes to a separate output, called
+@code{doc}.  To install the main GLib output, which contains everything but
+the documentation, one would run:
+
+@example
+guix package -i glib
+@end example
+
+@cindex documentation
+The command to install its documentation is:
+
+@example
+guix package -i glib:doc
+@end example
+
+Some packages install programs with different ``dependency footprints''.
+For instance, the WordNet package installs both command-line tools and
+graphical user interfaces (GUIs).  The former depend solely on the C
+library, whereas the latter depend on Tcl/Tk and the underlying X
+libraries.  In this case, we leave the command-line tools in the default
+output, whereas the GUIs are in a separate output.  This allows users who do
+not need the GUIs to save space.  The @command{guix size} command can help
+find out about such situations (@pxref{Invoquer guix size}).  @command{guix
+graph} can also be helpful (@pxref{Invoquer guix graph}).
+
+There are several such multiple-output packages in the GNU distribution.
+Other conventional output names include @code{lib} for libraries and
+possibly header files, @code{bin} for stand-alone programs, and @code{debug}
+for debugging information (@pxref{Installer les fichiers de débogage}).  The outputs
+of a packages are listed in the third column of the output of @command{guix
+package --list-available} (@pxref{Invoquer guix package}).

+@node Invoquer guix gc
+@section Invoking @command{guix gc}
+
+@cindex garbage collector
+@cindex disk space
+Packages that are installed, but not used, may be @dfn{garbage-collected}.
+The @command{guix gc} command allows users to explicitly run the garbage
+collector to reclaim space from the @file{/gnu/store} directory.  It is the
+@emph{only} way to remove files from @file{/gnu/store}---removing files or
+directories manually may break it beyond repair!
+
+@cindex GC roots
+@cindex garbage collector roots
+The garbage collector has a set of known @dfn{roots}: any file under
+@file{/gnu/store} reachable from a root is considered @dfn{live} and cannot
+be deleted; any other file is considered @dfn{dead} and may be deleted.  The
+set of garbage collector roots (``GC roots'' for short)  includes default
+user profiles; by default, the symlinks under @file{/var/guix/gcroots}
+represent these GC roots.  New GC roots can be added with @command{guix
+build --root}, for example (@pxref{Invoquer guix build}).
+
+Prior to running @code{guix gc --collect-garbage} to make space, it is often
+useful to remove old generations from user profiles; that way, old package
+builds referenced by those generations can be reclaimed.  This is achieved
+by running @code{guix package --delete-generations} (@pxref{Invoquer guix package}).
+
+Our recommendation is to run a garbage collection periodically, or when you
+are short on disk space.  For instance, to guarantee that at least 5@tie{}GB
+are available on your disk, simply run:
+
+@example
+guix gc -F 5G
+@end example
+
+It is perfectly safe to run as a non-interactive periodic job
+(@pxref{Scheduled Job Execution}, for how to set up such a job on GuixSD).
+Running @command{guix gc} with no arguments will collect as much garbage as
+it can, but that is often inconvenient: you may find yourself having to
+rebuild or re-download software that is ``dead'' from the GC viewpoint but
+that is necessary to build other pieces of software---e.g., the compiler
+tool chain.
+
+The @command{guix gc} command has three modes of operation: it can be used
+to garbage-collect any dead files (the default), to delete specific files
+(the @code{--delete} option), to print garbage-collector information, or for
+more advanced queries.  The garbage collection options are as follows:
+
+@table @code
+@item --collect-garbage[=@var{min}]
+@itemx -C [@var{min}]
+Collect garbage---i.e., unreachable @file{/gnu/store} files and
+sub-directories.  This is the default operation when no option is specified.
+
+When @var{min} is given, stop once @var{min} bytes have been collected.
+@var{min} may be a number of bytes, or it may include a unit as a suffix,
+such as @code{MiB} for mebibytes and @code{GB} for gigabytes (@pxref{Block
+size, size specifications,, coreutils, GNU Coreutils}).
+
+When @var{min} is omitted, collect all the garbage.
+
+@item --free-space=@var{free}
+@itemx -F @var{free}
+Collect garbage until @var{free} space is available under @file{/gnu/store},
+if possible; @var{free} denotes storage space, such as @code{500MiB}, as
+described above.
+
+When @var{free} or more is already available in @file{/gnu/store}, do
+nothing and exit immediately.
+
+@item --delete
+@itemx -d
+Attempt to delete all the store files and directories specified as
+arguments.  This fails if some of the files are not in the store, or if they
+are still live.
+
+@item --list-failures
+List store items corresponding to cached build failures.
+
+This prints nothing unless the daemon was started with
+@option{--cache-failures} (@pxref{Invoquer guix-daemon,
+@option{--cache-failures}}).
+
+@item --clear-failures
+Remove the specified store items from the failed-build cache.
+
+Again, this option only makes sense when the daemon is started with
+@option{--cache-failures}.  Otherwise, it does nothing.
+
+@item --list-dead
+Show the list of dead files and directories still present in the
+store---i.e., files and directories no longer reachable from any root.
+
+@item --list-live
+Show the list of live store files and directories.
+
+@end table
+
+In addition, the references among existing store files can be queried:
+
+@table @code
+
+@item --references
+@itemx --referrers
+@cindex package dependencies
+List the references (respectively, the referrers) of store files given as
+arguments.
+
+@item --requisites
+@itemx -R
+@cindex closure
+List the requisites of the store files passed as arguments.  Requisites
+include the store files themselves, their references, and the references of
+these, recursively.  In other words, the returned list is the
+@dfn{transitive closure} of the store files.
+
+@xref{Invoquer guix size}, for a tool to profile the size of the closure of
+an element.  @xref{Invoquer guix graph}, for a tool to visualize the graph
+of references.
+
+@item --derivers
+@cindex derivation
+Return the derivation(s) leading to the given store items
+(@pxref{Dérivations}).
+
+For example, this command:
+
+@example
+guix gc --derivers `guix package -I ^emacs$ | cut -f4`
+@end example
+
+@noindent
+returns the @file{.drv} file(s) leading to the @code{emacs} package
+installed in your profile.
+
+Note that there may be zero matching @file{.drv} files, for instance because
+these files have been garbage-collected.  There can also be more than one
+matching @file{.drv} due to fixed-output derivations.
+@end table
+
+Lastly, the following options allow you to check the integrity of the store
+and to control disk usage.
+
+@table @option
+
+@item --verify[=@var{options}]
+@cindex integrity, of the store
+@cindex integrity checking
+Verify the integrity of the store.
+
+By default, make sure that all the store items marked as valid in the
+database of the daemon actually exist in @file{/gnu/store}.
+
+When provided, @var{options} must be a comma-separated list containing one
+or more of @code{contents} and @code{repair}.
+
+When passing @option{--verify=contents}, the daemon computes the content
+hash of each store item and compares it against its hash in the database.
+Hash mismatches are reported as data corruptions.  Because it traverses
+@emph{all the files in the store}, this command can take a long time,
+especially on systems with a slow disk drive.
+
+@cindex repairing the store
+@cindex corruption, recovering from
+Utiliser @option{--verify=repair} ou @option{--verify=contents,repair} fait

+connaissez exactement quelle entrée est corrompue consiste à lancer
+@command{guix build --repair} (@pxref{Invoquer guix build}).
+
+@item --optimize
+@cindex deduplication
+Optimize the store by hard-linking identical files---this is
+@dfn{deduplication}.
+
+The daemon performs deduplication after each successful build or archive
+import, unless it was started with @code{--disable-deduplication}
+(@pxref{Invoquer guix-daemon, @code{--disable-deduplication}}).  Thus, this

+@cindex pack
+@cindex bundle
+@cindex application bundle
+@cindex software bundle
+The @command{guix pack} command creates a shrink-wrapped @dfn{pack} or
+@dfn{software bundle}: it creates a tarball or some other archive containing
+the binaries of the software you're interested in, and all its
+dependencies.  The resulting archive can be used on any machine that does
+not have Guix, and people can run the exact same binaries as those you have
+with Guix.  The pack itself is created in a bit-reproducible fashion, so
+anyone can verify that it really contains the build results that you pretend
+to be shipping.
+
+For example, to create a bundle containing Guile, Emacs, Geiser, and all
+their dependencies, you can run:
+
+@example
+$ guix pack guile emacs geiser
+@dots{}
+/gnu/store/@dots{}-pack.tar.gz
+@end example
+
+The result here is a tarball containing a @file{/gnu/store} directory with
+all the relevant packages.  The resulting tarball contains a @dfn{profile}
+with the three packages of interest; the profile is the same as would be
+created by @command{guix package -i}.  It is this mechanism that is used to
+create Guix's own standalone binary tarball (@pxref{Installation binaire}).
+
+Users of this pack would have to run
+@file{/gnu/store/@dots{}-profile/bin/guile} to run Guile, which you may find
+inconvenient.  To work around it, you can create, say, a @file{/opt/gnu/bin}
+symlink to the profile:
+
+@example
+guix pack -S /opt/gnu/bin=bin guile emacs geiser
+@end example
+
+@noindent
+That way, users can happily type @file{/opt/gnu/bin/guile} and enjoy.
+
+Alternatively, you can produce a pack in the Docker image format using the
+following command:
+
+@example
+guix pack -f docker guile emacs geiser
+@end example
+
+@noindent
+The result is a tarball that can be passed to the @command{docker load}
+command.  See the
+@uref{https://docs.docker.com/engine/reference/commandline/load/, Docker
+documentation} for more information.
+
+Several command-line options allow you to customize your pack:

+Cross-build for @var{triplet}, which must be a valid GNU triplet, such as
+@code{"mips64el-linux-gnu"} (@pxref{Specifying target triplets, GNU
+configuration triplets,, autoconf, Autoconf}).
+
+@item --compression=@var{tool}
+@itemx -C @var{tool}
+Compress the resulting tarball using @var{tool}---one of @code{gzip},
+@code{bzip2}, @code{xz}, @code{lzip}, or @code{none} for no compression.
+
+@item --symlink=@var{spec}
+@itemx -S @var{spec}
+Add the symlinks specified by @var{spec} to the pack.  This option can
+appear several times.
+
+@var{spec} has the form @code{@var{source}=@var{target}}, where @var{source}
+is the symlink that will be created and @var{target} is the symlink target.
+
+For instance, @code{-S /opt/gnu/bin=bin} creates a @file{/opt/gnu/bin}
+symlink pointing to the @file{bin} sub-directory of the profile.
+
+@item --localstatedir
+Include the ``local state directory'', @file{/var/guix}, in the resulting
+pack.
+
+@file{/var/guix} contains the store database (@pxref{Le dépôt}) as well as
+garbage-collector roots (@pxref{Invoquer guix gc}).  Providing it in the
+pack means that the store is ``complete'' and manageable by Guix; not
+providing it pack means that the store is ``dead'': items cannot be added to
+it or removed from it after extraction of the pack.
+
+One use case for this is the Guix self-contained binary tarball
+(@pxref{Installation binaire}).
+
+@item --bootstrap
+Use the bootstrap binaries to build the pack.  This option is only useful to
+Guix developers.
+@end table
+
+In addition, @command{guix pack} supports all the common build options
+(@pxref{Options de construction communes}) and all the package transformation options
+(@pxref{Options de transformation de paquets}).
+
+
+@node Invoquer guix archive
+@section Invoking @command{guix archive}
+
+@cindex @command{guix archive}
+@cindex archive
+The @command{guix archive} command allows users to @dfn{export} files from
+the store into a single archive, and to later @dfn{import} them on a machine
+that runs Guix.  In particular, it allows store files to be transferred from
+one machine to the store on another machine.
+
+@quotation Note
+If you're looking for a way to produce archives in a format suitable for
+tools other than Guix, @pxref{Invoquer guix pack}.
+@end quotation
+
+@cindex exporting store items
+To export store files as an archive to standard output, run:
+
+@example
+guix archive --export @var{options} @var{specifications}...
+@end example
+
+@var{specifications} may be either store file names or package
+specifications, as for @command{guix package} (@pxref{Invoquer guix package}).  For instance, the following command creates an archive
+containing the @code{gui} output of the @code{git} package and the main
+output of @code{emacs}:
+
+@example
+guix archive --export git:gui /gnu/store/...-emacs-24.3 > great.nar
+@end example
+
+If the specified packages are not built yet, @command{guix archive}
+automatically builds them.  The build process may be controlled with the
+common build options (@pxref{Options de construction communes}).
+
+To transfer the @code{emacs} package to a machine connected over SSH, one
+would run:
+
+@example
+guix archive --export -r emacs | ssh the-machine guix archive --import
+@end example
+
+@noindent
+Similarly, a complete user profile may be transferred from one machine to
+another like this:
+
+@example
+guix archive --export -r $(readlink -f ~/.guix-profile) | \
+  ssh the-machine guix-archive --import
+@end example
+
+@noindent
+However, note that, in both examples, all of @code{emacs} and the profile as
+well as all of their dependencies are transferred (due to @code{-r}),
+regardless of what is already available in the store on the target machine.
+The @code{--missing} option can help figure out which items are missing from
+the target store.  The @command{guix copy} command simplifies and optimizes
+this whole process, so this is probably what you should use in this case
+(@pxref{Invoquer guix copy}).
+
+@cindex nar, archive format
+@cindex normalized archive (nar)
+Archives are stored in the ``normalized archive'' or ``nar'' format, which
+is comparable in spirit to `tar', but with differences that make it more
+appropriate for our purposes.  First, rather than recording all Unix
+metadata for each file, the nar format only mentions the file type (regular,
+directory, or symbolic link); Unix permissions and owner/group are
+dismissed.  Second, the order in which directory entries are stored always
+follows the order of file names according to the C locale collation order.
+This makes archive production fully deterministic.
+
+@c FIXME: Add xref to daemon doc about signatures.
+When exporting, the daemon digitally signs the contents of the archive, and
+that digital signature is appended.  When importing, the daemon verifies the
+signature and rejects the import in case of an invalid signature or if the
+signing key is not authorized.
+
+The main options are:
+
+@table @code
+@item --export
+Export the specified store files or packages (see below.)  Write the
+resulting archive to the standard output.
+
+Dependencies are @emph{not} included in the output, unless
+@code{--recursive} is passed.
+
+@item -r
+@itemx --recursive
+When combined with @code{--export}, this instructs @command{guix archive} to
+include dependencies of the given items in the archive.  Thus, the resulting
+archive is self-contained: it contains the closure of the exported store
+items.
+
+@item --import
+Read an archive from the standard input, and import the files listed therein
+into the store.  Abort if the archive has an invalid digital signature, or
+if it is signed by a public key not among the authorized keys (see
+@code{--authorize} below.)
+
+@item --missing
+Read a list of store file names from the standard input, one per line, and
+write on the standard output the subset of these files missing from the
+store.
+
+@item --generate-key[=@var{parameters}]
+@cindex signing, archives
+Generate a new key pair for the daemon.  This is a prerequisite before
+archives can be exported with @code{--export}.  Note that this operation
+usually takes time, because it needs to gather enough entropy to generate
+the key pair.
+
+The generated key pair is typically stored under @file{/etc/guix}, in
+@file{signing-key.pub} (public key) and @file{signing-key.sec} (private key,
+which must be kept secret.)  When @var{parameters} is omitted, an ECDSA key
+using the Ed25519 curve is generated, or, for Libgcrypt versions before
+1.6.0, it is a 4096-bit RSA key.  Alternatively, @var{parameters} can
+specify @code{genkey} parameters suitable for Libgcrypt (@pxref{General
+public-key related Functions, @code{gcry_pk_genkey},, gcrypt, The Libgcrypt
+Reference Manual}).
+
+@item --authorize
+@cindex authorizing, archives
+Authorize imports signed by the public key passed on standard input.  The
+public key must be in ``s-expression advanced format''---i.e., the same
+format as the @file{signing-key.pub} file.
+
+The list of authorized keys is kept in the human-editable file
+@file{/etc/guix/acl}.  The file contains
+@url{http://people.csail.mit.edu/rivest/Sexp.txt, ``advanced-format
+s-expressions''} and is structured as an access-control list in the
+@url{http://theworld.com/~cme/spki.txt, Simple Public-Key Infrastructure
+(SPKI)}.
+
+@item --extract=@var{directory}
+@itemx -x @var{directory}
+Lit une archive à un seul élément telle que servie par un serveur de
+substituts (@pxref{Substituts}) et l'extrait dans @var{directory}. C'est une
+opération de bas niveau requise seulement dans de rares cas d'usage ; voir
+plus loin.
+
+For example, the following command extracts the substitute for Emacs served
+by @code{hydra.gnu.org} to @file{/tmp/emacs}:
+
+@example
+$ wget -O - \
+  https://hydra.gnu.org/nar/@dots{}-emacs-24.5 \
+  | bunzip2 | guix archive -x /tmp/emacs
+@end example
+
+Single-item archives are different from multiple-item archives produced by
+@command{guix archive --export}; they contain a single store item, and they
+do @emph{not} embed a signature.  Thus this operation does @emph{no}
+signature verification and its output should be considered unsafe.
+
+The primary purpose of this operation is to facilitate inspection of archive
+contents coming from possibly untrusted substitute servers.

+@node Interface de programmation
+@chapter Interface de programmation
+
+GNU Guix provides several Scheme programming interfaces (APIs) to define,
+build, and query packages.  The first interface allows users to write
+high-level package definitions.  These definitions refer to familiar
+packaging concepts, such as the name and version of a package, its build
+system, and its dependencies.  These definitions can then be turned into
+concrete build actions.
+
+Build actions are performed by the Guix daemon, on behalf of users.  In a
+standard setup, the daemon has write access to the store---the
+@file{/gnu/store} directory---whereas users do not.  The recommended setup
+also has the daemon perform builds in chroots, under a specific build users,
+to minimize interference with the rest of the system.
+
+@cindex derivation
+Lower-level APIs are available to interact with the daemon and the store.
+To instruct the daemon to perform a build action, users actually provide it
+with a @dfn{derivation}.  A derivation is a low-level representation of the
+build actions to be taken, and the environment in which they should
+occur---derivations are to package definitions what assembly is to C
+programs.  The term ``derivation'' comes from the fact that build results
+@emph{derive} from them.
+
+This chapter describes all these APIs in turn, starting from high-level
+package definitions.

+@node Définition des paquets
+@section Définition des paquets
+
+The high-level interface to package definitions is implemented in the
+@code{(guix packages)} and @code{(guix build-system)} modules.  As an
+example, the package definition, or @dfn{recipe}, for the GNU Hello package
+looks like this:
+
+@example
+(define-module (gnu packages hello)
+  #:use-module (guix packages)
+  #:use-module (guix download)
+  #:use-module (guix build-system gnu)
+  #:use-module (guix licenses)
+  #:use-module (gnu packages gawk))
+
+(define-public hello
+  (package
+    (name "hello")
+    (version "2.10")
+    (source (origin
+              (method url-fetch)
+              (uri (string-append "mirror://gnu/hello/hello-" version
+                                  ".tar.gz"))
+              (sha256
+               (base32
+                "0ssi1wpaf7plaswqqjwigppsg5fyh99vdlb9kzl7c9lng89ndq1i"))))
+    (build-system gnu-build-system)
+    (arguments '(#:configure-flags '("--enable-silent-rules")))
+    (inputs `(("gawk" ,gawk)))
+    (synopsis "Hello, GNU world: An example GNU package")
+    (description "Guess what GNU Hello prints!")
+    (home-page "http://www.gnu.org/software/hello/")
+    (license gpl3+)))
+@end example
+
+@noindent
+Without being a Scheme expert, the reader may have guessed the meaning of
+the various fields here.  This expression binds the variable @code{hello} to
+a @code{<package>} object, which is essentially a record (@pxref{SRFI-9,
+Scheme records,, guile, GNU Guile Reference Manual}).  This package object
+can be inspected using procedures found in the @code{(guix packages)}
+module; for instance, @code{(package-name hello)}
+returns---surprise!---@code{"hello"}.
+
+With luck, you may be able to import part or all of the definition of the
+package you are interested in from another repository, using the @code{guix
+import} command (@pxref{Invoquer guix import}).
+
+In the example above, @var{hello} is defined in a module of its own,
+@code{(gnu packages hello)}.  Technically, this is not strictly necessary,
+but it is convenient to do so: all the packages defined in modules under
+@code{(gnu packages @dots{})} are automatically known to the command-line
+tools (@pxref{Modules de paquets}).
+
+There are a few points worth noting in the above package definition:
+
+@itemize
+@item
+The @code{source} field of the package is an @code{<origin>} object
+(@pxref{Référence d'origine}, for the complete reference).  Here, the
+@code{url-fetch} method from @code{(guix download)} is used, meaning that
+the source is a file to be downloaded over FTP or HTTP.
+
+The @code{mirror://gnu} prefix instructs @code{url-fetch} to use one of the
+GNU mirrors defined in @code{(guix download)}.
+
+The @code{sha256} field specifies the expected SHA256 hash of the file being
+downloaded.  It is mandatory, and allows Guix to check the integrity of the
+file.  The @code{(base32 @dots{})} form introduces the base32 representation
+of the hash.  You can obtain this information with @code{guix download}
+(@pxref{Invoquer guix download}) and @code{guix hash} (@pxref{Invoquer guix hash}).
+
+@cindex patches
+When needed, the @code{origin} form can also have a @code{patches} field
+listing patches to be applied, and a @code{snippet} field giving a Scheme
+expression to modify the source code.
+
+@item
+@cindex GNU Build System
+The @code{build-system} field specifies the procedure to build the package
+(@pxref{Systèmes de construction}).  Here, @var{gnu-build-system} represents the
+familiar GNU Build System, where packages may be configured, built, and
+installed with the usual @code{./configure && make && make check && make
+install} command sequence.
+
+@item
+The @code{arguments} field specifies options for the build system
+(@pxref{Systèmes de construction}).  Here it is interpreted by @var{gnu-build-system}
+as a request run @file{configure} with the @code{--enable-silent-rules}
+flag.
+
+@cindex quote
+@cindex quoting
+@findex '
+@findex quote
+What about these quote (@code{'}) characters? They are Scheme syntax to
+introduce a literal list; @code{'} is synonymous with @code{quote}.
+@xref{Expression Syntax, quoting,, guile, GNU Guile Reference Manual}, for
+details.  Here the value of the @code{arguments} field is a list of
+arguments passed to the build system down the road, as with @code{apply}
+(@pxref{Fly Evaluation, @code{apply},, guile, GNU Guile Reference Manual}).
+
+The hash-colon (@code{#:}) sequence defines a Scheme @dfn{keyword}
+(@pxref{Keywords,,, guile, GNU Guile Reference Manual}), and
+@code{#:configure-flags} is a keyword used to pass a keyword argument to the
+build system (@pxref{Coding With Keywords,,, guile, GNU Guile Reference
+Manual}).
+
+@item
+The @code{inputs} field specifies inputs to the build process---i.e.,
+build-time or run-time dependencies of the package.  Here, we define an
+input called @code{"gawk"} whose value is that of the @var{gawk} variable;
+@var{gawk} is itself bound to a @code{<package>} object.
+
+@cindex backquote (quasiquote)
+@findex `
+@findex quasiquote
+@cindex comma (unquote)
+@findex ,
+@findex unquote
+@findex ,@@
+@findex unquote-splicing
+Again, @code{`} (a backquote, synonymous with @code{quasiquote}) allows us
+to introduce a literal list in the @code{inputs} field, while @code{,} (a
+comma, synonymous with @code{unquote}) allows us to insert a value in that
+list (@pxref{Expression Syntax, unquote,, guile, GNU Guile Reference
+Manual}).
+
+Note that GCC, Coreutils, Bash, and other essential tools do not need to be
+specified as inputs here.  Instead, @var{gnu-build-system} takes care of
+ensuring that they are present (@pxref{Systèmes de construction}).
+
+However, any other dependencies need to be specified in the @code{inputs}
+field.  Any dependency not specified here will simply be unavailable to the
+build process, possibly leading to a build failure.
+@end itemize
+
+@xref{Référence de paquet}, for a full description of possible fields.
+
+Once a package definition is in place, the package may actually be built
+using the @code{guix build} command-line tool (@pxref{Invoquer guix build}),
+troubleshooting any build failures you encounter (@pxref{Débogage des échecs de construction}).  You can easily jump back to the package definition using the
+@command{guix edit} command (@pxref{Invoquer guix edit}).  @xref{Consignes d'empaquetage}, for more information on how to test package definitions, and
+@ref{Invoquer guix lint}, for information on how to check a definition for
+style conformance.
+@vindex GUIX_PACKAGE_PATH
+Lastly, @pxref{Modules de paquets}, for information on how to extend the
+distribution by adding your own package definitions to
+@code{GUIX_PACKAGE_PATH}.
+
+Finally, updating the package definition to a new upstream version can be
+partly automated by the @command{guix refresh} command (@pxref{Invoquer guix refresh}).
+
+Behind the scenes, a derivation corresponding to the @code{<package>} object
+is first computed by the @code{package-derivation} procedure.  That
+derivation is stored in a @code{.drv} file under @file{/gnu/store}.  The
+build actions it prescribes may then be realized by using the
+@code{build-derivations} procedure (@pxref{Le dépôt}).
+
+@deffn {Scheme Procedure} package-derivation @var{store} @var{package} [@var{system}]
+Return the @code{<derivation>} object of @var{package} for @var{system}
+(@pxref{Dérivations}).
+
+@var{package} must be a valid @code{<package>} object, and @var{system} must
+be a string denoting the target system type---e.g., @code{"x86_64-linux"}
+for an x86_64 Linux-based GNU system.  @var{store} must be a connection to
+the daemon, which operates on the store (@pxref{Le dépôt}).
+@end deffn
+
+@noindent
+@cindex cross-compilation
+Similarly, it is possible to compute a derivation that cross-builds a
+package for some other system:
+
+@deffn {Scheme Procedure} package-cross-derivation @var{store} @
+            @var{package} @var{target} [@var{system}] Return the @code{<derivation>}
+object of @var{package} cross-built from @var{system} to @var{target}.
+
+@var{target} must be a valid GNU triplet denoting the target hardware and
+operating system, such as @code{"mips64el-linux-gnu"} (@pxref{Configuration
+Names, GNU configuration triplets,, configure, GNU Configure and Build
+System}).
+@end deffn
+
+@cindex package transformations
+@cindex input rewriting
+@cindex dependency tree rewriting
+Packages can be manipulated in arbitrary ways.  An example of a useful
+transformation is @dfn{input rewriting}, whereby the dependency tree of a
+package is rewritten by replacing specific inputs by others:
+
+@deffn {Scheme Procedure} package-input-rewriting @var{replacements} @
+           [@var{rewrite-name}] Return a procedure that, when passed a package,
+replaces its direct and indirect dependencies (but not its implicit inputs)
+according to @var{replacements}.  @var{replacements} is a list of package
+pairs; the first element of each pair is the package to replace, and the
+second one is the replacement.
+
+Optionally, @var{rewrite-name} is a one-argument procedure that takes the
+name of a package and returns its new name after rewrite.
+@end deffn
+
+@noindent
+Consider this example:
+
+@example
+(define libressl-instead-of-openssl
+  ;; This is a procedure to replace OPENSSL by LIBRESSL,
+  ;; recursively.
+  (package-input-rewriting `((,openssl . ,libressl))))
+
+(define git-with-libressl
+  (libressl-instead-of-openssl git))
+@end example
+
+@noindent
+Here we first define a rewriting procedure that replaces @var{openssl} with
+@var{libressl}.  Then we use it to define a @dfn{variant} of the @var{git}
+package that uses @var{libressl} instead of @var{openssl}.  This is exactly
+what the @option{--with-input} command-line option does (@pxref{Options de transformation de paquets, @option{--with-input}}).
+
+A more generic procedure to rewrite a package dependency graph is
+@code{package-mapping}: it supports arbitrary changes to nodes in the graph.
+
+@deffn {Scheme Procedure} package-mapping @var{proc} [@var{cut?}]
+Return a procedure that, given a package, applies @var{proc} to all the
+packages depended on and returns the resulting package.  The procedure stops
+recursion when @var{cut?} returns true for a given package.

+This is the data type representing a package recipe.
+

+@item @code{name}
+The name of the package, as a string.
+
+@item @code{version}
+The version of the package, as a string.
+
+@item @code{source}
+An object telling how the source code for the package should be acquired.
+Most of the time, this is an @code{origin} object, which denotes a file
+fetched from the Internet (@pxref{Référence d'origine}).  It can also be any

+@itemx @code{native-inputs} (default: @code{'()})
+@itemx @code{propagated-inputs} (default: @code{'()})
+@cindex inputs, of packages
+These fields list dependencies of the package.  Each one is a list of
+tuples, where each tuple has a label for the input (a string) as its first
+element, a package, origin, or derivation as its second element, and
+optionally the name of the output thereof that should be used, which
+defaults to @code{"out"} (@pxref{Des paquets avec plusieurs résultats}, for more
+on package outputs).  For example, the list below specifies three inputs:
+
+@example
+`(("libffi" ,libffi)
+  ("libunistring" ,libunistring)
+  ("glib:bin" ,glib "bin"))  ;the "bin" output of Glib
+@end example
+
+@cindex cross compilation, package dependencies
+The distinction between @code{native-inputs} and @code{inputs} is necessary
+when considering cross-compilation.  When cross-compiling, dependencies
+listed in @code{inputs} are built for the @emph{target} architecture;
+conversely, dependencies listed in @code{native-inputs} are built for the
+architecture of the @emph{build} machine.
+
+@code{native-inputs} is typically used to list tools needed at build time,
+but not at run time, such as Autoconf, Automake, pkg-config, Gettext, or
+Bison.  @command{guix lint} can report likely mistakes in this area
+(@pxref{Invoquer guix lint}).
+
+@anchor{package-propagated-inputs}
+Lastly, @code{propagated-inputs} is similar to @code{inputs}, but the
+specified packages will be automatically installed alongside the package
+they belong to (@pxref{package-cmd-propagated-inputs, @command{guix
+package}}, for information on how @command{guix package} deals with
+propagated inputs.)
+
+For example this is necessary when a C/C++ library needs headers of another
+library to compile, or when a pkg-config file refers to another one @i{via}
+its @code{Requires} field.
+
+Another example where @code{propagated-inputs} is useful is for languages
+that lack a facility to record the run-time search path akin to the
+@code{RUNPATH} of ELF files; this includes Guile, Python, Perl, and more.
+To ensure that libraries written in those languages can find library code
+they depend on at run time, run-time dependencies must be listed in
+@code{propagated-inputs} rather than @code{inputs}.
+
+@item @code{self-native-input?} (default: @code{#f})
+This is a Boolean field telling whether the package should use itself as a
+native input when cross-compiling.
+
+@item @code{outputs} (default: @code{'("out")})
+The list of output names of the package.  @xref{Des paquets avec plusieurs résultats}, for typical uses of additional outputs.
+
+@item @code{native-search-paths} (default: @code{'()})
+@itemx @code{search-paths} (default: @code{'()})
+A list of @code{search-path-specification} objects describing search-path
+environment variables honored by the package.
+
+@item @code{replacement} (default: @code{#f})
+This must be either @code{#f} or a package object that will be used as a

+@code{architecture-kernel}, for example @code{"x86_64-linux"}.
+
+@item @code{maintainers} (default: @code{'()})
+The list of maintainers of the package, as @code{maintainer} objects.
+
+@item @code{location} (default: source location of the @code{package} form)
+The source location of the package.  It is useful to override this when

+@node Référence d'origine
+@subsection @code{origin} Reference
+
+This section summarizes all the options available in @code{origin}
+declarations (@pxref{Définition des paquets}).
+
+@deftp {Data Type} origin
+This is the data type representing a source code origin.
+
+@table @asis
+@item @code{uri}
+An object containing the URI of the source.  The object type depends on the
+@code{method} (see below).  For example, when using the @var{url-fetch}
+method of @code{(guix download)}, the valid @code{uri} values are: a URL
+represented as a string, or a list thereof.
+
+@item @code{method}
+A procedure that handles the URI.
+
+Examples include:
+
+@table @asis
+@item @var{url-fetch} from @code{(guix download)}
+download a file from the HTTP, HTTPS, or FTP URL specified in the @code{uri}
+field;
+
+@vindex git-fetch
+@item @var{git-fetch} from @code{(guix git-download)}
+clone the Git version control repository, and check out the revision
+specified in the @code{uri} field as a @code{git-reference} object; a
+@code{git-reference} looks like this:
+
+@example
+(git-reference
+  (url "git://git.debian.org/git/pkg-shadow/shadow")
+  (commit "v4.1.5.1"))
+@end example
+@end table
+
+@item @code{sha256}
+A bytevector containing the SHA-256 hash of the source.  Typically the
+@code{base32} form is used here to generate the bytevector from a base-32
+string.
+
+You can obtain this information using @code{guix download} (@pxref{Invoquer guix download}) or @code{guix hash} (@pxref{Invoquer guix hash}).
+
+@item @code{file-name} (default: @code{#f})
+The file name under which the source code should be saved.  When this is
+@code{#f}, a sensible default value will be used in most cases.  In case the
+source is fetched from a URL, the file name from the URL will be used.  For
+version control checkouts, it is recommended to provide the file name
+explicitly because the default is not very descriptive.
+
+@item @code{patches} (default: @code{'()})
+A list of file names, origins, or file-like objects (@pxref{G-Expressions,
+file-like objects}) pointing to patches to be applied to the source.
+
+This list of patches must be unconditional.  In particular, it cannot depend
+on the value of @code{%current-system} or @code{%current-target-system}.
+
+@item @code{snippet} (default: @code{#f})
+A G-expression (@pxref{G-Expressions}) or S-expression that will be run in
+the source directory.  This is a convenient way to modify the source,
+sometimes more convenient than a patch.
+
+@item @code{patch-flags} (default: @code{'("-p1")})
+A list of command-line flags that should be passed to the @code{patch}
+command.
+
+@item @code{patch-inputs} (default: @code{#f})
+Input packages or derivations to the patching process.  When this is
+@code{#f}, the usual set of inputs necessary for patching are provided, such
+as GNU@tie{}Patch.
+
+@item @code{modules} (default: @code{'()})
+A list of Guile modules that should be loaded during the patching process
+and while running the code in the @code{snippet} field.
+
+@item @code{patch-guile} (default: @code{#f})
+The Guile package that should be used in the patching process.  When this is
+@code{#f}, a sensible default is used.

+@cindex build system
+Each package definition specifies a @dfn{build system} and arguments for
+that build system (@pxref{Définition des paquets}).  This @code{build-system}
+field represents the build procedure of the package, as well as implicit
+dependencies of that build procedure.
+
+Build systems are @code{<build-system>} objects.  The interface to create
+and manipulate them is provided by the @code{(guix build-system)} module,
+and actual build systems are exported by specific modules.
+
+@cindex bag (low-level package representation)
+Under the hood, build systems first compile package objects to @dfn{bags}.
+A @dfn{bag} is like a package, but with less ornamentation---in other words,
+a bag is a lower-level representation of a package, which includes all the
+inputs of that package, including some that were implicitly added by the
+build system.  This intermediate representation is then compiled to a
+derivation (@pxref{Dérivations}).
+
+Build systems accept an optional list of @dfn{arguments}.  In package
+definitions, these are passed @i{via} the @code{arguments} field
+(@pxref{Définition des paquets}).  They are typically keyword arguments
+(@pxref{Optional Arguments, keyword arguments in Guile,, guile, GNU Guile
+Reference Manual}).  The value of these arguments is usually evaluated in
+the @dfn{build stratum}---i.e., by a Guile process launched by the daemon
+(@pxref{Dérivations}).
+
+The main build system is @var{gnu-build-system}, which implements the
+standard build procedure for GNU and many other packages.  It is provided by
+the @code{(guix build-system gnu)} module.
+
+@defvr {Scheme Variable} gnu-build-system
+@var{gnu-build-system} represents the GNU Build System, and variants thereof
+(@pxref{Configuration, configuration and makefile conventions,, standards,
+GNU Coding Standards}).
+
+@cindex build phases
+In a nutshell, packages using it are configured, built, and installed with
+the usual @code{./configure && make && make check && make install} command
+sequence.  In practice, a few additional steps are often needed.  All these
+steps are split up in separate @dfn{phases}, notably@footnote{Please see the
+@code{(guix build gnu-build-system)} modules for more details about the
+build phases.}:
+
+@table @code
+@item unpack
+Unpack the source tarball, and change the current directory to the extracted
+source tree.  If the source is actually a directory, copy it to the build
+tree, and enter that directory.
+
+@item patch-source-shebangs
+Patch shebangs encountered in source files so they refer to the right store
+file names.  For instance, this changes @code{#!/bin/sh} to
+@code{#!/gnu/store/@dots{}-bash-4.3/bin/sh}.
+
+@item configure
+Run the @file{configure} script with a number of default options, such as
+@code{--prefix=/gnu/store/@dots{}}, as well as the options specified by the
+@code{#:configure-flags} argument.
+
+@item build
+Run @code{make} with the list of flags specified with @code{#:make-flags}.
+If the @code{#:parallel-build?} argument is true (the default), build with
+@code{make -j}.
+
+@item check
+Run @code{make check}, or some other target specified with
+@code{#:test-target}, unless @code{#:tests? #f} is passed.  If the
+@code{#:parallel-tests?} argument is true (the default), run @code{make
+check -j}.
+
+@item install
+Run @code{make install} with the flags listed in @code{#:make-flags}.
+
+@item patch-shebangs
+Patch shebangs on the installed executable files.
+
+@item strip
+Strip debugging symbols from ELF files (unless @code{#:strip-binaries?} is
+false), copying them to the @code{debug} output when available
+(@pxref{Installer les fichiers de débogage}).
+@end table
+
+@vindex %standard-phases
+The build-side module @code{(guix build gnu-build-system)} defines
+@var{%standard-phases} as the default list of build phases.
+@var{%standard-phases} is a list of symbol/procedure pairs, where the
+procedure implements the actual phase.
+
+The list of phases used for a particular package can be changed with the
+@code{#:phases} parameter.  For instance, passing:
+
+@example
+#:phases (modify-phases %standard-phases (delete 'configure))
+@end example
+
+means that all the phases described above will be used, except the
+@code{configure} phase.
+
+In addition, this build system ensures that the ``standard'' environment for
+GNU packages is available.  This includes tools such as GCC, libc,
+Coreutils, Bash, Make, Diffutils, grep, and sed (see the @code{(guix
+build-system gnu)} module for a complete list).  We call these the
+@dfn{implicit inputs} of a package, because package definitions do not have
+to mention them.
+@end defvr
+
+Other @code{<build-system>} objects are defined to support other conventions
+and tools used by free software packages.  They inherit most of
+@var{gnu-build-system}, and differ mainly in the set of inputs implicitly
+added to the build process, and in the list of phases executed.  Some of
+these build systems are listed below.
+
+@defvr {Scheme Variable} ant-build-system
+This variable is exported by @code{(guix build-system ant)}.  It implements
+the build procedure for Java packages that can be built with
+@url{http://ant.apache.org/, Ant build tool}.
+
+It adds both @code{ant} and the @dfn{Java Development Kit} (JDK) as provided
+by the @code{icedtea} package to the set of inputs.  Different packages can
+be specified with the @code{#:ant} and @code{#:jdk} parameters,
+respectively.
+
+When the original package does not provide a suitable Ant build file, the
+parameter @code{#:jar-name} can be used to generate a minimal Ant build file
+@file{build.xml} with tasks to build the specified jar archive.  In this
+case the parameter @code{#:source-dir} can be used to specify the source
+sub-directory, defaulting to ``src''.
+
+The @code{#:main-class} parameter can be used with the minimal ant buildfile
+to specify the main class of the resulting jar.  This makes the jar file
+executable.  The @code{#:test-include} parameter can be used to specify the
+list of junit tests to run. It defaults to @code{(list "**/*Test.java")}.
+The @code{#:test-exclude} can be used to disable some tests. It defaults to
+@code{(list "**/Abstract*.java")}, because abstract classes cannot be run as
+tests.
+
+The parameter @code{#:build-target} can be used to specify the Ant task that
+should be run during the @code{build} phase.  By default the ``jar'' task
+will be run.
+
+@end defvr
+
+@defvr {Scheme Variable} asdf-build-system/source
+@defvrx {Scheme Variable} asdf-build-system/sbcl
+@defvrx {Scheme Variable} asdf-build-system/ecl
+
+These variables, exported by @code{(guix build-system asdf)}, implement
+build procedures for Common Lisp packages using
+@url{https://common-lisp.net/project/asdf/, ``ASDF''}. ASDF is a system
+definition facility for Common Lisp programs and libraries.
+
+The @code{asdf-build-system/source} system installs the packages in source
+form, and can be loaded using any common lisp implementation, via ASDF.  The
+others, such as @code{asdf-build-system/sbcl}, install binary systems in the
+format which a particular implementation understands.  These build systems
+can also be used to produce executable programs, or lisp images which
+contain a set of packages pre-loaded.
+
+The build system uses naming conventions.  For binary packages, the package
+name should be prefixed with the lisp implementation, such as @code{sbcl-}
+for @code{asdf-build-system/sbcl}.
+
+Additionally, the corresponding source package should be labeled using the
+same convention as python packages (see @ref{Modules python}), using the
+@code{cl-} prefix.
+
+For binary packages, each system should be defined as a Guix package.  If
+one package @code{origin} contains several systems, package variants can be
+created in order to build all the systems.  Source packages, which use
+@code{asdf-build-system/source}, may contain several systems.
+
+In order to create executable programs and images, the build-side procedures
+@code{build-program} and @code{build-image} can be used.  They should be
+called in a build phase after the @code{create-symlinks} phase, so that the
+system which was just built can be used within the resulting image.
+@code{build-program} requires a list of Common Lisp expressions to be passed
+as the @code{#:entry-program} argument.
+
+If the system is not defined within its own @code{.asd} file of the same
+name, then the @code{#:asd-file} parameter should be used to specify which
+file the system is defined in.  Furthermore, if the package defines a system
+for its tests in a separate file, it will be loaded before the tests are run
+if it is specified by the @code{#:test-asd-file} parameter.  If it is not
+set, the files @code{<system>-tests.asd}, @code{<system>-test.asd},
+@code{tests.asd}, and @code{test.asd} will be tried if they exist.
+
+If for some reason the package must be named in a different way than the
+naming conventions suggest, the @code{#:asd-system-name} parameter can be
+used to specify the name of the system.
+
+@end defvr
+
+@defvr {Scheme Variable} cargo-build-system
+@cindex Rust programming language
+@cindex Cargo (Rust build system)
+This variable is exported by @code{(guix build-system cargo)}.  It supports
+builds of packages using Cargo, the build tool of the
+@uref{https://www.rust-lang.org, Rust programming language}.
+
+In its @code{configure} phase, this build system replaces dependencies
+specified in the @file{Carto.toml} file with inputs to the Guix package.
+The @code{install} phase installs the binaries, and it also installs the
+source code and @file{Cargo.toml} file.
+@end defvr
+
+@defvr {Scheme Variable} cmake-build-system
+This variable is exported by @code{(guix build-system cmake)}.  It
+implements the build procedure for packages using the
+@url{http://www.cmake.org, CMake build tool}.
+
+It automatically adds the @code{cmake} package to the set of inputs.  Which
+package is used can be specified with the @code{#:cmake} parameter.
+
+The @code{#:configure-flags} parameter is taken as a list of flags passed to
+the @command{cmake} command.  The @code{#:build-type} parameter specifies in
+abstract terms the flags passed to the compiler; it defaults to
+@code{"RelWithDebInfo"} (short for ``release mode with debugging
+information''), which roughly means that code is compiled with @code{-O2
+-g}, as is the case for Autoconf-based packages by default.
+@end defvr
+
+@defvr {Scheme Variable} go-build-system
+This variable is exported by @code{(guix build-system go)}.  It implements a
+build procedure for Go packages using the standard
+@url{https://golang.org/cmd/go/#hdr-Compile_packages_and_dependencies, Go
+build mechanisms}.
+
+The user is expected to provide a value for the key @code{#:import-path}
+and, in some cases, @code{#:unpack-path}.  The
+@url{https://golang.org/doc/code.html#ImportPaths, import path} corresponds
+to the file system path expected by the package's build scripts and any
+referring packages, and provides a unique way to refer to a Go package.  It
+is typically based on a combination of the package source code's remote URI
+and file system hierarchy structure.  In some cases, you will need to unpack
+the package's source code to a different directory structure than the one
+indicated by the import path, and @code{#:unpack-path} should be used in
+such cases.
+
+Packages that provide Go libraries should be installed along with their
+source code.  The key @code{#:install-source?}, which defaults to @code{#t},
+controls whether or not the source code is installed.  It can be set to
+@code{#f} for packages that only provide executable files.
+@end defvr
+
+@defvr {Scheme Variable} glib-or-gtk-build-system
+This variable is exported by @code{(guix build-system glib-or-gtk)}.  It is
+intended for use with packages making use of GLib or GTK+.
+
+This build system adds the following two phases to the ones defined by
+@var{gnu-build-system}:
+
+@table @code
+@item glib-or-gtk-wrap
+The phase @code{glib-or-gtk-wrap} ensures that programs in @file{bin/} are
+able to find GLib ``schemas'' and
+@uref{https://developer.gnome.org/gtk3/stable/gtk-running.html, GTK+
+modules}.  This is achieved by wrapping the programs in launch scripts that
+appropriately set the @code{XDG_DATA_DIRS} and @code{GTK_PATH} environment
+variables.
+
+It is possible to exclude specific package outputs from that wrapping
+process by listing their names in the
+@code{#:glib-or-gtk-wrap-excluded-outputs} parameter.  This is useful when
+an output is known not to contain any GLib or GTK+ binaries, and where
+wrapping would gratuitously add a dependency of that output on GLib and
+GTK+.
+
+@item glib-or-gtk-compile-schemas
+The phase @code{glib-or-gtk-compile-schemas} makes sure that all
+@uref{https://developer.gnome.org/gio/stable/glib-compile-schemas.html,
+GSettings schemas} of GLib are compiled.  Compilation is performed by the
+@command{glib-compile-schemas} program.  It is provided by the package
+@code{glib:bin} which is automatically imported by the build system.  The
+@code{glib} package providing @command{glib-compile-schemas} can be
+specified with the @code{#:glib} parameter.
+@end table
+
+Both phases are executed after the @code{install} phase.
+@end defvr
+
+@defvr {Scheme Variable} minify-build-system
+This variable is exported by @code{(guix build-system minify)}.  It
+implements a minification procedure for simple JavaScript packages.
+
+It adds @code{uglify-js} to the set of inputs and uses it to compress all
+JavaScript files in the @file{src} directory.  A different minifier package
+can be specified with the @code{#:uglify-js} parameter, but it is expected
+that the package writes the minified code to the standard output.
+
+When the input JavaScript files are not all located in the @file{src}
+directory, the parameter @code{#:javascript-files} can be used to specify a
+list of file names to feed to the minifier.
+@end defvr
+
+@defvr {Scheme Variable} ocaml-build-system
+This variable is exported by @code{(guix build-system ocaml)}.  It
+implements a build procedure for @uref{https://ocaml.org, OCaml} packages,
+which consists of choosing the correct set of commands to run for each
+package.  OCaml packages can expect many different commands to be run.  This
+build system will try some of them.
+
+When the package has a @file{setup.ml} file present at the top-level, it
+will run @code{ocaml setup.ml -configure}, @code{ocaml setup.ml -build} and
+@code{ocaml setup.ml -install}.  The build system will assume that this file
+was generated by @uref{http://oasis.forge.ocamlcore.org/, OASIS} and will
+take care of setting the prefix and enabling tests if they are not
+disabled.  You can pass configure and build flags with the
+@code{#:configure-flags} and @code{#:build-flags}.  The @code{#:test-flags}
+key can be passed to change the set of flags used to enable tests.  The
+@code{#:use-make?} key can be used to bypass this system in the build and
+install phases.
+
+When the package has a @file{configure} file, it is assumed that it is a
+hand-made configure script that requires a different argument format than in
+the @code{gnu-build-system}.  You can add more flags with the
+@code{#:configure-flags} key.
+
+When the package has a @file{Makefile} file (or @code{#:use-make?} is
+@code{#t}), it will be used and more flags can be passed to the build and
+install phases with the @code{#:make-flags} key.
+
+Finally, some packages do not have these files and use a somewhat standard
+location for its build system.  In that case, the build system will run
+@code{ocaml pkg/pkg.ml} or @code{ocaml pkg/build.ml} and take care of
+providing the path to the required findlib module.  Additional flags can be
+passed via the @code{#:build-flags} key.  Install is taken care of by
+@command{opam-installer}.  In this case, the @code{opam} package must be
+added to the @code{native-inputs} field of the package definition.
+
+Note that most OCaml packages assume they will be installed in the same
+directory as OCaml, which is not what we want in guix.  In particular, they
+will install @file{.so} files in their module's directory, which is usually
+fine because it is in the OCaml compiler directory.  In guix though, these
+libraries cannot be found and we use @code{CAML_LD_LIBRARY_PATH}.  This
+variable points to @file{lib/ocaml/site-lib/stubslibs} and this is where
+@file{.so} libraries should be installed.
+@end defvr
+
+@defvr {Scheme Variable} python-build-system
+This variable is exported by @code{(guix build-system python)}.  It
+implements the more or less standard build procedure used by Python
+packages, which consists in running @code{python setup.py build} and then
+@code{python setup.py install --prefix=/gnu/store/@dots{}}.
+
+For packages that install stand-alone Python programs under @code{bin/}, it
+takes care of wrapping these programs so that their @code{PYTHONPATH}
+environment variable points to all the Python libraries they depend on.
+
+Which Python package is used to perform the build can be specified with the
+@code{#:python} parameter.  This is a useful way to force a package to be
+built for a specific version of the Python interpreter, which might be
+necessary if the package is only compatible with a single interpreter
+version.
+
+By default guix calls @code{setup.py} under control of @code{setuptools},
+much like @command{pip} does.  Some packages are not compatible with
+setuptools (and pip), thus you can disable this by setting the
+@code{#:use-setuptools} parameter to @code{#f}.
+@end defvr
+
+@defvr {Scheme Variable} perl-build-system
+This variable is exported by @code{(guix build-system perl)}.  It implements
+the standard build procedure for Perl packages, which either consists in
+running @code{perl Build.PL --prefix=/gnu/store/@dots{}}, followed by
+@code{Build} and @code{Build install}; or in running @code{perl Makefile.PL
+PREFIX=/gnu/store/@dots{}}, followed by @code{make} and @code{make install},
+depending on which of @code{Build.PL} or @code{Makefile.PL} is present in
+the package distribution.  Preference is given to the former if both
+@code{Build.PL} and @code{Makefile.PL} exist in the package distribution.
+This preference can be reversed by specifying @code{#t} for the
+@code{#:make-maker?} parameter.
+
+The initial @code{perl Makefile.PL} or @code{perl Build.PL} invocation
+passes flags specified by the @code{#:make-maker-flags} or
+@code{#:module-build-flags} parameter, respectively.
+
+Which Perl package is used can be specified with @code{#:perl}.
+@end defvr
+
+@defvr {Scheme Variable} r-build-system
+This variable is exported by @code{(guix build-system r)}.  It implements
+the build procedure used by @uref{http://r-project.org, R} packages, which
+essentially is little more than running @code{R CMD INSTALL
+--library=/gnu/store/@dots{}} in an environment where @code{R_LIBS_SITE}
+contains the paths to all R package inputs.  Tests are run after
+installation using the R function @code{tools::testInstalledPackage}.
+@end defvr
+
+@defvr {Scheme Variable} texlive-build-system
+This variable is exported by @code{(guix build-system texlive)}.  It is used
+to build TeX packages in batch mode with a specified engine.  The build
+system sets the @code{TEXINPUTS} variable to find all TeX source files in
+the inputs.
+
+By default it runs @code{luatex} on all files ending on @code{ins}.  A
+different engine and format can be specified with the @code{#:tex-format}
+argument.  Different build targets can be specified with the
+@code{#:build-targets} argument, which expects a list of file names.  The
+build system adds only @code{texlive-bin} and @code{texlive-latex-base}
+(both from @code{(gnu packages tex}) to the inputs.  Both can be overridden
+with the arguments @code{#:texlive-bin} and @code{#:texlive-latex-base},
+respectively.
+
+The @code{#:tex-directory} parameter tells the build system where to install
+the built files under the texmf tree.
+@end defvr
+
+@defvr {Scheme Variable} ruby-build-system
+This variable is exported by @code{(guix build-system ruby)}.  It implements
+the RubyGems build procedure used by Ruby packages, which involves running
+@code{gem build} followed by @code{gem install}.
+
+The @code{source} field of a package that uses this build system typically
+references a gem archive, since this is the format that Ruby developers use
+when releasing their software.  The build system unpacks the gem archive,
+potentially patches the source, runs the test suite, repackages the gem, and
+installs it.  Additionally, directories and tarballs may be referenced to
+allow building unreleased gems from Git or a traditional source release
+tarball.
+
+Which Ruby package is used can be specified with the @code{#:ruby}
+parameter.  A list of additional flags to be passed to the @command{gem}
+command can be specified with the @code{#:gem-flags} parameter.
+@end defvr
+
+@defvr {Scheme Variable} waf-build-system
+This variable is exported by @code{(guix build-system waf)}.  It implements
+a build procedure around the @code{waf} script.  The common
+phases---@code{configure}, @code{build}, and @code{install}---are
+implemented by passing their names as arguments to the @code{waf} script.
+
+The @code{waf} script is executed by the Python interpreter.  Which Python
+package is used to run the script can be specified with the @code{#:python}
+parameter.
+@end defvr
+
+@defvr {Scheme Variable} scons-build-system
+This variable is exported by @code{(guix build-system scons)}.  It
+implements the build procedure used by the SCons software construction
+tool.  This build system runs @code{scons} to build the package, @code{scons
+test} to run tests, and then @code{scons install} to install the package.
+
+Additional flags to be passed to @code{scons} can be specified with the
+@code{#:scons-flags} parameter.  The version of Python used to run SCons can
+be specified by selecting the appropriate SCons package with the
+@code{#:scons} parameter.
+@end defvr
+
+@defvr {Scheme Variable} haskell-build-system
+This variable is exported by @code{(guix build-system haskell)}.  It
+implements the Cabal build procedure used by Haskell packages, which
+involves running @code{runhaskell Setup.hs configure
+--prefix=/gnu/store/@dots{}} and @code{runhaskell Setup.hs build}.  Instead
+of installing the package by running @code{runhaskell Setup.hs install}, to
+avoid trying to register libraries in the read-only compiler store
+directory, the build system uses @code{runhaskell Setup.hs copy}, followed
+by @code{runhaskell Setup.hs register}.  In addition, the build system
+generates the package documentation by running @code{runhaskell Setup.hs
+haddock}, unless @code{#:haddock? #f} is passed.  Optional Haddock
+parameters can be passed with the help of the @code{#:haddock-flags}
+parameter.  If the file @code{Setup.hs} is not found, the build system looks
+for @code{Setup.lhs} instead.

+
+It first creates the @code{@var{package}-autoloads.el} file, then it byte
+compiles all Emacs Lisp files.  Differently from the Emacs packaging system,

+@defvr {Scheme Variable} meson-build-system
+This variable is exported by @code{(guix build-system meson)}.  It
+implements the build procedure for packages that use
+@url{http://mesonbuild.com, Meson} as their build system.
+
+It adds both Meson and @uref{https://ninja-build.org/, Ninja} to the set of
+inputs, and they can be changed with the parameters @code{#:meson} and
+@code{#:ninja} if needed.  The default Meson is @code{meson-for-build},
+which is special because it doesn't clear the @code{RUNPATH} of binaries and
+libraries when they are installed.
+
+This build system is an extension of @var{gnu-build-system}, but with the
+following phases changed to some specific for Meson:
+
+@table @code
+
+@item configure
+The phase runs @code{meson} with the flags specified in
+@code{#:configure-flags}.  The flag @code{--build-type} is always set to
+@code{plain} unless something else is specified in @code{#:build-type}.
+
+@item build
+The phase runs @code{ninja} to build the package in parallel by default, but
+this can be changed with @code{#:parallel-build?}.
+
+@item check
+The phase runs @code{ninja} with the target specified in
+@code{#:test-target}, which is @code{"test"} by default.
+
+@item install
+The phase runs @code{ninja install} and can not be changed.
+@end table
+
+Apart from that, the build system also adds the following phases:
+
+@table @code
+
+@item fix-runpath
+This phase ensures that all binaries can find the libraries they need.  It
+searches for required libraries in subdirectories of the package being
+built, and adds those to @code{RUNPATH} where needed.  It also removes
+references to libraries left over from the build phase by
+@code{meson-for-build}, such as test dependencies, that aren't actually
+required for the program to run.
+
+@item glib-or-gtk-wrap
+This phase is the phase provided by @code{glib-or-gtk-build-system}, and it
+is not enabled by default.  It can be enabled with @code{#:glib-or-gtk?}.
+
+@item glib-or-gtk-compile-schemas
+This phase is the phase provided by @code{glib-or-gtk-build-system}, and it
+is not enabled by default.  It can be enabled with @code{#:glib-or-gtk?}.
+@end table
+@end defvr
+
+Lastly, for packages that do not need anything as sophisticated, a
+``trivial'' build system is provided.  It is trivial in the sense that it
+provides basically no support: it does not pull any implicit inputs, and
+does not have a notion of build phases.
+
+@defvr {Scheme Variable} trivial-build-system
+This variable is exported by @code{(guix build-system trivial)}.
+
+This build system requires a @code{#:builder} argument.  This argument must

+@cindex store items
+@cindex store paths
+
+Conceptually, the @dfn{store} is the place where derivations that have been
+built successfully are stored---by default, @file{/gnu/store}.
+Sub-directories in the store are referred to as @dfn{store items} or
+sometimes @dfn{store paths}.  The store has an associated database that
+contains information such as the store paths referred to by each store path,
+and the list of @emph{valid} store items---results of successful builds.
+This database resides in @file{@var{localstatedir}/guix/db}, where
+@var{localstatedir} is the state directory specified @i{via}
+@option{--localstatedir} at configure time, usually @file{/var}.
+
+The store is @emph{always} accessed by the daemon on behalf of its clients
+(@pxref{Invoquer guix-daemon}).  To manipulate the store, clients connect to
+the daemon over a Unix-domain socket, send requests to it, and read the
+result---these are remote procedure calls, or RPCs.
+
+@quotation Note
+Users must @emph{never} modify files under @file{/gnu/store} directly.  This
+would lead to inconsistencies and break the immutability assumptions of
+Guix's functional model (@pxref{Introduction}).
+
+@xref{Invoquer guix gc, @command{guix gc --verify}}, for information on how
+to check the integrity of the store and attempt recovery from accidental
+modifications.
+@end quotation
+
+The @code{(guix store)} module provides procedures to connect to the daemon,
+and to perform RPCs.  These are described below.  By default,
+@code{open-connection}, and thus all the @command{guix} commands, connect to
+the local daemon or to the URI specified by the @code{GUIX_DAEMON_SOCKET}
+environment variable.
+
+@defvr {Environment Variable} GUIX_DAEMON_SOCKET
+When set, the value of this variable should be a file name or a URI
+designating the daemon endpoint.  When it is a file name, it denotes a
+Unix-domain socket to connect to.  In addition to file names, the supported
+URI schemes are:
+
+@table @code
+@item file
+@itemx unix
+These are for Unix-domain sockets.
+@code{file:///var/guix/daemon-socket/socket} is equivalent to
+@file{/var/guix/daemon-socket/socket}.
+
+@item guix
+@cindex daemon, remote access
+@cindex remote access to the daemon
+@cindex daemon, cluster setup
+@cindex clusters, daemon setup
+These URIs denote connections over TCP/IP, without encryption nor
+authentication of the remote host.  The URI must specify the host name and
+optionally a port number (by default port 44146 is used):
+
+@example
+guix://master.guix.example.org:1234
+@end example
+
+This setup is suitable on local networks, such as clusters, where only
+trusted nodes may connect to the build daemon at
+@code{master.guix.example.org}.
+
+The @code{--listen} option of @command{guix-daemon} can be used to instruct
+it to listen for TCP connections (@pxref{Invoquer guix-daemon,
+@code{--listen}}).
+
+@item ssh
+@cindex SSH access to build daemons
+These URIs allow you to connect to a remote daemon over SSH@footnote{This
+feature requires Guile-SSH (@pxref{Prérequis}).}.  A typical URL might
+look like this:
+
+@example
+ssh://charlie@@guix.example.org:22
+@end example
+
+As for @command{guix copy}, the usual OpenSSH client configuration files are
+honored (@pxref{Invoquer guix copy}).
+@end table
+
+Additional URI schemes may be supported in the future.
+
+@c XXX: Remove this note when the protocol incurs fewer round trips
+@c and when (guix derivations) no longer relies on file system access.

+The ability to connect to remote build daemons is considered experimental as

+@cindex derivations
+Low-level build actions and the environment in which they are performed are
+represented by @dfn{derivations}.  A derivation contains the following
+pieces of information:
+
+@itemize
+@item
+The outputs of the derivation---derivations produce at least one file or
+directory in the store, but may produce more.
+
+@item
+The inputs of the derivations, which may be other derivations or plain files
+in the store (patches, build scripts, etc.)
+
+@item
+The system type targeted by the derivation---e.g., @code{x86_64-linux}.
+
+@item
+The file name of a build script in the store, along with the arguments to be
+passed.
+
+@item
+A list of environment variables to be defined.
+
+@end itemize
+
+@cindex derivation path
+Derivations allow clients of the daemon to communicate build actions to the
+store.  They exist in two forms: as an in-memory representation, both on the
+client- and daemon-side, and as files in the store whose name end in
+@code{.drv}---these files are referred to as @dfn{derivation paths}.
+Derivations paths can be passed to the @code{build-derivations} procedure to
+perform the build actions they prescribe (@pxref{Le dépôt}).
+
+@cindex fixed-output derivations
+Operations such as file downloads and version-control checkouts for which
+the expected content hash is known in advance are modeled as
+@dfn{fixed-output derivations}.  Unlike regular derivations, the outputs of
+a fixed-output derivation are independent of its inputs---e.g., a source
+code download produces the same result regardless of the download method and
+tools being used.
+
+The @code{(guix derivations)} module provides a representation of
+derivations as Scheme objects, along with procedures to create and otherwise
+manipulate derivations.  The lowest-level primitive to create a derivation
+is the @code{derivation} procedure:
+
+@deffn {Scheme Procedure} derivation @var{store} @var{name} @var{builder} @
+  @var{args} [#:outputs '("out")] [#:hash #f] [#:hash-algo #f] @ [#:recursive?
+#f] [#:inputs '()] [#:env-vars '()] @ [#:system (%current-system)]
+[#:references-graphs #f] @ [#:allowed-references #f]
+[#:disallowed-references #f] @ [#:leaked-env-vars #f] [#:local-build? #f] @
+[#:substitutable? #t] Construit une dérivation avec les arguments donnés et
+renvie l'objet @code{<derivation>} obtenu.
+
+When @var{hash} and @var{hash-algo} are given, a @dfn{fixed-output
+derivation} is created---i.e., one whose result is known in advance, such as
+a file download.  If, in addition, @var{recursive?} is true, then that fixed
+output may be an executable file or a directory and @var{hash} must be the
+hash of an archive containing this output.
+
+When @var{references-graphs} is true, it must be a list of file name/store
+path pairs.  In that case, the reference graph of each store path is
+exported in the build environment in the corresponding file, in a simple
+text format.
+
+When @var{allowed-references} is true, it must be a list of store items or
+outputs that the derivation's output may refer to.  Likewise,
+@var{disallowed-references}, if true, must be a list of things the outputs
+may @emph{not} refer to.
+
+When @var{leaked-env-vars} is true, it must be a list of strings denoting
+environment variables that are allowed to ``leak'' from the daemon's
+environment to the build environment.  This is only applicable to
+fixed-output derivations---i.e., when @var{hash} is true.  The main use is
+to allow variables such as @code{http_proxy} to be passed to derivations
+that download files.
+
+When @var{local-build?} is true, declare that the derivation is not a good
+candidate for offloading and should rather be built locally (@pxref{Réglages du délestage du démon}).  This is the case for small derivations where the costs of
+data transfers would outweigh the benefits.
+
+Lorsque que @var{substitutable?} est faux, déclare que les substituts de la
+sortie de la dérivation ne devraient pas être utilisés
+(@pxref{Substituts}). Cela est utile par exemple pour construire des paquets
+qui utilisent des détails du jeu d'instruction du CPU hôte.
+@end deffn

+@noindent
+Here's an example with a shell script as its builder, assuming @var{store}
+is an open connection to the daemon, and @var{bash} points to a Bash
+executable in the store:

+             (guix store)

+                           "echo hello world > $out\n" '())))
+  (derivation store "foo"

+              #:env-vars '(("HOME" . "/homeless"))))
+@result{} #<derivation /gnu/store/@dots{}-foo.drv => /gnu/store/@dots{}-foo>
+@end lisp
+
+As can be guessed, this primitive is cumbersome to use directly.  A better
+approach is to write build scripts in Scheme, of course! The best course of
+action for that is to write the build code as a ``G-expression'', and to
+pass it to @code{gexp->derivation}.  For more information,
+@pxref{G-Expressions}.
+
+Once upon a time, @code{gexp->derivation} did not exist and constructing
+derivations with build code written in Scheme was achieved with
+@code{build-expression->derivation}, documented below.  This procedure is
+now deprecated in favor of the much nicer @code{gexp->derivation}.
+
+@deffn {Scheme Procedure} build-expression->derivation @var{store} @

+#f] [#:substitutable? #t] [#:guile-for-build #f] Return a derivation that
+executes Scheme expression @var{exp} as a builder for derivation
+@var{name}.  @var{inputs} must be a list of @code{(name drv-path sub-drv)}
+tuples; when @var{sub-drv} is omitted, @code{"out"} is assumed.
+@var{modules} is a list of names of Guile modules from the current search
+path to be copied in the store, compiled, and made available in the load
+path during the execution of @var{exp}---e.g., @code{((guix build utils)
+(guix build gnu-build-system))}.
+
+@var{exp} is evaluated in an environment where @code{%outputs} is bound to a
+list of output/path pairs, and where @code{%build-inputs} is bound to a list
+of string/output-path pairs made from @var{inputs}.  Optionally,
+@var{env-vars} is a list of string pairs specifying the name and value of
+environment variables visible to the builder.  The builder terminates by
+passing the result of @var{exp} to @code{exit}; thus, when @var{exp} returns
+@code{#f}, the build is considered to have failed.
+
+@var{exp} is built using @var{guile-for-build} (a derivation).  When
+@var{guile-for-build} is omitted or is @code{#f}, the value of the
+@code{%guile-for-build} fluid is used instead.

+@cindex monad
+
+The procedures that operate on the store described in the previous sections
+all take an open connection to the build daemon as their first argument.
+Although the underlying model is functional, they either have side effects
+or depend on the current state of the store.
+
+The former is inconvenient: the connection to the build daemon has to be
+carried around in all those functions, making it impossible to compose
+functions that do not take that parameter with functions that do.  The
+latter can be problematic: since store operations have side effects and/or
+depend on external state, they have to be properly sequenced.
+
+@cindex monadic values
+@cindex monadic functions
+This is where the @code{(guix monads)} module comes in.  This module
+provides a framework for working with @dfn{monads}, and a particularly
+useful monad for our uses, the @dfn{store monad}.  Monads are a construct
+that allows two things: associating ``context'' with values (in our case,
+the context is the store), and building sequences of computations (here
+computations include accesses to the store).  Values in a monad---values
+that carry this additional context---are called @dfn{monadic values};
+procedures that return such values are called @dfn{monadic procedures}.
+
+Consider this ``normal'' procedure:
+
+@example
+(define (sh-symlink store)
+  ;; Return a derivation that symlinks the 'bash' executable.
+  (let* ((drv (package-derivation store bash))
+         (out (derivation->output-path drv))
+         (sh  (string-append out "/bin/bash")))
+    (build-expression->derivation store "sh"
+                                  `(symlink ,sh %output))))
+@end example
+
+Using @code{(guix monads)} and @code{(guix gexp)}, it may be rewritten as a
+monadic function:
+
+@example
+(define (sh-symlink)
+  ;; Same, but return a monadic value.
+  (mlet %store-monad ((drv (package->derivation bash)))
+    (gexp->derivation "sh"
+                      #~(symlink (string-append #$drv "/bin/bash")
+                                 #$output))))
+@end example
+
+There are several things to note in the second version: the @code{store}
+parameter is now implicit and is ``threaded'' in the calls to the
+@code{package->derivation} and @code{gexp->derivation} monadic procedures,
+and the monadic value returned by @code{package->derivation} is @dfn{bound}
+using @code{mlet} instead of plain @code{let}.
+
+As it turns out, the call to @code{package->derivation} can even be omitted
+since it will take place implicitly, as we will see later
+(@pxref{G-Expressions}):
+
+@example
+(define (sh-symlink)
+  (gexp->derivation "sh"
+                    #~(symlink (string-append #$bash "/bin/bash")
+                               #$output)))
+@end example
+
+@c See
+@c <https://syntaxexclamation.wordpress.com/2014/06/26/escaping-continuations/>
+@c for the funny quote.
+Calling the monadic @code{sh-symlink} has no effect.  As someone once said,
+``you exit a monad like you exit a building on fire: by running''.  So, to
+exit the monad and get the desired effect, one must use
+@code{run-with-store}:
+
+@example
+(run-with-store (open-connection) (sh-symlink))
+@result{} /gnu/store/...-sh-symlink
+@end example
+
+Note that the @code{(guix monad-repl)} module extends the Guile REPL with
+new ``meta-commands'' to make it easier to deal with monadic procedures:
+@code{run-in-store}, and @code{enter-store-monad}.  The former is used to
+``run'' a single monadic value through the store:
+
+@example
+scheme@@(guile-user)> ,run-in-store (package->derivation hello)
+$1 = #<derivation /gnu/store/@dots{}-hello-2.9.drv => @dots{}>
+@end example
+
+The latter enters a recursive REPL, where all the return values are
+automatically run through the store:
+
+@example
+scheme@@(guile-user)> ,enter-store-monad
+store-monad@@(guile-user) [1]> (package->derivation hello)
+$2 = #<derivation /gnu/store/@dots{}-hello-2.9.drv => @dots{}>
+store-monad@@(guile-user) [1]> (text-file "foo" "Hello!")
+$3 = "/gnu/store/@dots{}-foo"
+store-monad@@(guile-user) [1]> ,q
+scheme@@(guile-user)>
+@end example
+
+@noindent
+Note that non-monadic values cannot be returned in the @code{store-monad}
+REPL.
+
+The main syntactic forms to deal with monads in general are provided by the
+@code{(guix monads)} module and are described below.
+
+@deffn {Scheme Syntax} with-monad @var{monad} @var{body} ...
+Evaluate any @code{>>=} or @code{return} forms in @var{body} as being in
+@var{monad}.
+@end deffn
+
+@deffn {Scheme Syntax} return @var{val}
+Return a monadic value that encapsulates @var{val}.
+@end deffn
+
+@deffn {Scheme Syntax} >>= @var{mval} @var{mproc} ...
+@dfn{Bind} monadic value @var{mval}, passing its ``contents'' to monadic
+procedures @var{mproc}@dots{}@footnote{This operation is commonly referred
+to as ``bind'', but that name denotes an unrelated procedure in Guile.  Thus
+we use this somewhat cryptic symbol inherited from the Haskell language.}.
+There can be one @var{mproc} or several of them, as in this example:
+
+@example
+(run-with-state
+    (with-monad %state-monad
+      (>>= (return 1)
+           (lambda (x) (return (+ 1 x)))
+           (lambda (x) (return (* 2 x)))))
+  'some-state)
+
+@result{} 4
+@result{} some-state
+@end example
+@end deffn
+
+@deffn {Scheme Syntax} mlet @var{monad} ((@var{var} @var{mval}) ...) @
+       @var{body} ...
+@deffnx {Scheme Syntax} mlet* @var{monad} ((@var{var} @var{mval}) ...) @
+       @var{body} ...  Bind the variables @var{var} to the monadic values
+@var{mval} in @var{body}, which is a sequence of expressions.  As with the
+bind operator, this can be thought of as ``unpacking'' the raw, non-monadic
+value ``contained'' in @var{mval} and making @var{var} refer to that raw,
+non-monadic value within the scope of the @var{body}.  The form (@var{var}
+-> @var{val}) binds @var{var} to the ``normal'' value @var{val}, as per
+@code{let}.  The binding operations occur in sequence from left to right.
+The last expression of @var{body} must be a monadic expression, and its
+result will become the result of the @code{mlet} or @code{mlet*} when run in
+the @var{monad}.
+
+@code{mlet*} is to @code{mlet} what @code{let*} is to @code{let}
+(@pxref{Local Bindings,,, guile, GNU Guile Reference Manual}).
+@end deffn
+
+@deffn {Scheme System} mbegin @var{monad} @var{mexp} ...
+Bind @var{mexp} and the following monadic expressions in sequence, returning
+the result of the last expression.  Every expression in the sequence must be
+a monadic expression.
+
+This is akin to @code{mlet}, except that the return values of the monadic
+expressions are ignored.  In that sense, it is analogous to @code{begin},
+but applied to monadic expressions.
+@end deffn
+
+@deffn {Scheme System} mwhen @var{condition} @var{mexp0} @var{mexp*} ...
+When @var{condition} is true, evaluate the sequence of monadic expressions
+@var{mexp0}..@var{mexp*} as in an @code{mbegin}.  When @var{condition} is
+false, return @code{*unspecified*} in the current monad.  Every expression
+in the sequence must be a monadic expression.
+@end deffn
+
+@deffn {Scheme System} munless @var{condition} @var{mexp0} @var{mexp*} ...

+the sequence must be a monadic expression.
+@end deffn
+
+@cindex state monad
+The @code{(guix monads)} module provides the @dfn{state monad}, which allows
+an additional value---the state---to be @emph{threaded} through monadic
+procedure calls.
+
+@defvr {Scheme Variable} %state-monad
+The state monad.  Procedures in the state monad can access and change the
+state that is threaded.
+
+Consider the example below.  The @code{square} procedure returns a value in
+the state monad.  It returns the square of its argument, but also increments
+the current state value:
+
+@example
+(define (square x)
+  (mlet %state-monad ((count (current-state)))
+    (mbegin %state-monad
+      (set-current-state (+ 1 count))
+      (return (* x x)))))
+
+(run-with-state (sequence %state-monad (map square (iota 3))) 0)
+@result{} (0 1 4)
+@result{} 3
+@end example
+
+When ``run'' through @var{%state-monad}, we obtain that additional state
+value, which is the number of @code{square} calls.
+@end defvr
+
+@deffn {Monadic Procedure} current-state
+Return the current state as a monadic value.
+@end deffn
+
+@deffn {Monadic Procedure} set-current-state @var{value}
+Set the current state to @var{value} and return the previous state as a
+monadic value.
+@end deffn
+
+@deffn {Monadic Procedure} state-push @var{value}
+Push @var{value} to the current state, which is assumed to be a list, and
+return the previous state as a monadic value.
+@end deffn
+
+@deffn {Monadic Procedure} state-pop
+Pop a value from the current state and return it as a monadic value.  The
+state is assumed to be a list.
+@end deffn
+
+@deffn {Scheme Procedure} run-with-state @var{mval} [@var{state}]
+Run monadic value @var{mval} starting with @var{state} as the initial
+state.  Return two values: the resulting value, and the resulting state.
+@end deffn
+
+The main interface to the store monad, provided by the @code{(guix store)}
+module, is as follows.
+
+@defvr {Scheme Variable} %store-monad
+The store monad---an alias for @var{%state-monad}.
+
+Values in the store monad encapsulate accesses to the store.  When its
+effect is needed, a value of the store monad must be ``evaluated'' by
+passing it to the @code{run-with-store} procedure (see below.)
+@end defvr
+
+@deffn {Scheme Procedure} run-with-store @var{store} @var{mval} [#:guile-for-build] [#:system (%current-system)]
+Run @var{mval}, a monadic value in the store monad, in @var{store}, an open
+store connection.
+@end deffn
+
+@deffn {Monadic Procedure} text-file @var{name} @var{text} [@var{references}]
+Return as a monadic value the absolute file name in the store of the file
+containing @var{text}, a string.  @var{references} is a list of store items
+that the resulting text file refers to; it defaults to the empty list.
+@end deffn
+
+@deffn {Monadic Procedure} interned-file @var{file} [@var{name}] @
+         [#:recursive? #t] [#:select? (const #t)] Return the name of @var{file} once
+interned in the store.  Use @var{name} as its store name, or the basename of
+@var{file} if @var{name} is omitted.
+
+When @var{recursive?} is true, the contents of @var{file} are added
+recursively; if @var{file} designates a flat file and @var{recursive?} is
+true, its contents are added, and its permission bits are kept.
+
+When @var{recursive?} is true, call @code{(@var{select?} @var{file}
+@var{stat})} for each directory entry, where @var{file} is the entry's
+absolute file name and @var{stat} is the result of @code{lstat}; exclude
+entries for which @var{select?} does not return true.
+
+The example below adds a file to the store, under two different names:
+
+@example
+(run-with-store (open-connection)
+  (mlet %store-monad ((a (interned-file "README"))
+                      (b (interned-file "README" "LEGU-MIN")))
+    (return (list a b))))

+The @code{(guix packages)} module exports the following package-related

+@deffn {Monadic Procedure} package-file @var{package} [@var{file}] @

+@var{output} directory of @var{package}.  When @var{file} is omitted, return
+the name of the @var{output} directory of @var{package}.  When @var{target}
+is true, use it as a cross-compilation target triplet.

+@cindex G-expression
+@cindex build code quoting
+So we have ``derivations'', which represent a sequence of build actions to
+be performed to produce an item in the store (@pxref{Dérivations}).  These
+build actions are performed when asking the daemon to actually build the
+derivations; they are run by the daemon in a container (@pxref{Invoquer guix-daemon}).
+
+@cindex strata of code
+It should come as no surprise that we like to write these build actions in
+Scheme.  When we do that, we end up with two @dfn{strata} of Scheme
+code@footnote{The term @dfn{stratum} in this context was coined by Manuel
+Serrano et al.@: in the context of their work on Hop.  Oleg Kiselyov, who
+has written insightful
+@url{http://okmij.org/ftp/meta-programming/#meta-scheme, essays and code on
+this topic}, refers to this kind of code generation as @dfn{staging}.}: the
+``host code''---code that defines packages, talks to the daemon, etc.---and
+the ``build code''---code that actually performs build actions, such as
+making directories, invoking @command{make}, etc.
+
+To describe a derivation and its build actions, one typically needs to embed
+build code inside host code.  It boils down to manipulating build code as
+data, and the homoiconicity of Scheme---code has a direct representation as
+data---comes in handy for that.  But we need more than the normal
+@code{quasiquote} mechanism in Scheme to construct build expressions.
+
+The @code{(guix gexp)} module implements @dfn{G-expressions}, a form of
+S-expressions adapted to build expressions.  G-expressions, or @dfn{gexps},
+consist essentially of three syntactic forms: @code{gexp}, @code{ungexp},
+and @code{ungexp-splicing} (or simply: @code{#~}, @code{#$}, and
+@code{#$@@}), which are comparable to @code{quasiquote}, @code{unquote}, and
+@code{unquote-splicing}, respectively (@pxref{Expression Syntax,
+@code{quasiquote},, guile, GNU Guile Reference Manual}).  However, there are
+major differences:
+
+@itemize
+@item
+Gexps are meant to be written to a file and run or manipulated by other
+processes.
+
+@item
+When a high-level object such as a package or derivation is unquoted inside
+a gexp, the result is as if its output file name had been introduced.
+
+@item
+Gexps carry information about the packages or derivations they refer to, and
+these dependencies are automatically added as inputs to the build processes
+that use them.
+@end itemize
+
+@cindex lowering, of high-level objects in gexps
+This mechanism is not limited to package and derivation objects:
+@dfn{compilers} able to ``lower'' other high-level objects to derivations or
+files in the store can be defined, such that these objects can also be
+inserted into gexps.  For example, a useful type of high-level objects that
+can be inserted in a gexp is ``file-like objects'', which make it easy to
+add files to the store and to refer to them in derivations and such (see
+@code{local-file} and @code{plain-file} below.)
+
+To illustrate the idea, here is an example of a gexp:
+
+@example
+(define build-exp
+  #~(begin
+      (mkdir #$output)
+      (chdir #$output)
+      (symlink (string-append #$coreutils "/bin/ls")
+               "list-files")))
+@end example
+
+This gexp can be passed to @code{gexp->derivation}; we obtain a derivation
+that builds a directory containing exactly one symlink to
+@file{/gnu/store/@dots{}-coreutils-8.22/bin/ls}:
+
+@example
+(gexp->derivation "the-thing" build-exp)
+@end example
+
+As one would expect, the @code{"/gnu/store/@dots{}-coreutils-8.22"} string
+is substituted to the reference to the @var{coreutils} package in the actual
+build code, and @var{coreutils} is automatically made an input to the
+derivation.  Likewise, @code{#$output} (equivalent to @code{(ungexp
+output)}) is replaced by a string containing the directory name of the
+output of the derivation.
+
+@cindex cross compilation
+In a cross-compilation context, it is useful to distinguish between
+references to the @emph{native} build of a package---that can run on the
+host---versus references to cross builds of a package.  To that end, the
+@code{#+} plays the same role as @code{#$}, but is a reference to a native
+package build:
+
+@example
+(gexp->derivation "vi"
+   #~(begin
+       (mkdir #$output)
+       (system* (string-append #+coreutils "/bin/ln")
+                "-s"
+                (string-append #$emacs "/bin/emacs")
+                (string-append #$output "/bin/vi")))
+   #:target "mips64el-linux-gnu")
+@end example
+
+@noindent
+In the example above, the native build of @var{coreutils} is used, so that
+@command{ln} can actually run on the host; but then the cross-compiled build
+of @var{emacs} is referenced.
+
+@cindex imported modules, for gexps
+@findex with-imported-modules
+Another gexp feature is @dfn{imported modules}: sometimes you want to be
+able to use certain Guile modules from the ``host environment'' in the gexp,
+so those modules should be imported in the ``build environment''.  The
+@code{with-imported-modules} form allows you to express that:
+
+@example
+(let ((build (with-imported-modules '((guix build utils))
+               #~(begin
+                   (use-modules (guix build utils))
+                   (mkdir-p (string-append #$output "/bin"))))))
+  (gexp->derivation "empty-dir"
+                    #~(begin
+                        #$build
+                        (display "success!\n")
+                        #t)))
+@end example
+
+@noindent
+In this example, the @code{(guix build utils)} module is automatically
+pulled into the isolated build environment of our gexp, such that
+@code{(use-modules (guix build utils))} works as expected.
+
+@cindex module closure
+@findex source-module-closure
+Usually you want the @emph{closure} of the module to be imported---i.e., the
+module itself and all the modules it depends on---rather than just the
+module; failing to do that, attempts to use the module will fail because of
+missing dependent modules.  The @code{source-module-closure} procedure
+computes the closure of a module by looking at its source file headers,
+which comes in handy in this case:
+
+@example
+(use-modules (guix modules))   ;for 'source-module-closure'
+
+(with-imported-modules (source-module-closure
+                         '((guix build utils)
+                           (gnu build vm)))
+  (gexp->derivation "something-with-vms"
+                    #~(begin
+                        (use-modules (guix build utils)
+                                     (gnu build vm))
+                        @dots{})))
+@end example
+
+The syntactic form to construct gexps is summarized below.
+
+@deffn {Scheme Syntax} #~@var{exp}
+@deffnx {Scheme Syntax} (gexp @var{exp})
+Return a G-expression containing @var{exp}.  @var{exp} may contain one or
+more of the following forms:
+
+@table @code
+@item #$@var{obj}
+@itemx (ungexp @var{obj})
+Introduce a reference to @var{obj}.  @var{obj} may have one of the supported
+types, for example a package or a derivation, in which case the
+@code{ungexp} form is replaced by its output file name---e.g.,
+@code{"/gnu/store/@dots{}-coreutils-8.22}.
+
+If @var{obj} is a list, it is traversed and references to supported objects
+are substituted similarly.
+
+If @var{obj} is another gexp, its contents are inserted and its dependencies
+are added to those of the containing gexp.
+
+If @var{obj} is another kind of object, it is inserted as is.
+
+@item #$@var{obj}:@var{output}
+@itemx (ungexp @var{obj} @var{output})
+This is like the form above, but referring explicitly to the @var{output} of
+@var{obj}---this is useful when @var{obj} produces multiple outputs
+(@pxref{Des paquets avec plusieurs résultats}).
+
+@item #+@var{obj}
+@itemx #+@var{obj}:output
+@itemx (ungexp-native @var{obj})
+@itemx (ungexp-native @var{obj} @var{output})
+Same as @code{ungexp}, but produces a reference to the @emph{native} build
+of @var{obj} when used in a cross compilation context.
+
+@item #$output[:@var{output}]
+@itemx (ungexp output [@var{output}])
+Insert a reference to derivation output @var{output}, or to the main output
+when @var{output} is omitted.
+
+This only makes sense for gexps passed to @code{gexp->derivation}.
+
+@item #$@@@var{lst}
+@itemx (ungexp-splicing @var{lst})
+Like the above, but splices the contents of @var{lst} inside the containing
+list.
+
+@item #+@@@var{lst}
+@itemx (ungexp-native-splicing @var{lst})
+Like the above, but refers to native builds of the objects listed in
+@var{lst}.
+
+@end table
+
+G-expressions created by @code{gexp} or @code{#~} are run-time objects of
+the @code{gexp?} type (see below.)
+@end deffn
+
+@deffn {Scheme Syntax} with-imported-modules @var{modules} @var{body}@dots{}
+Mark the gexps defined in @var{body}@dots{} as requiring @var{modules} in
+their execution environment.
+
+Each item in @var{modules} can be the name of a module, such as @code{(guix
+build utils)}, or it can be a module name, followed by an arrow, followed by
+a file-like object:
+
+@example
+`((guix build utils)
+  (guix gcrypt)
+  ((guix config) => ,(scheme-file "config.scm"
+                                  #~(define-module @dots{}))))
+@end example
+
+@noindent
+In the example above, the first two modules are taken from the search path,
+and the last one is created from the given file-like object.
+
+This form has @emph{lexical} scope: it has an effect on the gexps directly
+defined in @var{body}@dots{}, but not on those defined, say, in procedures
+called from @var{body}@dots{}.
+@end deffn
+
+@deffn {Scheme Procedure} gexp? @var{obj}
+Return @code{#t} if @var{obj} is a G-expression.
+@end deffn
+
+G-expressions are meant to be written to disk, either as code building some
+derivation, or as plain files in the store.  The monadic procedures below
+allow you to do that (@pxref{La monad du dépôt}, for more information about
+monads.)
+
+@deffn {Monadic Procedure} gexp->derivation @var{name} @var{exp} @
+       [#:system (%current-system)] [#:target #f] [#:graft? #t] @ [#:hash #f]
+[#:hash-algo #f] @ [#:recursive? #f] [#:env-vars '()] [#:modules '()] @
+[#:module-path @var{%load-path}] @ [#:references-graphs #f]
+[#:allowed-references #f] @ [#:disallowed-references #f] @

+"-builder")] @ [#:deprecation-warnings #f] @ [#:local-build? #f]
+[#:substitutable? #t] [#:guile-for-build #f] Return a derivation @var{name}
+that runs @var{exp} (a gexp) with @var{guile-for-build} (a derivation) on
+@var{system}; @var{exp} is stored in a file called @var{script-name}.  When
+@var{target} is true, it is used as the cross-compilation target triplet for
+packages referred to by @var{exp}.
+
+@var{modules} is deprecated in favor of @code{with-imported-modules}.  Its
+meaning is to make @var{modules} available in the evaluation context of
+@var{exp}; @var{modules} is a list of names of Guile modules searched in
+@var{module-path} to be copied in the store, compiled, and made available in
+the load path during the execution of @var{exp}---e.g., @code{((guix build
+utils) (guix build gnu-build-system))}.
+
+@var{graft?} determines whether packages referred to by @var{exp} should be
+grafted when applicable.
+
+When @var{references-graphs} is true, it must be a list of tuples of one of
+the following forms:
+
+@example
+(@var{file-name} @var{package})
+(@var{file-name} @var{package} @var{output})
+(@var{file-name} @var{derivation})
+(@var{file-name} @var{derivation} @var{output})
+(@var{file-name} @var{store-item})
+@end example
+
+The right-hand-side of each element of @var{references-graphs} is
+automatically made an input of the build process of @var{exp}.  In the build
+environment, each @var{file-name} contains the reference graph of the
+corresponding item, in a simple text format.
+
+@var{allowed-references} must be either @code{#f} or a list of output names
+and packages.  In the latter case, the list denotes store items that the
+result is allowed to refer to.  Any reference to another store item will
+lead to a build error.  Similarly for @var{disallowed-references}, which can
+list items that must not be referenced by the outputs.
+
+@var{deprecation-warnings} determines whether to show deprecation warnings
+while compiling modules.  It can be @code{#f}, @code{#t}, or
+@code{'detailed}.
+
+The other arguments are as for @code{derivation} (@pxref{Dérivations}).
+@end deffn
+
+@cindex file-like objects
+The @code{local-file}, @code{plain-file}, @code{computed-file},
+@code{program-file}, and @code{scheme-file} procedures below return
+@dfn{file-like objects}.  That is, when unquoted in a G-expression, these
+objects lead to a file in the store.  Consider this G-expression:
+
+@example
+#~(system* #$(file-append glibc "/sbin/nscd") "-f"
+           #$(local-file "/tmp/my-nscd.conf"))
+@end example
+
+The effect here is to ``intern'' @file{/tmp/my-nscd.conf} by copying it to
+the store.  Once expanded, for instance @i{via} @code{gexp->derivation}, the
+G-expression refers to that copy under @file{/gnu/store}; thus, modifying or
+removing the file in @file{/tmp} does not have any effect on what the
+G-expression does.  @code{plain-file} can be used similarly; it differs in
+that the file content is directly passed as a string.
+
+@deffn {Scheme Procedure} local-file @var{file} [@var{name}] @
+   [#:recursive? #f] [#:select? (const #t)] Return an object representing local
+file @var{file} to add to the store; this object can be used in a gexp.  If
+@var{file} is a relative file name, it is looked up relative to the source
+file where this form appears.  @var{file} will be added to the store under
+@var{name}--by default the base name of @var{file}.
+
+When @var{recursive?} is true, the contents of @var{file} are added
+recursively; if @var{file} designates a flat file and @var{recursive?} is
+true, its contents are added, and its permission bits are kept.
+
+When @var{recursive?} is true, call @code{(@var{select?} @var{file}
+@var{stat})} for each directory entry, where @var{file} is the entry's
+absolute file name and @var{stat} is the result of @code{lstat}; exclude
+entries for which @var{select?} does not return true.
+
+This is the declarative counterpart of the @code{interned-file} monadic
+procedure (@pxref{La monad du dépôt, @code{interned-file}}).
+@end deffn
+
+@deffn {Scheme Procedure} plain-file @var{name} @var{content}
+Return an object representing a text file called @var{name} with the given
+@var{content} (a string) to be added to the store.
+
+This is the declarative counterpart of @code{text-file}.
+@end deffn
+
+@deffn {Scheme Procedure} computed-file @var{name} @var{gexp} @
+          [#:options '(#:local-build? #t)] Return an object representing the store
+item @var{name}, a file or directory computed by @var{gexp}.  @var{options}
+is a list of additional arguments to pass to @code{gexp->derivation}.
+
+This is the declarative counterpart of @code{gexp->derivation}.
+@end deffn
+
+@deffn {Monadic Procedure} gexp->script @var{name} @var{exp} @
+  [#:guile (default-guile)] [#:module-path %load-path] Return an executable
+script @var{name} that runs @var{exp} using @var{guile}, with @var{exp}'s
+imported modules in its search path.  Look up @var{exp}'s modules in
+@var{module-path}.
+
+The example below builds a script that simply invokes the @command{ls}
+command:
+
+@example
+(use-modules (guix gexp) (gnu packages base))
+
+(gexp->script "list-files"
+              #~(execl #$(file-append coreutils "/bin/ls")
+                       "ls"))
+@end example
+
+When ``running'' it through the store (@pxref{La monad du dépôt,
+@code{run-with-store}}), we obtain a derivation that produces an executable
+file @file{/gnu/store/@dots{}-list-files} along these lines:
+
+@example
+#!/gnu/store/@dots{}-guile-2.0.11/bin/guile -ds
+!#
+(execl "/gnu/store/@dots{}-coreutils-8.22"/bin/ls" "ls")

+          [#:guile #f] [#:module-path %load-path] Return an object representing the
+executable store item @var{name} that runs @var{gexp}.  @var{guile} is the

+are looked up in @var{module-path}.

+            [#:set-load-path? #t] [#:module-path %load-path] @ [#:splice? #f] @ [#:guile
+(default-guile)] Return a derivation that builds a file @var{name}
+containing @var{exp}.  When @var{splice?} is true, @var{exp} is considered
+to be a list of expressions that will be spliced in the resulting file.
+
+When @var{set-load-path?} is true, emit code in the resulting file to set
+@code{%load-path} and @code{%load-compiled-path} to honor @var{exp}'s
+imported modules.  Look up @var{exp}'s modules in @var{module-path}.
+
+The resulting file holds references to all the dependencies of @var{exp} or
+a subset thereof.
+@end deffn
+
+@deffn {Scheme Procedure} scheme-file @var{name} @var{exp} [#:splice? #f]
+Return an object representing the Scheme file @var{name} that contains
+@var{exp}.
+
+This is the declarative counterpart of @code{gexp->file}.
+@end deffn
+
+@deffn {Monadic Procedure} text-file* @var{name} @var{text} @dots{}
+Return as a monadic value a derivation that builds a text file containing
+all of @var{text}.  @var{text} may list, in addition to strings, objects of
+any type that can be used in a gexp: packages, derivations, local file
+objects, etc.  The resulting store file holds references to all these.
+
+This variant should be preferred over @code{text-file} anytime the file to
+create will reference items from the store.  This is typically the case when
+building a configuration file that embeds store file names, like this:
+
+@example
+(define (profile.sh)
+  ;; Return the name of a shell script in the store that
+  ;; initializes the 'PATH' environment variable.
+  (text-file* "profile.sh"
+              "export PATH=" coreutils "/bin:"
+              grep "/bin:" sed "/bin\n"))
+@end example
+
+In this example, the resulting @file{/gnu/store/@dots{}-profile.sh} file
+will reference @var{coreutils}, @var{grep}, and @var{sed}, thereby
+preventing them from being garbage-collected during its lifetime.
+@end deffn
+
+@deffn {Scheme Procedure} mixed-text-file @var{name} @var{text} @dots{}
+Return an object representing store file @var{name} containing @var{text}.
+@var{text} is a sequence of strings and file-like objects, as in:
+
+@example
+(mixed-text-file "profile"
+                 "export PATH=" coreutils "/bin:" grep "/bin")
+@end example
+
+This is the declarative counterpart of @code{text-file*}.
+@end deffn
+
+@deffn {Scheme Procedure} file-union @var{name} @var{files}
+Return a @code{<computed-file>} that builds a directory containing all of
+@var{files}.  Each item in @var{files} must be a two-element list where the
+first element is the file name to use in the new directory, and the second
+element is a gexp denoting the target file.  Here's an example:
+
+@example
+(file-union "etc"
+            `(("hosts" ,(plain-file "hosts"
+                                    "127.0.0.1 localhost"))
+              ("bashrc" ,(plain-file "bashrc"
+                                     "alias ls='ls --color'"))))
+@end example
+
+This yields an @code{etc} directory containing these two files.
+@end deffn
+
+@deffn {Scheme Procedure} directory-union @var{name} @var{things}
+Return a directory that is the union of @var{things}, where @var{things} is
+a list of file-like objects denoting directories.  For example:
+
+@example
+(directory-union "guile+emacs" (list guile emacs))
+@end example
+
+yields a directory that is the union of the @code{guile} and @code{emacs}
+packages.
+@end deffn
+
+@deffn {Scheme Procedure} file-append @var{obj} @var{suffix} @dots{}
+Return a file-like object that expands to the concatenation of @var{obj} and
+@var{suffix}, where @var{obj} is a lowerable object and each @var{suffix} is
+a string.
+
+As an example, consider this gexp:
+
+@example
+(gexp->script "run-uname"
+              #~(system* #$(file-append coreutils
+                                        "/bin/uname")))
+@end example
+
+The same effect could be achieved with:
+
+@example
+(gexp->script "run-uname"
+              #~(system* (string-append #$coreutils
+                                        "/bin/uname")))
+@end example
+
+There is one difference though: in the @code{file-append} case, the
+resulting script contains the absolute file name as a string, whereas in the
+second case, the resulting script contains a @code{(string-append @dots{})}
+expression to construct the file name @emph{at run time}.
+@end deffn
+
+
+Of course, in addition to gexps embedded in ``host'' code, there are also
+modules containing build tools.  To make it clear that they are meant to be
+used in the build stratum, these modules are kept in the @code{(guix build
+@dots{})} name space.
+
+@cindex lowering, of high-level objects in gexps
+Internally, high-level objects are @dfn{lowered}, using their compiler, to
+either derivations or store items.  For instance, lowering a package yields
+a derivation, and lowering a @code{plain-file} yields a store item.  This is
+achieved using the @code{lower-object} monadic procedure.
+
+@deffn {Monadic Procedure} lower-object @var{obj} [@var{system}] @
+           [#:target #f] Return as a value in @var{%store-monad} the derivation or
+store item corresponding to @var{obj} for @var{system}, cross-compiling for
+@var{target} if @var{target} is true.  @var{obj} must be an object that has
+an associated gexp compiler, such as a @code{<package>}.

+@section Invoquer @command{guix build}
+
+@cindex package building
+@cindex @command{guix build}
+The @command{guix build} command builds packages or derivations and their
+dependencies, and prints the resulting store paths.  Note that it does not
+modify the user's profile---this is the job of the @command{guix package}
+command (@pxref{Invoquer guix package}).  Thus, it is mainly useful for
+distribution developers.
+
+The general syntax is:
+
+@example
+guix build @var{options} @var{package-or-derivation}@dots{}
+@end example
+
+As an example, the following command builds the latest versions of Emacs and
+of Guile, displays their build logs, and finally displays the resulting
+directories:
+
+@example
+guix build emacs guile
+@end example
+
+Similarly, the following command builds all the available packages:
+
+@example
+guix build --quiet --keep-going \
+  `guix package -A | cut -f1,2 --output-delimiter=@@`
+@end example
+
+@var{package-or-derivation} may be either the name of a package found in the
+software distribution such as @code{coreutils} or @code{coreutils@@8.20}, or
+a derivation such as @file{/gnu/store/@dots{}-coreutils-8.19.drv}.  In the
+former case, a package with the corresponding name (and optionally version)
+is searched for among the GNU distribution modules (@pxref{Modules de paquets}).
+
+Alternatively, the @code{--expression} option may be used to specify a
+Scheme expression that evaluates to a package; this is useful when
+disambiguating among several same-named packages or package variants is
+needed.
+
+There may be zero or more @var{options}.  The available options are
+described in the subsections below.
+
+@menu

+@end menu
+
+@node Options de construction communes
+@subsection Options de construction communes
+
+A number of options that control the build process are common to
+@command{guix build} and other commands that can spawn builds, such as
+@command{guix package} or @command{guix archive}.  These are the following:
+
+@table @code
+
+@item --load-path=@var{directory}
+@itemx -L @var{directory}
+Add @var{directory} to the front of the package module search path
+(@pxref{Modules de paquets}).
+
+This allows users to define their own packages and make them visible to the
+command-line tools.
+
+@item --keep-failed
+@itemx -K
+Keep the build tree of failed builds.  Thus, if a build fails, its build
+tree is kept under @file{/tmp}, in a directory whose name is shown at the
+end of the build log.  This is useful when debugging build issues.
+@xref{Débogage des échecs de construction}, for tips and tricks on how to debug build
+issues.
+
+@item --keep-going
+@itemx -k
+Keep going when some of the derivations fail to build; return only once all
+the builds have either completed or failed.
+
+The default behavior is to stop as soon as one of the specified derivations
+has failed.
+
+@item --dry-run
+@itemx -n
+Do not build the derivations.
+
+@anchor{fallback-option}
+@item --fallback
+When substituting a pre-built binary fails, fall back to building packages
+locally (@pxref{Échec de substitution}).
+
+@item --substitute-urls=@var{urls}
+@anchor{client-substitute-urls}
+Consider @var{urls} the whitespace-separated list of substitute source URLs,
+overriding the default list of URLs of @command{guix-daemon}
+(@pxref{daemon-substitute-urls,, @command{guix-daemon} URLs}).
+
+Cela signifie que les substituts peuvent être téléchargés depuis @var{urls},
+tant qu'ils sont signés par une clef autorisée par l'administrateur système
+(@pxref{Substituts}).
+
+When @var{urls} is the empty string, substitutes are effectively disabled.
+
+@item --no-substitutes
+Ne pas utiliser de substitut pour les résultats de la
+construction. C'est-à-dire, toujours construire localement plutôt que de
+permettre le téléchargement de binaires pré-construits (@pxref{Substituts}).
+
+@item --no-grafts
+Do not ``graft'' packages.  In practice, this means that package updates
+available as grafts are not applied.  @xref{Mises à jour de sécurité}, for more
+information on grafts.
+
+@item --rounds=@var{n}
+Build each derivation @var{n} times in a row, and raise an error if
+consecutive build results are not bit-for-bit identical.
+
+This is a useful way to detect non-deterministic builds processes.
+Non-deterministic build processes are a problem because they make it
+practically impossible for users to @emph{verify} whether third-party
+binaries are genuine.  @xref{Invoquer guix challenge}, for more.
+
+Note that, currently, the differing build results are not kept around, so
+you will have to manually investigate in case of an error---e.g., by
+stashing one of the build results with @code{guix archive --export}
+(@pxref{Invoquer guix archive}), then rebuilding, and finally comparing the
+two results.
+
+@item --no-build-hook
+Do not attempt to offload builds @i{via} the ``build hook'' of the daemon
+(@pxref{Réglages du délestage du démon}).  That is, always build things locally
+instead of offloading builds to remote machines.
+
+@item --max-silent-time=@var{seconds}
+When the build or substitution process remains silent for more than
+@var{seconds}, terminate it and report a build failure.
+
+By default, the daemon's setting is honored (@pxref{Invoquer guix-daemon,
+@code{--max-silent-time}}).
+
+@item --timeout=@var{seconds}
+Likewise, when the build or substitution process lasts for more than
+@var{seconds}, terminate it and report a build failure.
+
+By default, the daemon's setting is honored (@pxref{Invoquer guix-daemon,
+@code{--timeout}}).
+
+@item --verbosity=@var{level}
+Use the given verbosity level.  @var{level} must be an integer between 0 and
+5; higher means more verbose output.  Setting a level of 4 or more may be
+helpful when debugging setup issues with the build daemon.
+
+@item --cores=@var{n}
+@itemx -c @var{n}
+Allow the use of up to @var{n} CPU cores for the build.  The special value
+@code{0} means to use as many CPU cores as available.
+
+@item --max-jobs=@var{n}
+@itemx -M @var{n}
+Allow at most @var{n} build jobs in parallel.  @xref{Invoquer guix-daemon,
+@code{--max-jobs}}, for details about this option and the equivalent
+@command{guix-daemon} option.
+
+@end table
+
+Behind the scenes, @command{guix build} is essentially an interface to the
+@code{package-derivation} procedure of the @code{(guix packages)} module,
+and to the @code{build-derivations} procedure of the @code{(guix
+derivations)} module.
+
+In addition to options explicitly passed on the command line, @command{guix
+build} and other @command{guix} commands that support building honor the
+@code{GUIX_BUILD_OPTIONS} environment variable.
+
+@defvr {Environment Variable} GUIX_BUILD_OPTIONS
+Users can define this variable to a list of command line options that will
+automatically be used by @command{guix build} and other @command{guix}
+commands that can perform builds, as in the example below:
+
+@example
+$ export GUIX_BUILD_OPTIONS="--no-substitutes -c 2 -L /foo/bar"
+@end example
+
+These options are parsed independently, and the result is appended to the
+parsed command-line options.
+@end defvr
+
+
+@node Options de transformation de paquets
+@subsection Options de transformation de paquets
+
+@cindex package variants
+Another set of command-line options supported by @command{guix build} and
+also @command{guix package} are @dfn{package transformation options}.  These
+are options that make it possible to define @dfn{package variants}---for
+instance, packages built from different source code.  This is a convenient
+way to create customized packages on the fly without having to type in the
+definitions of package variants (@pxref{Définition des paquets}).
+
+@table @code
+
+@item --with-source=@var{source}
+@itemx --with-source=@var{package}=@var{source}
+@itemx --with-source=@var{package}@@@var{version}=@var{source}
+Use @var{source} as the source of @var{package}, and @var{version} as its
+version number.  @var{source} must be a file name or a URL, as for
+@command{guix download} (@pxref{Invoquer guix download}).
+
+When @var{package} is omitted, it is taken to be the package name specified
+on the command line that matches the base of @var{source}---e.g., if
+@var{source} is @code{/src/guile-2.0.10.tar.gz}, the corresponding package
+is @code{guile}.
+
+Likewise, when @var{version} is omitted, the version string is inferred from
+@var{source}; in the previous example, it is @code{2.0.10}.
+
+This option allows users to try out versions of packages other than the one
+provided by the distribution.  The example below downloads
+@file{ed-1.7.tar.gz} from a GNU mirror and uses that as the source for the
+@code{ed} package:
+
+@example
+guix build ed --with-source=mirror://gnu/ed/ed-1.7.tar.gz
+@end example
+
+As a developer, @code{--with-source} makes it easy to test release
+candidates:
+
+@example
+guix build guile --with-source=../guile-2.0.9.219-e1bb7.tar.xz
+@end example
+
+@dots{} or to build from a checkout in a pristine environment:
+
+@example
+$ git clone git://git.sv.gnu.org/guix.git
+$ guix build guix --with-source=guix@@1.0=./guix
+@end example
+
+@item --with-input=@var{package}=@var{replacement}
+Replace dependency on @var{package} by a dependency on @var{replacement}.
+@var{package} must be a package name, and @var{replacement} must be a
+package specification such as @code{guile} or @code{guile@@1.8}.
+
+For instance, the following command builds Guix, but replaces its dependency
+on the current stable version of Guile with a dependency on the legacy
+version of Guile, @code{guile@@2.0}:
+
+@example
+guix build --with-input=guile=guile@@2.0 guix
+@end example
+
+This is a recursive, deep replacement.  So in this example, both @code{guix}
+and its dependency @code{guile-json} (which also depends on @code{guile})
+get rebuilt against @code{guile@@2.0}.
+
+This is implemented using the @code{package-input-rewriting} Scheme
+procedure (@pxref{Définition des paquets, @code{package-input-rewriting}}).
+
+@item --with-graft=@var{package}=@var{replacement}
+This is similar to @code{--with-input} but with an important difference:
+instead of rebuilding the whole dependency chain, @var{replacement} is built
+and then @dfn{grafted} onto the binaries that were initially referring to
+@var{package}.  @xref{Mises à jour de sécurité}, for more information on grafts.
+
+For example, the command below grafts version 3.5.4 of GnuTLS onto Wget and
+all its dependencies, replacing references to the version of GnuTLS they
+currently refer to:
+
+@example
+guix build --with-graft=gnutls=gnutls@@3.5.4 wget
+@end example
+
+This has the advantage of being much faster than rebuilding everything.  But
+there is a caveat: it works if and only if @var{package} and
+@var{replacement} are strictly compatible---for example, if they provide a
+library, the application binary interface (ABI) of those libraries must be
+compatible.  If @var{replacement} is somehow incompatible with
+@var{package}, then the resulting package may be unusable.  Use with care!
+
+@end table
+
+@node Options de construction supplémentaires
+@subsection Options de construction supplémentaires
+
+The command-line options presented below are specific to @command{guix
+build}.
+
+@table @code
+
+@item --quiet
+@itemx -q
+Build quietly, without displaying the build log.  Upon completion, the build
+log is kept in @file{/var} (or similar) and can always be retrieved using
+the @option{--log-file} option.
+
+@item --file=@var{file}
+@itemx -f @var{file}
+
+Build the package or derivation that the code within @var{file} evaluates
+to.
+
+As an example, @var{file} might contain a package definition like this
+(@pxref{Définition des paquets}):
+
+@example
+@verbatiminclude package-hello.scm
+@end example
+
+@item --expression=@var{expr}
+@itemx -e @var{expr}
+Build the package or derivation @var{expr} evaluates to.
+
+For example, @var{expr} may be @code{(@@ (gnu packages guile)  guile-1.8)},
+which unambiguously designates this specific variant of version 1.8 of
+Guile.
+
+Alternatively, @var{expr} may be a G-expression, in which case it is used as
+a build program passed to @code{gexp->derivation} (@pxref{G-Expressions}).
+
+Lastly, @var{expr} may refer to a zero-argument monadic procedure
+(@pxref{La monad du dépôt}).  The procedure must return a derivation as a
+monadic value, which is then passed through @code{run-with-store}.
+
+@item --source
+@itemx -S
+Build the source derivations of the packages, rather than the packages
+themselves.
+
+For instance, @code{guix build -S gcc} returns something like
+@file{/gnu/store/@dots{}-gcc-4.7.2.tar.bz2}, which is the GCC source
+tarball.
+
+The returned source tarball is the result of applying any patches and code
+snippets specified in the package @code{origin} (@pxref{Définition des paquets}).
+
+@item --sources
+Fetch and return the source of @var{package-or-derivation} and all their
+dependencies, recursively.  This is a handy way to obtain a local copy of
+all the source code needed to build @var{packages}, allowing you to
+eventually build them even without network access.  It is an extension of
+the @code{--source} option and can accept one of the following optional
+argument values:
+
+@table @code
+@item package
+This value causes the @code{--sources} option to behave in the same way as
+the @code{--source} option.
+
+@item all
+Build the source derivations of all packages, including any source that
+might be listed as @code{inputs}.  This is the default value.
+
+@example
+$ guix build --sources tzdata
+The following derivations will be built:
+   /gnu/store/@dots{}-tzdata2015b.tar.gz.drv
+   /gnu/store/@dots{}-tzcode2015b.tar.gz.drv
+@end example
+
+@item transitive
+Build the source derivations of all packages, as well of all transitive
+inputs to the packages.  This can be used e.g. to prefetch package source
+for later offline building.
+
+@example
+$ guix build --sources=transitive tzdata
+The following derivations will be built:
+   /gnu/store/@dots{}-tzcode2015b.tar.gz.drv
+   /gnu/store/@dots{}-findutils-4.4.2.tar.xz.drv
+   /gnu/store/@dots{}-grep-2.21.tar.xz.drv
+   /gnu/store/@dots{}-coreutils-8.23.tar.xz.drv
+   /gnu/store/@dots{}-make-4.1.tar.xz.drv
+   /gnu/store/@dots{}-bash-4.3.tar.xz.drv
+@dots{}
+@end example
+
+@end table
+
+@item --system=@var{system}
+@itemx -s @var{system}
+Attempt to build for @var{system}---e.g., @code{i686-linux}---instead of the
+system type of the build host.
+
+@quotation Note
+The @code{--system} flag is for @emph{native} compilation and must not be
+confused with cross-compilation.  See @code{--target} below for information
+on cross-compilation.
+@end quotation
+
+An example use of this is on Linux-based systems, which can emulate
+different personalities.  For instance, passing @code{--system=i686-linux}
+on an @code{x86_64-linux} system allows you to build packages in a complete
+32-bit environment.
+
+Similarly, when transparent emulation with QEMU and @code{binfmt_misc} is
+enabled (@pxref{Virtualization Services, @code{qemu-binfmt-service-type}}),
+you can build for any system for which a QEMU @code{binfmt_misc} handler is
+installed.
+
+Builds for a system other than that of the machine you are using can also be
+offloaded to a remote machine of the right architecture.  @xref{Réglages du délestage du démon}, for more information on offloading.
+
+@item --target=@var{triplet}
+@cindex cross-compilation
+Cross-build for @var{triplet}, which must be a valid GNU triplet, such as
+@code{"mips64el-linux-gnu"} (@pxref{Specifying target triplets, GNU
+configuration triplets,, autoconf, Autoconf}).
+
+@anchor{build-check}
+@item --check
+@cindex déterminisme, vérification
+@cindex reproductibilité, vérification
+Rebuild @var{package-or-derivation}, which are already available in the
+store, and raise an error if the build results are not bit-for-bit

+Make @var{file} a symlink to the result, and register it as a garbage
+collector root.
+
+Consequently, the results of this @command{guix build} invocation are
+protected from garbage collection until @var{file} is removed.  When that
+option is omitted, build results are eligible for garbage collection as soon
+as the build completes.  @xref{Invoquer guix gc}, for more on GC roots.
+
+@item --log-file
+@cindex build logs, access
+Return the build log file names or URLs for the given
+@var{package-or-derivation}, or raise an error if build logs are missing.
+
+This works regardless of how packages or derivations are specified.  For
+instance, the following invocations are equivalent:
+
+@example
+guix build --log-file `guix build -d guile`
+guix build --log-file `guix build guile`
+guix build --log-file guile
+guix build --log-file -e '(@@ (gnu packages guile) guile-2.0)'
+@end example
+
+If a log is unavailable locally, and unless @code{--no-substitutes} is
+passed, the command looks for a corresponding log on one of the substitute
+servers (as specified with @code{--substitute-urls}.)
+
+So for instance, imagine you want to see the build log of GDB on MIPS, but
+you are actually on an @code{x86_64} machine:
+
+@example
+$ guix build --log-file gdb -s mips64el-linux
+https://hydra.gnu.org/log/@dots{}-gdb-7.10
+@end example
+
+You can freely access a huge library of build logs!

+@subsection Débogage des échecs de construction
+
+@cindex build failures, debugging
+When defining a new package (@pxref{Définition des paquets}), you will probably
+find yourself spending some time debugging and tweaking the build until it
+succeeds.  To do that, you need to operate the build commands yourself in an
+environment as close as possible to the one the build daemon uses.
+
+To that end, the first thing to do is to use the @option{--keep-failed} or
+@option{-K} option of @command{guix build}, which will keep the failed build
+tree in @file{/tmp} or whatever directory you specified as @code{TMPDIR}
+(@pxref{Invoquer guix build, @code{--keep-failed}}).
+
+From there on, you can @command{cd} to the failed build tree and source the
+@file{environment-variables} file, which contains all the environment
+variable definitions that were in place when the build failed.  So let's say
+you're debugging a build failure in package @code{foo}; a typical session
+would look like this:
+
+@example
+$ guix build foo -K
+@dots{} @i{build fails}
+$ cd /tmp/guix-build-foo.drv-0
+$ source ./environment-variables
+$ cd foo-1.2
+@end example
+
+Now, you can invoke commands as if you were the daemon (almost) and
+troubleshoot your build process.
+
+Sometimes it happens that, for example, a package's tests pass when you run
+them manually but they fail when the daemon runs them.  This can happen
+because the daemon runs builds in containers where, unlike in our
+environment above, network access is missing, @file{/bin/sh} does not exist,
+etc. (@pxref{Réglages de l'environnement de construction}).
+
+In such cases, you may need to run inspect the build process from within a
+container similar to the one the build daemon creates:
+
+@example
+$ guix build -K foo
+@dots{}
+$ cd /tmp/guix-build-foo.drv-0
+$ guix environment --no-grafts -C foo --ad-hoc strace gdb
+[env]# source ./environment-variables
+[env]# cd foo-1.2
+@end example
+
+Here, @command{guix environment -C} creates a container and spawns a new
+shell in it (@pxref{Invoquer guix environment}).  The @command{--ad-hoc
+strace gdb} part adds the @command{strace} and @command{gdb} commands to the
+container, which would may find handy while debugging.  The
+@option{--no-grafts} option makes sure we get the exact same environment,
+with ungrafted packages (@pxref{Mises à jour de sécurité}, for more info on grafts).
+
+To get closer to a container like that used by the build daemon, we can
+remove @file{/bin/sh}:
+
+@example
+[env]# rm /bin/sh
+@end example
+
+(Don't worry, this is harmless: this is all happening in the throw-away
+container created by @command{guix environment}.)
+
+The @command{strace} command is probably not in the search path, but we can
+run:
+
+@example
+[env]# $GUIX_ENVIRONMENT/bin/strace -f -o log make check
+@end example
+
+In this way, not only you will have reproduced the environment variables the
+daemon uses, you will also be running the build process in a container
+similar to the one the daemon uses.

+@cindex downloading package sources
+When writing a package definition, developers typically need to download a
+source tarball, compute its SHA256 hash, and write that hash in the package
+definition (@pxref{Définition des paquets}).  The @command{guix download} tool
+helps with this task: it downloads a file from the given URI, adds it to the
+store, and prints both its file name in the store and its SHA256 hash.
+
+The fact that the downloaded file is added to the store saves bandwidth:
+when the developer eventually tries to build the newly defined package with
+@command{guix build}, the source tarball will not have to be downloaded
+again because it is already in the store.  It is also a convenient way to
+temporarily stash files, which may be deleted eventually (@pxref{Invoquer guix gc}).
+
+The @command{guix download} command supports the same URIs as used in
+package definitions.  In particular, it supports @code{mirror://} URIs.
+@code{https} URIs (HTTP over TLS) are supported @emph{provided} the Guile
+bindings for GnuTLS are available in the user's environment; when they are
+not available, an error is raised.  @xref{Guile Preparations, how to install
+the GnuTLS bindings for Guile,, gnutls-guile, GnuTLS-Guile}, for more
+information.
+
+@command{guix download} verifies HTTPS server certificates by loading the
+certificates of X.509 authorities from the directory pointed to by the
+@code{SSL_CERT_DIR} environment variable (@pxref{Certificats X.509}),
+unless @option{--no-check-certificate} is used.
+

+on the valid values for @var{fmt}, @pxref{Invoquer guix hash}.
+
+@item --no-check-certificate
+Do not validate the X.509 certificates of HTTPS servers.
+
+When using this option, you have @emph{absolutely no guarantee} that you are

+The @command{guix hash} command computes the SHA256 hash of a file.  It is
+primarily a convenience tool for anyone contributing to the distribution: it
+computes the cryptographic hash of a file, which can be used in the
+definition of a package (@pxref{Définition des paquets}).
+
+The general syntax is:
+
+@example
+guix hash @var{option} @var{file}
+@end example
+
+When @var{file} is @code{-} (a hyphen), @command{guix hash} computes the
+hash of data read from standard input.  @command{guix hash} has the
+following options:
+
+@table @code
+
+@item --format=@var{fmt}
+@itemx -f @var{fmt}
+Write the hash in the format specified by @var{fmt}.
+
+Supported formats: @code{nix-base32}, @code{base32}, @code{base16}
+(@code{hex} and @code{hexadecimal} can be used as well).
+
+If the @option{--format} option is not specified, @command{guix hash} will
+output the hash in @code{nix-base32}.  This representation is used in the
+definitions of packages.
+
+@item --recursive
+@itemx -r
+Compute the hash on @var{file} recursively.
+
+@c FIXME: Replace xref above with xref to an ``Archive'' section when
+@c it exists.
+In this case, the hash is computed on an archive containing @var{file},
+including its children if it is a directory.  Some of the metadata of
+@var{file} is part of the archive; for instance, when @var{file} is a
+regular file, the hash is different depending on whether @var{file} is
+executable or not.  Metadata such as time stamps has no impact on the hash
+(@pxref{Invoquer guix archive}).

+The @command{guix import} command is useful for people who would like to add

+demand.  The command knows of a few repositories from which it can
+``import'' package metadata.  The result is a package definition, or a
+template thereof, in the format we know (@pxref{Définition des paquets}).
+
+The general syntax is:
+
+@example
+guix import @var{importer} @var{options}@dots{}

+
+@var{importer} specifies the source from which to import package metadata,
+and @var{options} specifies a package identifier and other options specific
+to @var{importer}.  Currently, the available ``importers'' are:
+
+@table @code
+@item gnu
+Import metadata for the given GNU package.  This provides a template for the
+latest version of that GNU package, including the hash of its source
+tarball, and its canonical synopsis and description.
+
+Additional information such as the package dependencies and its license
+needs to be figured out manually.
+
+For example, the following command returns a package definition for
+GNU@tie{}Hello:
+
+@example
+guix import gnu hello
+@end example
+
+Specific command-line options are:

+@node Invoquer guix refresh
+@section Invoking @command{guix refresh}
+
+@cindex @command{guix refresh}
+The primary audience of the @command{guix refresh} command is developers of
+the GNU software distribution.  By default, it reports any packages provided
+by the distribution that are outdated compared to the latest upstream
+version, like this:
+
+@example
+$ guix refresh
+gnu/packages/gettext.scm:29:13: gettext would be upgraded from 0.18.1.1 to 0.18.2.1
+gnu/packages/glib.scm:77:12: glib would be upgraded from 2.34.3 to 2.37.0
+@end example
+
+Alternately, one can specify packages to consider, in which case a warning
+is emitted for packages that lack an updater:
+
+@example
+$ guix refresh coreutils guile guile-ssh
+gnu/packages/ssh.scm:205:2: warning: no updater for guile-ssh
+gnu/packages/guile.scm:136:12: guile would be upgraded from 2.0.12 to 2.0.13
+@end example
+
+@command{guix refresh} browses the upstream repository of each package and
+determines the highest version number of the releases therein.  The command
+knows how to update specific types of packages: GNU packages, ELPA packages,
+etc.---see the documentation for @option{--type} below.  There are many
+packages, though, for which it lacks a method to determine whether a new
+upstream release is available.  However, the mechanism is extensible, so
+feel free to get in touch with us to add a new method!
+
+Sometimes the upstream name differs from the package name used in Guix, and
+@command{guix refresh} needs a little help.  Most updaters honor the
+@code{upstream-name} property in package definitions, which can be used to
+that effect:
+
+@example
+(define-public network-manager
+  (package
+    (name "network-manager")
+    ;; @dots{}
+    (properties '((upstream-name . "NetworkManager")))))
+@end example
+
+When passed @code{--update}, it modifies distribution source files to update
+the version numbers and source tarball hashes of those package recipes
+(@pxref{Définition des paquets}).  This is achieved by downloading each package's
+latest source tarball and its associated OpenPGP signature, authenticating
+the downloaded tarball against its signature using @command{gpg}, and
+finally computing its hash.  When the public key used to sign the tarball is
+missing from the user's keyring, an attempt is made to automatically
+retrieve it from a public key server; when this is successful, the key is
+added to the user's keyring; otherwise, @command{guix refresh} reports an
+error.
+
+The following options are supported:
+
+@table @code
+
+@item --expression=@var{expr}
+@itemx -e @var{expr}
+Consider the package @var{expr} evaluates to.
+
+This is useful to precisely refer to a package, as in this example:
+
+@example
+guix refresh -l -e '(@@@@ (gnu packages commencement) glibc-final)'
+@end example
+
+This command lists the dependents of the ``final'' libc (essentially all the
+packages.)
+
+@item --update
+@itemx -u
+Update distribution source files (package recipes) in place.  This is
+usually run from a checkout of the Guix source tree (@pxref{Lancer Guix avant qu'il ne soit installé}):
+
+@example
+$ ./pre-inst-env guix refresh -s non-core -u
+@end example
+
+@xref{Définition des paquets}, for more information on package definitions.
+
+@item --select=[@var{subset}]
+@itemx -s @var{subset}
+Select all the packages in @var{subset}, one of @code{core} or
+@code{non-core}.
+
+The @code{core} subset refers to all the packages at the core of the
+distribution---i.e., packages that are used to build ``everything else''.
+This includes GCC, libc, Binutils, Bash, etc.  Usually, changing one of
+these packages in the distribution entails a rebuild of all the others.
+Thus, such updates are an inconvenience to users in terms of build time or
+bandwidth used to achieve the upgrade.
+
+The @code{non-core} subset refers to the remaining packages.  It is
+typically useful in cases where an update of the core packages would be
+inconvenient.
+
+@item --manifest=@var{file}
+@itemx -m @var{file}
+Select all the packages from the manifest in @var{file}. This is useful to
+check if any packages of the user manifest can be updated.
+
+@item --type=@var{updater}
+@itemx -t @var{updater}
+Select only packages handled by @var{updater} (may be a comma-separated list
+of updaters).  Currently, @var{updater} may be one of:
+
+@table @code
+@item gnu
+the updater for GNU packages;
+@item gnome
+the updater for GNOME packages;
+@item kde
+the updater for KDE packages;
+@item xorg
+the updater for X.org packages;
+@item kernel.org
+the updater for packages hosted on kernel.org;
+@item elpa
+the updater for @uref{http://elpa.gnu.org/, ELPA} packages;
+@item cran
+the updater for @uref{https://cran.r-project.org/, CRAN} packages;
+@item bioconductor
+the updater for @uref{https://www.bioconductor.org/, Bioconductor} R

+@item cpan
+the updater for @uref{http://www.cpan.org/, CPAN} packages;
+@item pypi
+the updater for @uref{https://pypi.python.org, PyPI} packages.
+@item gem
+the updater for @uref{https://rubygems.org, RubyGems} packages.
+@item github
+the updater for @uref{https://github.com, GitHub} packages.
+@item hackage
+the updater for @uref{https://hackage.haskell.org, Hackage} packages.
+@item stackage
+the updater for @uref{https://www.stackage.org, Stackage} packages.
+@item crate
+the updater for @uref{https://crates.io, Crates} packages.
+@end table
+
+For instance, the following command only checks for updates of Emacs
+packages hosted at @code{elpa.gnu.org} and for updates of CRAN packages:
+
+@example
+$ guix refresh --type=elpa,cran
+gnu/packages/statistics.scm:819:13: r-testthat would be upgraded from 0.10.0 to 0.11.0
+gnu/packages/emacs.scm:856:13: emacs-auctex would be upgraded from 11.88.6 to 11.88.9
+@end example
+
+@end table
+
+In addition, @command{guix refresh} can be passed one or more package names,
+as in this example:
+
+@example
+$ ./pre-inst-env guix refresh -u emacs idutils gcc@@4.8
+@end example
+
+@noindent
+The command above specifically updates the @code{emacs} and @code{idutils}
+packages.  The @code{--select} option would have no effect in this case.
+
+When considering whether to upgrade a package, it is sometimes convenient to
+know which packages would be affected by the upgrade and should be checked
+for compatibility.  For this the following option may be used when passing
+@command{guix refresh} one or more package names:
+
+@table @code
+
+@item --list-updaters
+@itemx -L
+List available updaters and exit (see @option{--type} above.)
+
+For each updater, display the fraction of packages it covers; at the end,
+display the fraction of packages covered by all these updaters.
+
+@item --list-dependent
+@itemx -l
+List top-level dependent packages that would need to be rebuilt as a result
+of upgrading one or more packages.
+
+@xref{Invoquer guix graph, the @code{reverse-package} type of @command{guix
+graph}}, for information on how to visualize the list of dependents of a
+package.
+
+@end table
+
+Be aware that the @code{--list-dependent} option only @emph{approximates}
+the rebuilds that would be required as a result of an upgrade.  More
+rebuilds might be required under some circumstances.
+
+@example
+$ guix refresh --list-dependent flex
+Building the following 120 packages would ensure 213 dependent packages are rebuilt:
+hop@@2.4.0 geiser@@0.4 notmuch@@0.18 mu@@0.9.9.5 cflow@@1.4 idutils@@4.6 @dots{}
+@end example
+
+The command above lists a set of packages that could be built to check for
+compatibility with an upgraded @code{flex} package.
+
+The following options can be used to customize GnuPG operation:
+
+@table @code
+
+@item --gpg=@var{command}
+Use @var{command} as the GnuPG 2.x command.  @var{command} is searched for
+in @code{$PATH}.
+
+@item --key-download=@var{policy}
+Handle missing OpenPGP keys according to @var{policy}, which may be one of:
+
+@table @code
+@item always
+Always download missing OpenPGP keys from the key server, and add them to
+the user's GnuPG keyring.
+
+@item never
+Never try to download missing OpenPGP keys.  Instead just bail out.
+
+@item interactive
+When a package signed with an unknown OpenPGP key is encountered, ask the
+user whether to download it or not.  This is the default behavior.
+@end table
+
+@item --key-server=@var{host}
+Use @var{host} as the OpenPGP key server when importing a public key.
+
+@end table
+
+The @code{github} updater uses the @uref{https://developer.github.com/v3/,
+GitHub API} to query for new releases.  When used repeatedly e.g. when
+refreshing all packages, GitHub will eventually refuse to answer any further
+API requests.  By default 60 API requests per hour are allowed, and a full
+refresh on all GitHub packages in Guix requires more than this.
+Authentication with GitHub through the use of an API token alleviates these
+limits.  To use an API token, set the environment variable
+@code{GUIX_GITHUB_TOKEN} to a token procured from
+@uref{https://github.com/settings/tokens} or otherwise.

+@node Invoquer guix size
+@section Invoking @command{guix size}
+
+@cindex size
+@cindex package size
+@cindex closure
+@cindex @command{guix size}
+The @command{guix size} command helps package developers profile the disk
+usage of packages.  It is easy to overlook the impact of an additional
+dependency added to a package, or the impact of using a single output for a
+package that could easily be split (@pxref{Des paquets avec plusieurs résultats}).  Such are the typical issues that @command{guix size} can
+highlight.
+
+The command can be passed a package specification such as @code{gcc@@4.8} or
+@code{guile:debug}, or a file name in the store.  Consider this example:
+
+@example
+$ guix size coreutils
+store item                               total    self
+/gnu/store/@dots{}-coreutils-8.23          70.0    13.9  19.8%
+/gnu/store/@dots{}-gmp-6.0.0a              55.3     2.5   3.6%
+/gnu/store/@dots{}-acl-2.2.52              53.7     0.5   0.7%
+/gnu/store/@dots{}-attr-2.4.46             53.2     0.3   0.5%
+/gnu/store/@dots{}-gcc-4.8.4-lib           52.9    15.7  22.4%
+/gnu/store/@dots{}-glibc-2.21              37.2    37.2  53.1%
+@end example
+
+@cindex closure
+The store items listed here constitute the @dfn{transitive closure} of
+Coreutils---i.e., Coreutils and all its dependencies, recursively---as would
+be returned by:
+
+@example
+$ guix gc -R /gnu/store/@dots{}-coreutils-8.23
+@end example
+
+Here the output shows three columns next to store items.  The first column,
+labeled ``total'', shows the size in mebibytes (MiB) of the closure of the
+store item---that is, its own size plus the size of all its dependencies.
+The next column, labeled ``self'', shows the size of the item itself.  The
+last column shows the ratio of the size of the item itself to the space
+occupied by all the items listed here.
+
+In this example, we see that the closure of Coreutils weighs in at
+70@tie{}MiB, half of which is taken by libc.  (That libc represents a large
+fraction of the closure is not a problem @i{per se} because it is always
+available on the system anyway.)
+
+When the package passed to @command{guix size} is available in the store,
+@command{guix size} queries the daemon to determine its dependencies, and
+measures its size in the store, similar to @command{du -ms --apparent-size}
+(@pxref{du invocation,,, coreutils, GNU Coreutils}).
+
+Lorsque le paquet donné n'est @emph{pas} dans le dépôt, @command{guix size}
+rapporte les informations en se basant sur les substituts disponibles
+(@pxref{Substituts}). Cela permet de profiler l'utilisation du disque des
+éléments du dépôt qui ne sont pas sur le disque, mais seulement disponibles
+à distance.
+
+You can also specify several package names:
+
+@example
+$ guix size coreutils grep sed bash
+store item                               total    self
+/gnu/store/@dots{}-coreutils-8.24          77.8    13.8  13.4%
+/gnu/store/@dots{}-grep-2.22               73.1     0.8   0.8%
+/gnu/store/@dots{}-bash-4.3.42             72.3     4.7   4.6%
+/gnu/store/@dots{}-readline-6.3            67.6     1.2   1.2%
+@dots{}
+total: 102.3 MiB
+@end example
+
+@noindent
+In this example we see that the combination of the four packages takes
+102.3@tie{}MiB in total, which is much less than the sum of each closure
+since they have a lot of dependencies in common.
+
+The available options are:
+
+@table @option
+
+@item --substitute-urls=@var{urls}
+Use substitute information from @var{urls}.  @xref{client-substitute-urls,
+the same option for @code{guix build}}.
+
+@item --sort=@var{key}
+Sort lines according to @var{key}, one of the following options:
+
+@table @code
+@item self
+the size of each item (the default);
+@item closure
+the total size of the item's closure.
+@end table
+
+@item --map-file=@var{file}
+Write a graphical map of disk usage in PNG format to @var{file}.
+
+For the example above, the map looks like this:
+
+@image{images/coreutils-size-map,5in,, map of Coreutils disk usage produced
+by @command{guix size}}
+
+This option requires that
+@uref{http://wingolog.org/software/guile-charting/, Guile-Charting} be
+installed and visible in Guile's module search path.  When that is not the
+case, @command{guix size} fails as it tries to load it.
+
+@item --system=@var{system}
+@itemx -s @var{system}
+Consider packages for @var{system}---e.g., @code{x86_64-linux}.

+
+@cindex DAG
+@cindex @command{guix graph}
+@cindex package dependencies
+Packages and their dependencies form a @dfn{graph}, specifically a directed
+acyclic graph (DAG).  It can quickly become difficult to have a mental model
+of the package DAG, so the @command{guix graph} command provides a visual
+representation of the DAG.  By default, @command{guix graph} emits a DAG
+representation in the input format of @uref{http://www.graphviz.org/,
+Graphviz}, so its output can be passed directly to the @command{dot} command
+of Graphviz.  It can also emit an HTML page with embedded JavaScript code to
+display a ``chord diagram'' in a Web browser, using the
+@uref{https://d3js.org/, d3.js} library, or emit Cypher queries to construct
+a graph in a graph database supporting the @uref{http://www.opencypher.org/,
+openCypher} query language.  The general syntax is:
+
+@example
+guix graph @var{options} @var{package}@dots{}
+@end example
+
+For example, the following command generates a PDF file representing the
+package DAG for the GNU@tie{}Core Utilities, showing its build-time
+dependencies:
+
+@example
+guix graph coreutils | dot -Tpdf > dag.pdf
+@end example
+
+The output looks like this:
+
+@image{images/coreutils-graph,2in,,Dependency graph of the GNU Coreutils}
+
+Nice little graph, no?
+
+But there is more than one graph! The one above is concise: it is the graph
+of package objects, omitting implicit inputs such as GCC, libc, grep, etc.
+It is often useful to have such a concise graph, but sometimes one may want
+to see more details.  @command{guix graph} supports several types of graphs,
+allowing you to choose the level of detail:
+
+@table @code
+@item package
+This is the default type used in the example above.  It shows the DAG of
+package objects, excluding implicit dependencies.  It is concise, but
+filters out many details.
+
+@item reverse-package
+This shows the @emph{reverse} DAG of packages.  For example:
+
+@example
+guix graph --type=reverse-package ocaml
+@end example
+
+... yields the graph of packages that depend on OCaml.
+
+Note that for core packages this can yield huge graphs.  If all you want is
+to know the number of packages that depend on a given package, use
+@command{guix refresh --list-dependent} (@pxref{Invoquer guix refresh,
+@option{--list-dependent}}).
+
+@item bag-emerged
+This is the package DAG, @emph{including} implicit inputs.
+
+For instance, the following command:
+
+@example
+guix graph --type=bag-emerged coreutils | dot -Tpdf > dag.pdf
+@end example
+
+... yields this bigger graph:
+
+@image{images/coreutils-bag-graph,,5in,Detailed dependency graph of the GNU
+Coreutils}
+
+At the bottom of the graph, we see all the implicit inputs of
+@var{gnu-build-system} (@pxref{Systèmes de construction, @code{gnu-build-system}}).
+
+Now, note that the dependencies of these implicit inputs---that is, the
+@dfn{bootstrap dependencies} (@pxref{Bootstrapping})---are not shown here,
+for conciseness.
+
+@item bag
+Similar to @code{bag-emerged}, but this time including all the bootstrap
+dependencies.
+
+@item bag-with-origins
+Similar to @code{bag}, but also showing origins and their dependencies.
+
+@item derivation
+This is the most detailed representation: It shows the DAG of derivations
+(@pxref{Dérivations}) and plain store items.  Compared to the above
+representation, many additional nodes are visible, including build scripts,
+patches, Guile modules, etc.
+
+For this type of graph, it is also possible to pass a @file{.drv} file name
+instead of a package name, as in:
+
+@example
+guix graph -t derivation `guix system build -d my-config.scm`
+@end example
+
+@item module
+This is the graph of @dfn{package modules} (@pxref{Modules de paquets}).  For
+example, the following command shows the graph for the package module that
+defines the @code{guile} package:
+
+@example
+guix graph -t module guile | dot -Tpdf > module-graph.pdf
+@end example
+@end table
+
+All the types above correspond to @emph{build-time dependencies}.  The
+following graph type represents the @emph{run-time dependencies}:
+
+@table @code
+@item references
+This is the graph of @dfn{references} of a package output, as returned by
+@command{guix gc --references} (@pxref{Invoquer guix gc}).
+
+If the given package output is not available in the store, @command{guix
+graph} attempts to obtain dependency information from substitutes.
+
+Here you can also pass a store file name instead of a package name.  For
+example, the command below produces the reference graph of your profile
+(which can be big!):
+
+@example
+guix graph -t references `readlink -f ~/.guix-profile`
+@end example
+
+@item referrers
+This is the graph of the @dfn{referrers} of a store item, as returned by
+@command{guix gc --referrers} (@pxref{Invoquer guix gc}).
+
+This relies exclusively on local information from your store.  For instance,
+let us suppose that the current Inkscape is available in 10 profiles on your
+machine; @command{guix graph -t referrers inkscape} will show a graph rooted
+at Inkscape and with those 10 profiles linked to it.
+
+It can help determine what is preventing a store item from being garbage
+collected.
+
+@end table
+
+The available options are the following:
+
+@table @option

+@cindex reproducible build environments
+@cindex development environments
+@cindex @command{guix environment}
+@cindex environment, package build environment
+The purpose of @command{guix environment} is to assist hackers in creating
+reproducible development environments without polluting their package
+profile.  The @command{guix environment} tool takes one or more packages,
+builds all of their inputs, and creates a shell environment to use them.
+
+The general syntax is:
+
+@example
+guix environment @var{options} @var{package}@dots{}
+@end example
+
+The following example spawns a new shell set up for the development of
+GNU@tie{}Guile:
+
+@example
+guix environment guile
+@end example
+
+If the needed dependencies are not built yet, @command{guix environment}
+automatically builds them.  The environment of the new shell is an augmented
+version of the environment that @command{guix environment} was run in.  It
+contains the necessary search paths for building the given package added to
+the existing environment variables.  To create a ``pure'' environment, in
+which the original environment variables have been unset, use the
+@code{--pure} option@footnote{Users sometimes wrongfully augment environment
+variables such as @code{PATH} in their @file{~/.bashrc} file.  As a
+consequence, when @code{guix environment} launches it, Bash may read
+@file{~/.bashrc}, thereby introducing ``impurities'' in these environment
+variables.  It is an error to define such environment variables in
+@file{.bashrc}; instead, they should be defined in @file{.bash_profile},
+which is sourced only by log-in shells.  @xref{Bash Startup Files,,, bash,
+The GNU Bash Reference Manual}, for details on Bash start-up files.}.
+
+@vindex GUIX_ENVIRONMENT
+@command{guix environment} defines the @code{GUIX_ENVIRONMENT} variable in
+the shell it spawns; its value is the file name of the profile of this
+environment.  This allows users to, say, define a specific prompt for
+development environments in their @file{.bashrc} (@pxref{Bash Startup
+Files,,, bash, The GNU Bash Reference Manual}):
+
+@example
+if [ -n "$GUIX_ENVIRONMENT" ]
+then
+    export PS1="\u@@\h \w [dev]\$ "
+fi
+@end example
+
+@noindent
+... or to browse the profile:
+
+@example
+$ ls "$GUIX_ENVIRONMENT/bin"
+@end example
+
+Additionally, more than one package may be specified, in which case the
+union of the inputs for the given packages are used.  For example, the
+command below spawns a shell where all of the dependencies of both Guile and
+Emacs are available:
+
+@example
+guix environment guile emacs
+@end example
+
+Sometimes an interactive shell session is not desired.  An arbitrary command
+may be invoked by placing the @code{--} token to separate the command from
+the rest of the arguments:
+
+@example
+guix environment guile -- make -j4
+@end example
+
+In other situations, it is more convenient to specify the list of packages
+needed in the environment.  For example, the following command runs
+@command{python} from an environment containing Python@tie{}2.7 and NumPy:
+
+@example
+guix environment --ad-hoc python2-numpy python-2.7 -- python
+@end example
+
+Furthermore, one might want the dependencies of a package and also some
+additional packages that are not build-time or runtime dependencies, but are
+useful when developing nonetheless.  Because of this, the @code{--ad-hoc}
+flag is positional.  Packages appearing before @code{--ad-hoc} are
+interpreted as packages whose dependencies will be added to the
+environment.  Packages appearing after are interpreted as packages that will
+be added to the environment directly.  For example, the following command
+creates a Guix development environment that additionally includes Git and
+strace:
+
+@example
+guix environment guix --ad-hoc git strace
+@end example
+
+Sometimes it is desirable to isolate the environment as much as possible,
+for maximal purity and reproducibility.  In particular, when using Guix on a
+host distro that is not GuixSD, it is desirable to prevent access to
+@file{/usr/bin} and other system-wide resources from the development
+environment.  For example, the following command spawns a Guile REPL in a
+``container'' where only the store and the current working directory are
+mounted:
+
+@example
+guix environment --ad-hoc --container guile -- guile
+@end example
+
+@quotation Note
+The @code{--container} option requires Linux-libre 3.19 or newer.
+@end quotation
+
+The available options are summarized below.
+
+@table @code
+@item --root=@var{file}
+@itemx -r @var{file}
+@cindex persistent environment
+@cindex garbage collector root, for environments
+Make @var{file} a symlink to the profile for this environment, and register
+it as a garbage collector root.
+
+This is useful if you want to protect your environment from garbage
+collection, to make it ``persistent''.
+
+When this option is omitted, the environment is protected from garbage
+collection only for the duration of the @command{guix environment} session.
+This means that next time you recreate the same environment, you could have
+to rebuild or re-download packages.  @xref{Invoquer guix gc}, for more on GC
+roots.
+
+@item --expression=@var{expr}
+@itemx -e @var{expr}
+Create an environment for the package or list of packages that @var{expr}
+evaluates to.
+
+For example, running:
+
+@example
+guix environment -e '(@@ (gnu packages maths) petsc-openmpi)'
+@end example
+
+starts a shell with the environment for this specific variant of the PETSc
+package.
+
+Running:
+
+@example
+guix environment --ad-hoc -e '(@@ (gnu) %base-packages)'
+@end example
+
+starts a shell with all the GuixSD base packages available.
+
+The above commands only use the default output of the given packages.  To
+select other outputs, two element tuples can be specified:
+
+@example
+guix environment --ad-hoc -e '(list (@@ (gnu packages bash) bash) "include")'
+@end example
+
+@item --load=@var{file}
+@itemx -l @var{file}
+Create an environment for the package or list of packages that the code
+within @var{file} evaluates to.
+
+As an example, @var{file} might contain a definition like this
+(@pxref{Définition des paquets}):
+
+@example
+@verbatiminclude environment-gdb.scm
+@end example
+
+@item --manifest=@var{file}
+@itemx -m @var{file}
+Create an environment for the packages contained in the manifest object
+returned by the Scheme code in @var{file}.
+
+This is similar to the same-named option in @command{guix package}
+(@pxref{profile-manifest, @option{--manifest}}) and uses the same manifest
+files.
+
+@item --ad-hoc
+Include all specified packages in the resulting environment, as if an @i{ad
+hoc} package were defined with them as inputs.  This option is useful for
+quickly creating an environment without having to write a package expression
+to contain the desired inputs.
+
+For instance, the command:
+
+@example
+guix environment --ad-hoc guile guile-sdl -- guile
+@end example
+
+runs @command{guile} in an environment where Guile and Guile-SDL are
+available.
+
+Note that this example implicitly asks for the default output of
+@code{guile} and @code{guile-sdl}, but it is possible to ask for a specific
+output---e.g., @code{glib:bin} asks for the @code{bin} output of @code{glib}
+(@pxref{Des paquets avec plusieurs résultats}).
+
+This option may be composed with the default behavior of @command{guix
+environment}.  Packages appearing before @code{--ad-hoc} are interpreted as
+packages whose dependencies will be added to the environment, the default
+behavior.  Packages appearing after are interpreted as packages that will be
+added to the environment directly.
+
+@item --pure
+Unset existing environment variables when building the new environment.
+This has the effect of creating an environment in which search paths only
+contain package inputs.
+
+@item --search-paths
+Display the environment variable definitions that make up the environment.
+
+@item --system=@var{system}
+@itemx -s @var{system}
+Attempt to build for @var{system}---e.g., @code{i686-linux}.
+
+@item --container
+@itemx -C
+@cindex container
+Run @var{command} within an isolated container.  The current working
+directory outside the container is mapped inside the container.
+Additionally, unless overridden with @code{--user}, a dummy home directory
+is created that matches the current user's home directory, and
+@file{/etc/passwd} is configured accordingly.  The spawned process runs as
+the current user outside the container, but has root privileges in the
+context of the container.
+
+@item --network
+@itemx -N
+For containers, share the network namespace with the host system.
+Containers created without this flag only have access to the loopback
+device.
+
+@item --link-profile
+@itemx -P
+For containers, link the environment profile to @file{~/.guix-profile}
+within the container.  This is equivalent to running the command @command{ln
+-s $GUIX_ENVIRONMENT ~/.guix-profile} within the container.  Linking will
+fail and abort the environment if the directory already exists, which will
+certainly be the case if @command{guix environment} was invoked in the
+user's home directory.
+
+Certain packages are configured to look in @code{~/.guix-profile} for
+configuration files and data;@footnote{For example, the @code{fontconfig}
+package inspects @file{~/.guix-profile/share/fonts} for additional fonts.}
+@code{--link-profile} allows these programs to behave as expected within the
+environment.
+
+@item --user=@var{user}
+@itemx -u @var{user}
+For containers, use the username @var{user} in place of the current user.
+The generated @file{/etc/passwd} entry within the container will contain the
+name @var{user}; the home directory will be @file{/home/USER}; and no user
+GECOS data will be copied.  @var{user} need not exist on the system.
+
+Additionally, any shared or exposed path (see @code{--share} and
+@code{--expose} respectively) whose target is within the current user's home
+directory will be remapped relative to @file{/home/USER}; this includes the
+automatic mapping of the current working directory.
+
+@example
+# will expose paths as /home/foo/wd, /home/foo/test, and /home/foo/target
+cd $HOME/wd
+guix environment --container --user=foo \
+     --expose=$HOME/test \
+     --expose=/tmp/target=$HOME/target
+@end example
+
+While this will limit the leaking of user identity through home paths and
+each of the user fields, this is only one useful component of a broader
+privacy/anonymity solution---not one in and of itself.
+
+@item --expose=@var{source}[=@var{target}]
+For containers, expose the file system @var{source} from the host system as
+the read-only file system @var{target} within the container.  If
+@var{target} is not specified, @var{source} is used as the target mount
+point in the container.
+
+The example below spawns a Guile REPL in a container in which the user's
+home directory is accessible read-only via the @file{/exchange} directory:
+
+@example
+guix environment --container --expose=$HOME=/exchange --ad-hoc guile -- guile
+@end example
+
+@item --share=@var{source}[=@var{target}]
+For containers, share the file system @var{source} from the host system as
+the writable file system @var{target} within the container.  If @var{target}
+is not specified, @var{source} is used as the target mount point in the
+container.
+
+The example below spawns a Guile REPL in a container in which the user's
+home directory is accessible for both reading and writing via the
+@file{/exchange} directory:
+
+@example
+guix environment --container --share=$HOME=/exchange --ad-hoc guile -- guile
+@end example
+@end table
+
+@command{guix environment} also supports all of the common build options
+that @command{guix build} supports (@pxref{Options de construction communes}).

+
+@node Invoquer guix publish
+@section Invoking @command{guix publish}
+
+@cindex @command{guix publish}
+Le but de @command{guix publish} est de vous permettre de partager
+facilement votre dépôt avec d'autres personnes qui peuvent ensuite
+l'utiliser comme serveur de substituts (@pxref{Substituts}).
+
+When @command{guix publish} runs, it spawns an HTTP server which allows
+anyone with network access to obtain substitutes from it.  This means that
+any machine running Guix can also act as if it were a build farm, since the
+HTTP interface is compatible with Hydra, the software behind the
+@code{hydra.gnu.org} build farm.
+
+Pour des raisons de sécurité, chaque substitut est signé, ce qui permet aux
+destinataires de vérifier leur authenticité et leur intégrité
+(@pxref{Substituts}). Comme @command{guix publish} utilise la clef de
+signature du système, qui n'est lisible que par l'administrateur système, il
+doit être lancé en root ; l'option @code{--user} lui fait baisser ses
+privilèges le plus tôt possible.
+
+The signing key pair must be generated before @command{guix publish} is
+launched, using @command{guix archive --generate-key} (@pxref{Invoquer guix archive}).
+
+The general syntax is:
+
+@example
+guix publish @var{options}@dots{}
+@end example
+
+Running @command{guix publish} without any additional arguments will spawn
+an HTTP server on port 8080:
+
+@example
+guix publish
+@end example
+
+Once a publishing server has been authorized (@pxref{Invoquer guix archive}), the daemon may download substitutes from it:
+
+@example
+guix-daemon --substitute-urls=http://example.org:8080
+@end example
+
+By default, @command{guix publish} compresses archives on the fly as it
+serves them.  This ``on-the-fly'' mode is convenient in that it requires no
+setup and is immediately available.  However, when serving lots of clients,
+we recommend using the @option{--cache} option, which enables caching of the
+archives before they are sent to clients---see below for details.  The
+@command{guix weather} command provides a handy way to check what a server
+provides (@pxref{Invoquer guix weather}).
+
+As a bonus, @command{guix publish} also serves as a content-addressed mirror
+for source files referenced in @code{origin} records (@pxref{Référence d'origine}).  For instance, assuming @command{guix publish} is running on
+@code{example.org}, the following URL returns the raw
+@file{hello-2.10.tar.gz} file with the given SHA256 hash (represented in
+@code{nix-base32} format, @pxref{Invoquer guix hash}):
+
+@example
+http://example.org/file/hello-2.10.tar.gz/sha256/0ssi1@dots{}ndq1i
+@end example
+
+Obviously, these URLs only work for files that are in the store; in other
+cases, they return 404 (``Not Found'').
+
+@cindex build logs, publication
+Build logs are available from @code{/log} URLs like:
+
+@example
+http://example.org/log/gwspk@dots{}-guile-2.2.3
+@end example
+
+@noindent
+When @command{guix-daemon} is configured to save compressed build logs, as
+is the case by default (@pxref{Invoquer guix-daemon}), @code{/log} URLs
+return the compressed log as-is, with an appropriate @code{Content-Type}
+and/or @code{Content-Encoding} header.  We recommend running
+@command{guix-daemon} with @code{--log-compression=gzip} since Web browsers
+can automatically decompress it, which is not the case with bzip2
+compression.
+
+The following options are available:
+
+@table @code
+@item --port=@var{port}
+@itemx -p @var{port}
+Listen for HTTP requests on @var{port}.
+
+@item --listen=@var{host}
+Listen on the network interface for @var{host}.  The default is to accept
+connections from any interface.
+
+@item --user=@var{user}
+@itemx -u @var{user}
+Change privileges to @var{user} as soon as possible---i.e., once the server
+socket is open and the signing key has been read.
+
+@item --compression[=@var{level}]
+@itemx -C [@var{level}]
+Compress data using the given @var{level}.  When @var{level} is zero,
+disable compression.  The range 1 to 9 corresponds to different gzip
+compression levels: 1 is the fastest, and 9 is the best (CPU-intensive).
+The default is 3.
+
+Unless @option{--cache} is used, compression occurs on the fly and the
+compressed streams are not cached.  Thus, to reduce load on the machine that
+runs @command{guix publish}, it may be a good idea to choose a low
+compression level, to run @command{guix publish} behind a caching proxy, or
+to use @option{--cache}.  Using @option{--cache} has the advantage that it
+allows @command{guix publish} to add @code{Content-Length} HTTP header to
+its responses.
+
+@item --cache=@var{directory}
+@itemx -c @var{directory}
+Cache archives and meta-data (@code{.narinfo} URLs) to @var{directory} and
+only serve archives that are in cache.
+
+When this option is omitted, archives and meta-data are created on-the-fly.
+This can reduce the available bandwidth, especially when compression is
+enabled, since this may become CPU-bound.  Another drawback of the default
+mode is that the length of archives is not known in advance, so
+@command{guix publish} does not add a @code{Content-Length} HTTP header to
+its responses, which in turn prevents clients from knowing the amount of
+data being downloaded.
+
+Conversely, when @option{--cache} is used, the first request for a store
+item (@i{via} a @code{.narinfo} URL) returns 404 and triggers a background
+process to @dfn{bake} the archive---computing its @code{.narinfo} and
+compressing the archive, if needed.  Once the archive is cached in
+@var{directory}, subsequent requests succeed and are served directly from
+the cache, which guarantees that clients get the best possible bandwidth.
+
+The ``baking'' process is performed by worker threads.  By default, one
+thread per CPU core is created, but this can be customized.  See
+@option{--workers} below.
+
+When @option{--ttl} is used, cached entries are automatically deleted when
+they have expired.
+
+@item --workers=@var{N}
+When @option{--cache} is used, request the allocation of @var{N} worker
+threads to ``bake'' archives.
+
+@item --ttl=@var{ttl}
+Produce @code{Cache-Control} HTTP headers that advertise a time-to-live
+(TTL) of @var{ttl}.  @var{ttl} must denote a duration: @code{5d} means 5
+days, @code{1m} means 1 month, and so on.
+
+This allows the user's Guix to keep substitute information in cache for
+@var{ttl}.  However, note that @code{guix publish} does not itself guarantee
+that the store items it provides will indeed remain available for as long as
+@var{ttl}.
+
+Additionally, when @option{--cache} is used, cached entries that have not
+been accessed for @var{ttl} and that no longer have a corresponding item in
+the store, may be deleted.
+
+@item --nar-path=@var{path}
+Use @var{path} as the prefix for the URLs of ``nar'' files (@pxref{Invoquer guix archive, normalized archives}).
+
+By default, nars are served at a URL such as
+@code{/nar/gzip/@dots{}-coreutils-8.25}.  This option allows you to change
+the @code{/nar} part to @var{path}.
+
+@item --public-key=@var{file}
+@itemx --private-key=@var{file}
+Use the specific @var{file}s as the public/private key pair used to sign the
+store items being published.
+
+The files must correspond to the same key pair (the private key is used for
+signing and the public key is merely advertised in the signature metadata).
+They must contain keys in the canonical s-expression format as produced by
+@command{guix archive --generate-key} (@pxref{Invoquer guix archive}).  By
+default, @file{/etc/guix/signing-key.pub} and
+@file{/etc/guix/signing-key.sec} are used.
+
+@item --repl[=@var{port}]
+@itemx -r [@var{port}]
+Spawn a Guile REPL server (@pxref{REPL Servers,,, guile, GNU Guile Reference
+Manual}) on @var{port} (37146 by default).  This is used primarily for
+debugging a running @command{guix publish} server.
+@end table
+
+Enabling @command{guix publish} on a GuixSD system is a one-liner: just
+instantiate a @code{guix-publish-service-type} service in the
+@code{services} field of the @code{operating-system} declaration
+(@pxref{guix-publish-service-type, @code{guix-publish-service-type}}).
+
+If you are instead running Guix on a ``foreign distro'', follow these
+instructions:”
+
+@itemize

+@cindex challenge
+Do the binaries provided by this server really correspond to the source code

+questions the @command{guix challenge} command attempts to answer.
+
+La première question est évidemment importante : avant d'utiliser un serveur
+de substituts (@pxref{Substituts}), il vaut mieux @emph{vérifier} qu'il
+fournit les bons binaires et donc le @emph{défier}. La deuxième est ce qui
+permet la première : si les constructions des paquets sont déterministes
+alors des constructions indépendantes du paquet devraient donner le même
+résultat, bit à bit ; si un serveur fournit un binaire différent de celui
+obtenu localement, il peut être soit corrompu, soit malveillant.
+
+We know that the hash that shows up in @file{/gnu/store} file names is the
+hash of all the inputs of the process that built the file or
+directory---compilers, libraries, build scripts,
+etc. (@pxref{Introduction}).  Assuming deterministic build processes, one
+store file name should map to exactly one build output.  @command{guix
+challenge} checks whether there is, indeed, a single mapping by comparing
+the build outputs of several independent builds of any given store item.
+
+The command output looks like this:

+@end smallexample
+
+@noindent
+In this example, @command{guix challenge} first scans the store to determine
+the set of locally-built derivations---as opposed to store items that were
+downloaded from a substitute server---and then queries all the substitute
+servers.  It then reports those store items for which the servers obtained a
+result different from the local build.
+
+@cindex non-determinism, in package builds
+As an example, @code{guix.example.org} always gets a different answer.
+Conversely, @code{hydra.gnu.org} agrees with local builds, except in the
+case of Git.  This might indicate that the build process of Git is
+non-deterministic, meaning that its output varies as a function of various
+things that Guix does not fully control, in spite of building packages in
+isolated environments (@pxref{Fonctionnalités}).  Most common sources of
+non-determinism include the addition of timestamps in build results, the
+inclusion of random numbers, and directory listings sorted by inode number.
+See @uref{https://reproducible-builds.org/docs/}, for more information.
+
+To find out what is wrong with this Git binary, we can do something along
+these lines (@pxref{Invoquer guix archive}):
+
+@example
+$ wget -q -O - https://hydra.gnu.org/nar/@dots{}-git-2.5.0 \
+   | guix archive -x /tmp/git
+$ diff -ur --no-dereference /gnu/store/@dots{}-git.2.5.0 /tmp/git
+@end example
+
+This command shows the difference between the files resulting from the local
+build, and the files resulting from the build on @code{hydra.gnu.org}
+(@pxref{Overview, Comparing and Merging Files,, diffutils, Comparing and
+Merging Files}).  The @command{diff} command works great for text files.
+When binary files differ, a better option is @uref{https://diffoscope.org/,
+Diffoscope}, a tool that helps visualize differences for all kinds of files.
+
+Once you have done that work, you can tell whether the differences are due
+to a non-deterministic build process or to a malicious server.  We try hard
+to remove sources of non-determinism in packages to make it easier to verify
+substitutes, but of course, this is a process that involves not just Guix,
+but a large part of the free software community.  In the meantime,
+@command{guix challenge} is one tool to help address the problem.
+
+If you are writing packages for Guix, you are encouraged to check whether
+@code{hydra.gnu.org} and other substitute servers obtain the same build
+result as you did with:
+
+@example
+$ guix challenge @var{package}
+@end example
+
+@noindent
+where @var{package} is a package specification such as @code{guile@@2.0} or
+@code{glibc:debug}.
+
+The general syntax is:
+
+@example
+guix challenge @var{options} [@var{packages}@dots{}]
+@end example
+
+When a difference is found between the hash of a locally-built item and that
+of a server-provided substitute, or among substitutes provided by different
+servers, the command displays it as in the example above and its exit code
+is 2 (other non-zero exit codes denote other kinds of errors.)
+
+The one option that matters is:
+
+@table @code
+
+@item --substitute-urls=@var{urls}
+Consider @var{urls} the whitespace-separated list of substitute source URLs
+to compare to.
+
+@item --verbose
+@itemx -v

+
+If some of the items to be copied are already present on @var{host}, they

+
+The SSH connection is established using the Guile-SSH client, which is

+
+The key used to sign items that are sent must be accepted by the remote

+@quotation Note
+As of version @value{VERSION}, this tool is experimental.  The interface is
+subject to radical change in the future.
+@end quotation
+
+The purpose of @command{guix container} is to manipulate processes running
+within an isolated environment, commonly known as a ``container'', typically
+created by the @command{guix environment} (@pxref{Invoquer guix environment}) and @command{guix system container} (@pxref{Invoquer guix system}) commands.
+
+The general syntax is:
+
+@example
+guix container @var{action} @var{options}@dots{}
+@end example
+
+@var{action} specifies the operation to perform with a container, and
+@var{options} specifies the context-specific arguments for the action.
+
+The following actions are available:
+
+@table @code
+@item exec
+Execute a command within the context of a running container.
+
+The syntax is:
+
+@example
+guix container exec @var{pid} @var{program} @var{arguments}@dots{}
+@end example
+
+@var{pid} specifies the process ID of the running container.  @var{program}
+specifies an executable file name within the root file system of the
+container.  @var{arguments} are the additional options that will be passed
+to @var{program}.
+
+The following command launches an interactive login shell inside a GuixSD
+container, started by @command{guix system container}, and whose process ID
+is 9001:
+
+@example
+guix container exec 9001 /run/current-system/profile/bin/bash --login
+@end example
+
+Note that the @var{pid} cannot be the parent process of a container.  It
+must be PID 1 of the container or one of its child processes.

+Vous pouvez parfois grogner lorsque les substituts ne sont pas disponibles

+
+@cindex continuous integration, statistics
+As you can see, it reports the fraction of all the packages for which
+substitutes are available on the server---regardless of whether substitutes
+are enabled, and regardless of whether this server's signing key is
+authorized.  It also reports the size of the compressed archives (``nars'')
+provided by the server, the size the corresponding store items occupy in the
+store (assuming deduplication is turned off), and the server's throughput.
+The second part gives continuous integration (CI) statistics, if the server
+supports it.
+
+To achieve that, @command{guix weather} queries over HTTP(S) meta-data
+(@dfn{narinfos}) for all the relevant store items.  Like @command{guix
+challenge}, it ignores signatures on those substitutes, which is innocuous
+since the command only gathers statistics and cannot install those
+substitutes.
+
+Among other things, it is possible to query specific system types and
+specific package sets.  The available options are listed below.
+
+@table @code
+@item --substitute-urls=@var{urls}
+@var{urls} is the space-separated list of substitute server URLs to query.
+When this option is omitted, the default set of substitute servers is
+queried.
+
+@item --system=@var{system}
+@itemx -s @var{system}
+Query substitutes for @var{system}---e.g., @code{aarch64-linux}.  This
+option can be repeated, in which case @command{guix weather} will query
+substitutes for several system types.
+
+@item --manifest=@var{file}
+Instead of querying substitutes for all the packages, only ask for those
+specified in @var{file}.  @var{file} must contain a @dfn{manifest}, as with
+the @code{-m} option of @command{guix package} (@pxref{Invoquer guix package}).

+Guix comes with a distribution of the GNU system consisting entirely of free
+software@footnote{The term ``free'' here refers to the
+@url{http://www.gnu.org/philosophy/free-sw.html,freedom provided to users of
+that software}.}.  The distribution can be installed on its own
+(@pxref{Installation du système}), but it is also possible to install Guix as a
+package manager on top of an installed GNU/Linux system
+(@pxref{Installation}).  To distinguish between the two, we refer to the
+standalone distribution as the Guix System Distribution, or GuixSD.
+
+The distribution provides core GNU packages such as GNU libc, GCC, and
+Binutils, as well as many GNU and non-GNU applications.  The complete list
+of available packages can be browsed
+@url{http://www.gnu.org/software/guix/packages,on-line} or by running
+@command{guix package} (@pxref{Invoquer guix package}):
+
+@example
+guix package --list-available
+@end example
+
+Our goal is to provide a practical 100% free software distribution of
+Linux-based and other variants of GNU, with a focus on the promotion and
+tight integration of GNU components, and an emphasis on programs and tools
+that help users exert that freedom.

+@node Limitations
+@subsection Limitations
+
+As of version @value{VERSION}, the Guix System Distribution (GuixSD) is not
+production-ready.  It may contain bugs and lack important features.  Thus,
+if you are looking for a stable production system that respects your freedom
+as a computer user, a good solution at this point is to consider
+@url{http://www.gnu.org/distros/free-distros.html, one of the more
+established GNU/Linux distributions}.  We hope you can soon switch to the
+GuixSD without fear, of course.  In the meantime, you can also keep using
+your distribution and try out the package manager on top of it
+(@pxref{Installation}).
+
+Before you proceed with the installation, be aware of the following
+noteworthy limitations applicable to version @value{VERSION}:
+
+@itemize
+@item
+The installation process does not include a graphical user interface and
+requires familiarity with GNU/Linux (see the following subsections to get a
+feel of what that means.)
+
+@item
+Support for the Logical Volume Manager (LVM) is missing.
+
+@item
+More and more system services are provided (@pxref{Services}), but some may
+be missing.
+
+@item
+More than 6,500 packages are available, but you might occasionally find that
+a useful package is missing.
+
+@item
+GNOME, Xfce, LXDE, and Enlightenment are available (@pxref{Desktop
+Services}), as well as a number of X11 window managers.  However, some
+graphical applications may be missing, as well as KDE.
+@end itemize
+
+You have been warned! But more than a disclaimer, this is an invitation to
+report issues (and success stories!), and to join us in improving it.

+@node Considérations matérielles
+@subsection Considérations matérielles
+
+@cindex hardware support on GuixSD
+GNU@tie{}GuixSD focuses on respecting the user's computing freedom.  It
+builds around the kernel Linux-libre, which means that only hardware for
+which free software drivers and firmware exist is supported.  Nowadays, a
+wide range of off-the-shelf hardware is supported on GNU/Linux-libre---from
+keyboards to graphics cards to scanners and Ethernet controllers.
+Unfortunately, there are still areas where hardware vendors deny users
+control over their own computing, and such hardware is not supported on
+GuixSD.
+
+@cindex WiFi, hardware support
+One of the main areas where free drivers or firmware are lacking is WiFi
+devices.  WiFi devices known to work include those using Atheros chips
+(AR9271 and AR7010), which corresponds to the @code{ath9k} Linux-libre
+driver, and those using Broadcom/AirForce chips (BCM43xx with Wireless-Core
+Revision 5), which corresponds to the @code{b43-open} Linux-libre driver.
+Free firmware exists for both and is available out-of-the-box on GuixSD, as
+part of @var{%base-firmware} (@pxref{Référence de système d'exploitation,
+@code{firmware}}).
+
+@cindex RYF, Respects Your Freedom
+The @uref{https://www.fsf.org/, Free Software Foundation} runs
+@uref{https://www.fsf.org/ryf, @dfn{Respects Your Freedom}} (RYF), a
+certification program for hardware products that respect your freedom and
+your privacy and ensure that you have control over your device.  We
+encourage you to check the list of RYF-certified devices.
+
+Another useful resource is the @uref{https://www.h-node.org/, H-Node} web
+site.  It contains a catalog of hardware devices with information about
+their support in GNU/Linux.

+@node Installation depuis une clef USB ou un DVD
+@subsection Installation depuis une clef USB ou un DVD
+
+An ISO-9660 installation image that can be written to a USB stick or burnt
+to a DVD can be downloaded from
+@indicateurl{ftp://alpha.gnu.org/gnu/guix/guixsd-install-@value{VERSION}.@var{system}.iso.xz},
+where @var{system} is one of:
+
+@table @code
+@item x86_64-linux
+for a GNU/Linux system on Intel/AMD-compatible 64-bit CPUs;
+
+@item i686-linux
+for a 32-bit GNU/Linux system on Intel-compatible CPUs.
+@end table
+
+@c start duplication of authentication part from ``Binary Installation''
+Make sure to download the associated @file{.sig} file and to verify the
+authenticity of the image against it, along these lines:
+
+@example
+$ wget ftp://alpha.gnu.org/gnu/guix/guixsd-install-@value{VERSION}.@var{system}.iso.xz.sig
+$ gpg --verify guixsd-install-@value{VERSION}.@var{system}.iso.xz.sig
+@end example
+
+If that command fails because you do not have the required public key, then
+run this command to import it:
+
+@example
+$ gpg --keyserver pgp.mit.edu --recv-keys @value{OPENPGP-SIGNING-KEY-ID}
+@end example
+
+@noindent
+@c end duplication
+and rerun the @code{gpg --verify} command.
+
+This image contains the tools necessary for an installation.  It is meant to
+be copied @emph{as is} to a large-enough USB stick or DVD.
+
+@unnumberedsubsubsec Copying to a USB Stick
+
+To copy the image to a USB stick, follow these steps:
+
+@enumerate
+@item
+Decompress the image using the @command{xz} command:
+
+@example
+xz -d guixsd-install-@value{VERSION}.@var{system}.iso.xz
+@end example
+
+@item
+Insert a USB stick of 1@tie{}GiB or more into your machine, and determine
+its device name.  Assuming that the USB stick is known as @file{/dev/sdX},
+copy the image with:
+
+@example
+dd if=guixsd-install-@value{VERSION}.x86_64-linux.iso of=/dev/sdX
+sync
+@end example
+
+Access to @file{/dev/sdX} usually requires root privileges.
+@end enumerate
+
+@unnumberedsubsubsec Burning on a DVD
+
+To copy the image to a DVD, follow these steps:
+
+@enumerate
+@item
+Decompress the image using the @command{xz} command:
+
+@example
+xz -d guixsd-install-@value{VERSION}.@var{system}.iso.xz
+@end example
+
+@item
+Insert a blank DVD into your machine, and determine its device name.
+Assuming that the DVD drive is known as @file{/dev/srX}, copy the image
+with:
+
+@example
+growisofs -dvd-compat -Z /dev/srX=guixsd-install-@value{VERSION}.x86_64.iso
+@end example
+
+Access to @file{/dev/srX} usually requires root privileges.
+@end enumerate
+
+@unnumberedsubsubsec Booting
+
+Once this is done, you should be able to reboot the system and boot from the
+USB stick or DVD.  The latter usually requires you to get in the BIOS or
+UEFI boot menu, where you can choose to boot from the USB stick.
+
+@xref{Installer GuixSD dans une VM}, if, instead, you would like to install
+GuixSD in a virtual machine (VM).
+
+
+@node Préparer l'installation
+@subsection Préparer l'installation
+
+Once you have successfully booted your computer using the installation
+medium, you should end up with a root prompt.  Several console TTYs are
+configured and can be used to run commands as root.  TTY2 shows this
+documentation, browsable using the Info reader commands (@pxref{Top,,,
+info-stnd, Stand-alone GNU Info}).  The installation system runs the GPM
+mouse daemon, which allows you to select text with the left mouse button and
+to paste it with the middle button.
+
+@quotation Note
+Installation requires access to the Internet so that any missing
+dependencies of your system configuration can be downloaded.  See the
+``Networking'' section below.
+@end quotation
+
+The installation system includes many common tools needed for this task.
+But it is also a full-blown GuixSD system, which means that you can install
+additional packages, should you need it, using @command{guix package}
+(@pxref{Invoquer guix package}).
+
+@subsubsection Keyboard Layout
+
+@cindex keyboard layout
+The installation image uses the US qwerty keyboard layout.  If you want to
+change it, you can use the @command{loadkeys} command.  For example, the
+following command selects the Dvorak keyboard layout:
+
+@example
+loadkeys dvorak
+@end example
+
+See the files under @file{/run/current-system/profile/share/keymaps} for a
+list of available keyboard layouts.  Run @command{man loadkeys} for more
+information.
+
+@subsubsection Networking
+
+Run the following command see what your network interfaces are called:
+
+@example
+ifconfig -a
+@end example
+
+@noindent
+@dots{} or, using the GNU/Linux-specific @command{ip} command:
+
+@example
+ip a
+@end example
+
+@c http://cgit.freedesktop.org/systemd/systemd/tree/src/udev/udev-builtin-net_id.c#n20
+Wired interfaces have a name starting with @samp{e}; for example, the
+interface corresponding to the first on-board Ethernet controller is called
+@samp{eno1}.  Wireless interfaces have a name starting with @samp{w}, like
+@samp{w1p2s0}.
+
+@table @asis
+@item Wired connection
+To configure a wired network run the following command, substituting
+@var{interface} with the name of the wired interface you want to use.
+
+@example
+ifconfig @var{interface} up
+@end example
+
+@item Wireless connection
+@cindex wireless
+@cindex WiFi
+To configure wireless networking, you can create a configuration file for
+the @command{wpa_supplicant} configuration tool (its location is not
+important) using one of the available text editors such as @command{nano}:
+
+@example
+nano wpa_supplicant.conf
+@end example
+
+As an example, the following stanza can go to this file and will work for
+many wireless networks, provided you give the actual SSID and passphrase for
+the network you are connecting to:
+
+@example
+network=@{
+  ssid="@var{my-ssid}"
+  key_mgmt=WPA-PSK
+  psk="the network's secret passphrase"
+@}
+@end example
+
+Start the wireless service and run it in the background with the following
+command (substitute @var{interface} with the name of the network interface
+you want to use):
+
+@example
+wpa_supplicant -c wpa_supplicant.conf -i @var{interface} -B
+@end example
+
+Run @command{man wpa_supplicant} for more information.
+@end table
+
+@cindex DHCP
+At this point, you need to acquire an IP address.  On a network where IP
+addresses are automatically assigned @i{via} DHCP, you can run:
+
+@example
+dhclient -v @var{interface}
+@end example
+
+Try to ping a server to see if networking is up and running:
+
+@example
+ping -c 3 gnu.org
+@end example
+
+Setting up network access is almost always a requirement because the image
+does not contain all the software and tools that may be needed.
+
+@cindex installing over SSH
+If you want to, you can continue the installation remotely by starting an
+SSH server:
+
+@example
+herd start ssh-daemon
+@end example
+
+Make sure to either set a password with @command{passwd}, or configure
+OpenSSH public key authentication before logging in.
+
+@subsubsection Disk Partitioning
+
+Unless this has already been done, the next step is to partition, and then
+format the target partition(s).
+
+The installation image includes several partitioning tools, including Parted
+(@pxref{Overview,,, parted, GNU Parted User Manual}), @command{fdisk}, and
+@command{cfdisk}.  Run it and set up your disk with the partition layout you
+want:
+
+@example
+cfdisk
+@end example
+
+If your disk uses the GUID Partition Table (GPT) format and you plan to
+install BIOS-based GRUB (which is the default), make sure a BIOS Boot
+Partition is available (@pxref{BIOS installation,,, grub, GNU GRUB manual}).
+
+@cindex EFI, installation
+@cindex UEFI, installation
+@cindex ESP, EFI system partition
+If you instead wish to use EFI-based GRUB, a FAT32 @dfn{EFI System
+Partition} (ESP) is required.  This partition should be mounted at
+@file{/boot/efi} and must have the @code{esp} flag set.  E.g., for
+@command{parted}:
+
+@example
+parted /dev/sda set 1 esp on
+@end example
+
+Once you are done partitioning the target hard disk drive, you have to
+create a file system on the relevant partition(s)@footnote{Currently GuixSD
+only supports ext4 and btrfs file systems.  In particular, code that reads
+file system UUIDs and labels only works for these file system types.}.  For
+the ESP, if you have one and assuming it is @file{/dev/sda2}, run:
+
+@example
+mkfs.fat -F32 /dev/sda2
+@end example
+
+Preferably, assign file systems a label so that you can easily and reliably
+refer to them in @code{file-system} declarations (@pxref{Systèmes de fichiers}).
+This is typically done using the @code{-L} option of @command{mkfs.ext4} and
+related commands.  So, assuming the target root partition lives at
+@file{/dev/sda1}, a file system with the label @code{my-root} can be created
+with:
+
+@example
+mkfs.ext4 -L my-root /dev/sda1
+@end example
+
+@cindex encrypted disk
+If you are instead planning to encrypt the root partition, you can use the
+Cryptsetup/LUKS utilities to do that (see @inlinefmtifelse{html,
+@uref{https://linux.die.net/man/8/cryptsetup, @code{man cryptsetup}},
+@code{man cryptsetup}} for more information.)  Assuming you want to store
+the root partition on @file{/dev/sda1}, the command sequence would be along
+these lines:
+
+@example
+cryptsetup luksFormat /dev/sda1
+cryptsetup open --type luks /dev/sda1 my-partition
+mkfs.ext4 -L my-root /dev/mapper/my-partition
+@end example
+
+Once that is done, mount the target file system under @file{/mnt} with a
+command like (again, assuming @code{my-root} is the label of the root file
+system):
+
+@example
+mount LABEL=my-root /mnt
+@end example
+
+Also mount any other file systems you would like to use on the target system
+relative to this path.  If you have @file{/boot} on a separate partition for
+example, mount it at @file{/mnt/boot} now so it is found by @code{guix
+system init} afterwards.
+
+Finally, if you plan to use one or more swap partitions (@pxref{Memory
+Concepts, swap space,, libc, The GNU C Library Reference Manual}), make sure
+to initialize them with @command{mkswap}.  Assuming you have one swap
+partition on @file{/dev/sda2}, you would run:
+
+@example
+mkswap /dev/sda2
+swapon /dev/sda2
+@end example
+
+Alternatively, you may use a swap file.  For example, assuming that in the
+new system you want to use the file @file{/swapfile} as a swap file, you
+would run@footnote{This example will work for many types of file systems
+(e.g., ext4).  However, for copy-on-write file systems (e.g., btrfs), the
+required steps may be different.  For details, see the manual pages for
+@command{mkswap} and @command{swapon}.}:
+
+@example
+# This is 10 GiB of swap space.  Adjust "count" to change the size.
+dd if=/dev/zero of=/mnt/swapfile bs=1MiB count=10240
+# For security, make the file readable and writable only by root.
+chmod 600 /mnt/swapfile
+mkswap /mnt/swapfile
+swapon /mnt/swapfile
+@end example
+
+Note that if you have encrypted the root partition and created a swap file
+in its file system as described above, then the encryption also protects the

+
+With the target partitions ready and the target root mounted on @file{/mnt},
+we're ready to go.  First, run:
+
+@example
+herd start cow-store /mnt
+@end example
+
+This makes @file{/gnu/store} copy-on-write, such that packages added to it
+during the installation phase are written to the target disk on @file{/mnt}
+rather than kept in memory.  This is necessary because the first phase of
+the @command{guix system init} command (see below) entails downloads or
+builds to @file{/gnu/store} which, initially, is an in-memory file system.
+
+Next, you have to edit a file and provide the declaration of the operating
+system to be installed.  To that end, the installation system comes with
+three text editors.  We recommend GNU nano (@pxref{Top,,, nano, GNU nano
+Manual}), which supports syntax highlighting and parentheses matching; other
+editors include GNU Zile (an Emacs clone), and nvi (a clone of the original
+BSD @command{vi} editor).  We strongly recommend storing that file on the
+target root file system, say, as @file{/mnt/etc/config.scm}.  Failing to do
+that, you will have lost your configuration file once you have rebooted into
+the newly-installed system.
+
+@xref{Utiliser le système de configuration}, for an overview of the configuration
+file.  The example configurations discussed in that section are available
+under @file{/etc/configuration} in the installation image.  Thus, to get
+started with a system configuration providing a graphical display server (a
+``desktop'' system), you can run something along these lines:
+
+@example
+# mkdir /mnt/etc
+# cp /etc/configuration/desktop.scm /mnt/etc/config.scm
+# nano /mnt/etc/config.scm
+@end example
+
+You should pay attention to what your configuration file contains, and in
+particular:
+
+@itemize
+@item
+Make sure the @code{bootloader-configuration} form refers to the target you
+want to install GRUB on.  It should mention @code{grub-bootloader} if you
+are installing GRUB in the legacy way, or @code{grub-efi-bootloader} for
+newer UEFI systems.  For legacy systems, the @code{target} field names a
+device, like @code{/dev/sda}; for UEFI systems it names a path to a mounted
+EFI partition, like @code{/boot/efi}, and do make sure the path is actually
+mounted.
+
+@item
+Be sure that your file system labels match the value of their respective
+@code{device} fields in your @code{file-system} configuration, assuming your
+@code{file-system} configuration sets the value of @code{title} to
+@code{'label}.
+
+@item
+If there are encrypted or RAID partitions, make sure to add a
+@code{mapped-devices} field to describe them (@pxref{Périphériques mappés}).
+@end itemize
+
+Once you are done preparing the configuration file, the new system must be
+initialized (remember that the target root file system is mounted under
+@file{/mnt}):
+
+@example
+guix system init /mnt/etc/config.scm /mnt
+@end example
+
+@noindent
+This copies all the necessary files and installs GRUB on @file{/dev/sdX},
+unless you pass the @option{--no-bootloader} option.  For more information,
+@pxref{Invoquer guix system}.  This command may trigger downloads or builds
+of missing packages, which can take some time.
+
+Once that command has completed---and hopefully succeeded!---you can run
+@command{reboot} and boot into the new system.  The @code{root} password in
+the new system is initially empty; other users' passwords need to be
+initialized by running the @command{passwd} command as @code{root}, unless
+your configuration specifies otherwise (@pxref{user-account-password, user
+account passwords}).
+
+@cindex upgrading GuixSD
+From then on, you can update GuixSD whenever you want by running
+@command{guix pull} as @code{root} (@pxref{Invoquer guix pull}), and then
+running @command{guix system reconfigure} to build a new system generation
+with the latest packages and services (@pxref{Invoquer guix system}).  We
+recommend doing that regularly so that your system includes the latest
+security updates (@pxref{Mises à jour de sécurité}).

+Join us on @code{#guix} on the Freenode IRC network or on

+@cindex VPS (virtual private server)
+If you'd like to install GuixSD in a virtual machine (VM) or on a virtual
+private server (VPS) rather than on your beloved machine, this section is
+for you.
+
+To boot a @uref{http://qemu.org/,QEMU} VM for installing GuixSD in a disk
+image, follow these steps:
+
+@enumerate
+@item
+First, retrieve and decompress the GuixSD installation image as described
+previously (@pxref{Installation depuis une clef USB ou un DVD}).
+
+@item
+Create a disk image that will hold the installed system.  To make a
+qcow2-formatted disk image, use the @command{qemu-img} command:
+
+@example
+qemu-img create -f qcow2 guixsd.img 50G
+@end example
+
+The resulting file will be much smaller than 50 GB (typically less than 1
+MB), but it will grow as the virtualized storage device is filled up.
+
+@item
+Boot the USB installation image in an VM:
+
+@example
+qemu-system-x86_64 -m 1024 -smp 1 \
+  -net user -net nic,model=virtio -boot menu=on \
+  -drive file=guixsd-install-@value{VERSION}.@var{system}.iso \
+  -drive file=guixsd.img
+@end example
+
+The ordering of the drives matters.
+
+In the VM console, quickly press the @kbd{F12} key to enter the boot menu.
+Then press the @kbd{2} key and the @kbd{RET} key to validate your selection.
+
+@item
+You're now root in the VM, proceed with the installation process.
+@xref{Préparer l'installation}, and follow the instructions.
+@end enumerate
+
+Once installation is complete, you can boot the system that's on your
+@file{guixsd.img} image.  @xref{Lancer GuixSD dans une VM}, for how to do that.

+@node Configuration système
+@section Configuration système
+
+@cindex system configuration
+The Guix System Distribution supports a consistent whole-system
+configuration mechanism.  By that we mean that all aspects of the global
+system configuration---such as the available system services, timezone and
+locale settings, user accounts---are declared in a single place.  Such a
+@dfn{system configuration} can be @dfn{instantiated}---i.e., effected.
+
+@c Yes, we're talking of Puppet, Chef, & co. here.  ↑
+One of the advantages of putting all the system configuration under the
+control of Guix is that it supports transactional system upgrades, and makes
+it possible to roll back to a previous system instantiation, should
+something go wrong with the new one (@pxref{Fonctionnalités}).  Another advantage
+is that it makes it easy to replicate the exact same configuration across
+different machines, or at different points in time, without having to resort
+to additional administration tools layered on top of the own tools of the
+system.
+
+This section describes this mechanism.  First we focus on the system
+administrator's viewpoint---explaining how the system is configured and
+instantiated.  Then we show how this mechanism can be extended, for instance
+to support new system services.

+@node Utiliser le système de configuration
+@subsection Utiliser le système de configuration
+
+The operating system is configured by providing an @code{operating-system}
+declaration in a file that can then be passed to the @command{guix system}
+command (@pxref{Invoquer guix system}).  A simple setup, with the default
+system services, the default Linux-Libre kernel, initial RAM disk, and boot
+loader looks like this:
+
+@findex operating-system
+@lisp
+@include os-config-bare-bones.texi
+@end lisp
+
+This example should be self-describing.  Some of the fields defined above,
+such as @code{host-name} and @code{bootloader}, are mandatory.  Others, such
+as @code{packages} and @code{services}, can be omitted, in which case they
+get a default value.
+
+Below we discuss the effect of some of the most important fields
+(@pxref{Référence de système d'exploitation}, for details about all the available
+fields), and how to @dfn{instantiate} the operating system using
+@command{guix system}.
+
+@unnumberedsubsubsec Globally-Visible Packages
+
+@vindex %base-packages
+The @code{packages} field lists packages that will be globally visible on
+the system, for all user accounts---i.e., in every user's @code{PATH}
+environment variable---in addition to the per-user profiles (@pxref{Invoquer guix package}).  The @var{%base-packages} variable provides all the tools
+one would expect for basic user and administrator tasks---including the GNU
+Core Utilities, the GNU Networking Utilities, the GNU Zile lightweight text
+editor, @command{find}, @command{grep}, etc.  The example above adds
+GNU@tie{}Screen and OpenSSH to those, taken from the @code{(gnu packages
+screen)} and @code{(gnu packages ssh)} modules (@pxref{Modules de paquets}).
+The @code{(list package output)} syntax can be used to add a specific output
+of a package:
+
+@lisp
+(use-modules (gnu packages))
+(use-modules (gnu packages dns))
+
+(operating-system
+  ;; ...
+  (packages (cons (list bind "utils")
+                  %base-packages)))
+@end lisp
+
+@findex specification->package
+Referring to packages by variable name, like @code{bind} above, has the
+advantage of being unambiguous; it also allows typos and such to be
+diagnosed right away as ``unbound variables''.  The downside is that one
+needs to know which module defines which package, and to augment the
+@code{use-package-modules} line accordingly.  To avoid that, one can use the
+@code{specification->package} procedure of the @code{(gnu packages)} module,
+which returns the best package for a given name or name and version:
+
+@lisp
+(use-modules (gnu packages))
+
+(operating-system
+  ;; ...
+  (packages (append (map specification->package
+                         '("tcpdump" "htop" "gnupg@@2.0"))
+                    %base-packages)))
+@end lisp
+
+@unnumberedsubsubsec System Services
+
+@cindex services
+@vindex %base-services
+The @code{services} field lists @dfn{system services} to be made available
+when the system starts (@pxref{Services}).  The @code{operating-system}
+declaration above specifies that, in addition to the basic services, we want
+the @command{lshd} secure shell daemon listening on port 2222
+(@pxref{Networking Services, @code{lsh-service}}).  Under the hood,
+@code{lsh-service} arranges so that @code{lshd} is started with the right
+command-line options, possibly with supporting configuration files generated
+as needed (@pxref{Définir des services}).
+
+@cindex customization, of services
+@findex modify-services
+Occasionally, instead of using the base services as is, you will want to
+customize them.  To do this, use @code{modify-services} (@pxref{Référence de service, @code{modify-services}}) to modify the list.
+
+For example, suppose you want to modify @code{guix-daemon} and Mingetty (the
+console log-in) in the @var{%base-services} list (@pxref{Services de base,
+@code{%base-services}}).  To do that, you can write the following in your
+operating system declaration:
+
+@lisp
+(define %my-services
+  ;; My very own list of services.
+  (modify-services %base-services
+    (guix-service-type config =>
+                       (guix-configuration
+                        (inherit config)
+                        (use-substitutes? #f)
+                        (extra-options '("--gc-keep-derivations"))))
+    (mingetty-service-type config =>
+                           (mingetty-configuration
+                            (inherit config)))))
+
+(operating-system
+  ;; @dots{}
+  (services %my-services))
+@end lisp
+
+This changes the configuration---i.e., the service parameters---of the
+@code{guix-service-type} instance, and that of all the
+@code{mingetty-service-type} instances in the @var{%base-services} list.
+Observe how this is accomplished: first, we arrange for the original
+configuration to be bound to the identifier @code{config} in the @var{body},
+and then we write the @var{body} so that it evaluates to the desired
+configuration.  In particular, notice how we use @code{inherit} to create a
+new configuration which has the same values as the old configuration, but
+with a few modifications.
+
+@cindex encrypted disk
+The configuration for a typical ``desktop'' usage, with an encrypted root
+partition, the X11 display server, GNOME and Xfce (users can choose which of
+these desktop environments to use at the log-in screen by pressing
+@kbd{F1}), network management, power management, and more, would look like
+this:
+
+@lisp
+@include os-config-desktop.texi
+@end lisp
+
+@cindex UEFI
+A graphical UEFI system with a choice of lightweight window managers instead
+of full-blown desktop environments would look like this:
+
+@lisp
+@include os-config-lightweight-desktop.texi
+@end lisp
+
+This example refers to the @file{/boot/efi} file system by its UUID,
+@code{1234-ABCD}.  Replace this UUID with the right UUID on your system, as
+returned by the @command{blkid} command.
+
+@xref{Desktop Services}, for the exact list of services provided by
+@var{%desktop-services}.  @xref{Certificats X.509}, for background
+information about the @code{nss-certs} package that is used here.
+
+Again, @var{%desktop-services} is just a list of service objects.  If you
+want to remove services from there, you can do so using the procedures for
+list filtering (@pxref{SRFI-1 Filtering and Partitioning,,, guile, GNU Guile
+Reference Manual}).  For instance, the following expression returns a list
+that contains all the services in @var{%desktop-services} minus the Avahi
+service:
+
+@example
+(remove (lambda (service)
+          (eq? (service-kind service) avahi-service-type))
+        %desktop-services)
+@end example
+
+@unnumberedsubsubsec Instantiating the System
+
+Assuming the @code{operating-system} declaration is stored in the
+@file{my-system-config.scm} file, the @command{guix system reconfigure
+my-system-config.scm} command instantiates that configuration, and makes it
+the default GRUB boot entry (@pxref{Invoquer guix system}).
+
+The normal way to change the system configuration is by updating this file
+and re-running @command{guix system reconfigure}.  One should never have to
+touch files in @file{/etc} or to run commands that modify the system state
+such as @command{useradd} or @command{grub-install}.  In fact, you must
+avoid that since that would not only void your warranty but also prevent you
+from rolling back to previous versions of your system, should you ever need
+to.
+
+@cindex roll-back, of the operating system
+Speaking of roll-back, each time you run @command{guix system reconfigure},
+a new @dfn{generation} of the system is created---without modifying or
+deleting previous generations.  Old system generations get an entry in the
+bootloader boot menu, allowing you to boot them in case something went wrong
+with the latest generation.  Reassuring, no? The @command{guix system
+list-generations} command lists the system generations available on disk.
+It is also possible to roll back the system via the commands @command{guix
+system roll-back} and @command{guix system switch-generation}.
+
+Although the command @command{guix system reconfigure} will not modify
+previous generations, must take care when the current generation is not the
+latest (e.g., after invoking @command{guix system roll-back}), since the
+operation might overwrite a later generation (@pxref{Invoquer guix system}).
+
+@unnumberedsubsubsec The Programming Interface
+
+At the Scheme level, the bulk of an @code{operating-system} declaration is
+instantiated with the following monadic procedure (@pxref{La monad du dépôt}):
+
+@deffn {Monadic Procedure} operating-system-derivation os
+Return a derivation that builds @var{os}, an @code{operating-system} object
+(@pxref{Dérivations}).
+
+The output of the derivation is a single directory that refers to all the
+packages, configuration files, and other supporting files needed to
+instantiate @var{os}.
+@end deffn
+
+This procedure is provided by the @code{(gnu system)} module.  Along with
+@code{(gnu services)} (@pxref{Services}), this module contains the guts of
+GuixSD.  Make sure to visit it!

+@deftp {Data Type} file-system
+Objects of this type represent file systems to be mounted.  They contain the
+following members:
+
+@table @asis
+@item @code{type}
+This is a string specifying the type of the file system---e.g.,
+@code{"ext4"}.
+
+@item @code{mount-point}
+This designates the place where the file system is to be mounted.
+
+@item @code{device}
+This names the ``source'' of the file system.  By default it is the name of
+a node under @file{/dev}, but its meaning depends on the @code{title} field
+described below.
+
+@item @code{title} (default: @code{'device})
+This is a symbol that specifies how the @code{device} field is to be
+interpreted.
+
+When it is the symbol @code{device}, then the @code{device} field is
+interpreted as a file name; when it is @code{label}, then @code{device} is
+interpreted as a file system label name; when it is @code{uuid},
+@code{device} is interpreted as a file system unique identifier (UUID).
+
+UUIDs may be converted from their string representation (as shown by the
+@command{tune2fs -l} command) using the @code{uuid} form@footnote{The
+@code{uuid} form expects 16-byte UUIDs as defined in
+@uref{https://tools.ietf.org/html/rfc4122, RFC@tie{}4122}.  This is the form
+of UUID used by the ext2 family of file systems and others, but it is
+different from ``UUIDs'' found in FAT file systems, for instance.}, like
+this:
+
+@example
+(file-system
+  (mount-point "/home")
+  (type "ext4")
+  (title 'uuid)
+  (device (uuid "4dab5feb-d176-45de-b287-9b0a6e4c01cb")))
+@end example
+
+The @code{label} and @code{uuid} options offer a way to refer to file
+systems without having to hard-code their actual device name@footnote{Note
+that, while it is tempting to use @file{/dev/disk/by-uuid} and similar
+device names to achieve the same result, this is not recommended: These
+special device nodes are created by the udev daemon and may be unavailable
+at the time the device is mounted.}.
+
+However, when the source of a file system is a mapped device (@pxref{Périphériques mappés}), its @code{device} field @emph{must} refer to the mapped device
+name---e.g., @file{/dev/mapper/root-partition}---and consequently
+@code{title} must be set to @code{'device}.  This is required so that the
+system knows that mounting the file system depends on having the
+corresponding device mapping established.
+
+@item @code{flags} (default: @code{'()})
+This is a list of symbols denoting mount flags.  Recognized flags include
+@code{read-only}, @code{bind-mount}, @code{no-dev} (disallow access to
+special files), @code{no-suid} (ignore setuid and setgid bits), and
+@code{no-exec} (disallow program execution.)
+
+@item @code{options} (default: @code{#f})
+This is either @code{#f}, or a string denoting mount options.
+
+@item @code{mount?} (default: @code{#t})
+This value indicates whether to automatically mount the file system when the
+system is brought up.  When set to @code{#f}, the file system gets an entry
+in @file{/etc/fstab} (read by the @command{mount} command) but is not
+automatically mounted.
+
+@item @code{needed-for-boot?} (default: @code{#f})
+This Boolean value indicates whether the file system is needed when
+booting.  If that is true, then the file system is mounted when the initial
+RAM disk (initrd) is loaded.  This is always the case, for instance, for the
+root file system.
+
+@item @code{check?} (default: @code{#t})
+This Boolean indicates whether the file system needs to be checked for
+errors before being mounted.
+
+@item @code{create-mount-point?} (default: @code{#f})
+When true, the mount point is created if it does not exist yet.
+
+@item @code{dependencies} (default: @code{'()})
+This is a list of @code{<file-system>} or @code{<mapped-device>} objects
+representing file systems that must be mounted or mapped devices that must
+be opened before (and unmounted or closed after) this one.
+
+As an example, consider a hierarchy of mounts: @file{/sys/fs/cgroup} is a
+dependency of @file{/sys/fs/cgroup/cpu} and @file{/sys/fs/cgroup/memory}.
+
+Another example is a file system that depends on a mapped device, for
+example for an encrypted partition (@pxref{Périphériques mappés}).

+@cindex device mapping
+@cindex mapped devices
+The Linux kernel has a notion of @dfn{device mapping}: a block device, such
+as a hard disk partition, can be @dfn{mapped} into another device, usually
+in @code{/dev/mapper/}, with additional processing over the data that flows
+through it@footnote{Note that the GNU@tie{}Hurd makes no difference between
+the concept of a ``mapped device'' and that of a file system: both boil down
+to @emph{translating} input/output operations made on a file to operations
+on its backing store.  Thus, the Hurd implements mapped devices, like file
+systems, using the generic @dfn{translator} mechanism (@pxref{Translators,,,
+hurd, The GNU Hurd Reference Manual}).}.  A typical example is encryption
+device mapping: all writes to the mapped device are encrypted, and all reads
+are deciphered, transparently.  Guix extends this notion by considering any
+device or set of devices that are @dfn{transformed} in some way to create a
+new device; for instance, RAID devices are obtained by @dfn{assembling}
+several other devices, such as hard disks or partitions, into a new one that
+behaves as one partition.  Other examples, not yet implemented, are LVM
+logical volumes.
+
+Mapped devices are declared using the @code{mapped-device} form, defined as
+follows; for examples, see below.
+
+@deftp {Data Type} mapped-device
+Objects of this type represent device mappings that will be made when the
+system boots up.
+
+@table @code
+@item source
+This is either a string specifying the name of the block device to be
+mapped, such as @code{"/dev/sda3"}, or a list of such strings when several
+devices need to be assembled for creating a new one.
+
+@item target
+This string specifies the name of the resulting mapped device.  For kernel
+mappers such as encrypted devices of type @code{luks-device-mapping},
+specifying @code{"my-partition"} leads to the creation of the
+@code{"/dev/mapper/my-partition"} device.  For RAID devices of type
+@code{raid-device-mapping}, the full device name such as @code{"/dev/md0"}
+needs to be given.
+
+@item type
+This must be a @code{mapped-device-kind} object, which specifies how
+@var{source} is mapped to @var{target}.
+@end table
+@end deftp
+
+@defvr {Scheme Variable} luks-device-mapping
+This defines LUKS block device encryption using the @command{cryptsetup}
+command from the package with the same name.  It relies on the
+@code{dm-crypt} Linux kernel module.
+@end defvr
+
+@defvr {Scheme Variable} raid-device-mapping
+This defines a RAID device, which is assembled using the @code{mdadm}
+command from the package with the same name.  It requires a Linux kernel
+module for the appropriate RAID level to be loaded, such as @code{raid456}
+for RAID-4, RAID-5 or RAID-6, or @code{raid10} for RAID-10.
+@end defvr
+
+@cindex disk encryption
+@cindex LUKS
+The following example specifies a mapping from @file{/dev/sda3} to
+@file{/dev/mapper/home} using LUKS---the
+@url{https://gitlab.com/cryptsetup/cryptsetup,Linux Unified Key Setup}, a
+standard mechanism for disk encryption.  The @file{/dev/mapper/home} device
+can then be used as the @code{device} of a @code{file-system} declaration
+(@pxref{Systèmes de fichiers}).
+
+@example
+(mapped-device
+  (source "/dev/sda3")
+  (target "home")
+  (type luks-device-mapping))
+@end example
+
+Alternatively, to become independent of device numbering, one may obtain the
+LUKS UUID (@dfn{unique identifier}) of the source device by a command like:
+
+@example
+cryptsetup luksUUID /dev/sda3
+@end example
+
+and use it as follows:
+
+@example
+(mapped-device
+  (source (uuid "cb67fc72-0d54-4c88-9d4b-b225f30b0f44"))
+  (target "home")
+  (type luks-device-mapping))
+@end example
+
+@cindex swap encryption
+It is also desirable to encrypt swap space, since swap space may contain
+sensitive data.  One way to accomplish that is to use a swap file in a file
+system on a device mapped via LUKS encryption.  In this way, the swap file
+is encrypted because the entire device is encrypted.  @xref{Préparer l'installation,,Disk Partitioning}, for an example.
+
+A RAID device formed of the partitions @file{/dev/sda1} and @file{/dev/sdb1}
+may be declared as follows:
+
+@example
+(mapped-device
+  (source (list "/dev/sda1" "/dev/sdb1"))
+  (target "/dev/md0")
+  (type raid-device-mapping))
+@end example
+
+The @file{/dev/md0} device can then be used as the @code{device} of a
+@code{file-system} declaration (@pxref{Systèmes de fichiers}).  Note that the RAID
+level need not be given; it is chosen during the initial creation and
+formatting of the RAID device and is determined automatically later.

+@node Comptes utilisateurs
+@subsection Comptes utilisateurs
+
+@cindex users
+@cindex accounts
+@cindex user accounts
+User accounts and groups are entirely managed through the
+@code{operating-system} declaration.  They are specified with the
+@code{user-account} and @code{user-group} forms:
+
+@example
+(user-account
+  (name "alice")
+  (group "users")
+  (supplementary-groups '("wheel"   ;allow use of sudo, etc.

+  (comment "Bob's sister")
+  (home-directory "/home/alice"))
+@end example
+
+When booting or upon completion of @command{guix system reconfigure}, the
+system ensures that only the user accounts and groups specified in the
+@code{operating-system} declaration exist, and with the specified
+properties.  Thus, account or group creations or modifications made by
+directly invoking commands such as @command{useradd} are lost upon
+reconfiguration or reboot.  This ensures that the system remains exactly as
+declared.
+
+@deftp {Data Type} user-account
+Objects of this type represent user accounts.  The following members may be
+specified:
+
+@table @asis
+@item @code{name}
+The name of the user account.
+
+@item @code{group}
+@cindex groups
+This is the name (a string) or identifier (a number) of the user group this
+account belongs to.
+
+@item @code{supplementary-groups} (default: @code{'()})
+Optionally, this can be defined as a list of group names that this account
+belongs to.
+
+@item @code{uid} (default: @code{#f})
+This is the user ID for this account (a number), or @code{#f}.  In the
+latter case, a number is automatically chosen by the system when the account
+is created.
+
+@item @code{comment} (default: @code{""})
+A comment about the account, such as the account owner's full name.
+
+@item @code{home-directory}
+This is the name of the home directory for the account.
+
+@item @code{create-home-directory?} (default: @code{#t})
+Indicates whether the home directory of this account should be created if it
+does not exist yet.
+
+@item @code{shell} (default: Bash)
+This is a G-expression denoting the file name of a program to be used as the
+shell (@pxref{G-Expressions}).
+
+@item @code{system?} (default: @code{#f})
+This Boolean value indicates whether the account is a ``system'' account.
+System accounts are sometimes treated specially; for instance, graphical
+login managers do not list them.
+
+@anchor{user-account-password}
+@item @code{password} (default: @code{#f})
+You would normally leave this field to @code{#f}, initialize user passwords
+as @code{root} with the @command{passwd} command, and then let users change
+it with @command{passwd}.  Passwords set with @command{passwd} are of course
+preserved across reboot and reconfiguration.
+
+If you @emph{do} want to have a preset password for an account, then this
+field must contain the encrypted password, as a string.  @xref{crypt,,,
+libc, The GNU C Library Reference Manual}, for more information on password
+encryption, and @ref{Encryption,,, guile, GNU Guile Reference Manual}, for
+information on Guile's @code{crypt} procedure.
+
+@end table
+@end deftp
+
+@cindex groups
+User group declarations are even simpler:
+
+@example
+(user-group (name "students"))
+@end example
+
+@deftp {Data Type} user-group
+This type is for, well, user groups.  There are just a few fields:
+
+@table @asis
+@item @code{name}
+The name of the group.
+
+@item @code{id} (default: @code{#f})
+The group identifier (a number).  If @code{#f}, a new number is
+automatically allocated when the group is created.
+
+@item @code{system?} (default: @code{#f})
+This Boolean value indicates whether the group is a ``system'' group.
+System groups have low numerical IDs.
+
+@item @code{password} (default: @code{#f})
+What, user groups can have a password? Well, apparently yes.  Unless
+@code{#f}, this field specifies the password of the group.
+
+@end table
+@end deftp
+
+For convenience, a variable lists all the basic user groups one may expect:
+
+@defvr {Scheme Variable} %base-groups
+This is the list of basic user groups that users and/or packages expect to
+be present on the system.  This includes groups such as ``root'', ``wheel'',
+and ``users'', as well as groups used to control access to specific devices
+such as ``audio'', ``disk'', and ``cdrom''.
+@end defvr
+
+@defvr {Scheme Variable} %base-user-accounts
+This is the list of basic system accounts that programs may expect to find
+on a GNU/Linux system, such as the ``nobody'' account.

+and is automatically added whether or not it is specified.

+@node Régionalisation
+@subsection Régionalisation
+
+@cindex locale
+A @dfn{locale} defines cultural conventions for a particular language and
+region of the world (@pxref{Régionalisation,,, libc, The GNU C Library Reference
+Manual}).  Each locale has a name that typically has the form
+@code{@var{language}_@var{territory}.@var{codeset}}---e.g.,
+@code{fr_LU.utf8} designates the locale for the French language, with
+cultural conventions from Luxembourg, and using the UTF-8 encoding.
+
+@cindex locale definition
+Usually, you will want to specify the default locale for the machine using
+the @code{locale} field of the @code{operating-system} declaration
+(@pxref{Référence de système d'exploitation, @code{locale}}).
+
+The selected locale is automatically added to the @dfn{locale definitions}
+known to the system if needed, with its codeset inferred from its
+name---e.g., @code{bo_CN.utf8} will be assumed to use the @code{UTF-8}
+codeset.  Additional locale definitions can be specified in the
+@code{locale-definitions} slot of @code{operating-system}---this is useful,
+for instance, if the codeset could not be inferred from the locale name.
+The default set of locale definitions includes some widely used locales, but
+not all the available locales, in order to save space.
+
+For instance, to add the North Frisian locale for Germany, the value of that
+field may be:
+
+@example
+(cons (locale-definition
+        (name "fy_DE.utf8") (source "fy_DE"))
+      %default-locale-definitions)
+@end example
+
+Likewise, to save space, one might want @code{locale-definitions} to list
+only the locales that are actually used, as in:
+
+@example
+(list (locale-definition
+        (name "ja_JP.eucjp") (source "ja_JP")
+        (charset "EUC-JP")))
+@end example
+
+@vindex LOCPATH
+The compiled locale definitions are available at
+@file{/run/current-system/locale/X.Y}, where @code{X.Y} is the libc version,
+which is the default location where the GNU@tie{}libc provided by Guix looks
+for locale data.  This can be overridden using the @code{LOCPATH}
+environment variable (@pxref{locales-and-locpath, @code{LOCPATH} and locale
+packages}).
+
+The @code{locale-definition} form is provided by the @code{(gnu system

+
+@deftp {Data Type} locale-definition
+This is the data type of a locale definition.
+
+@table @asis
+
+@item @code{name}
+The name of the locale.  @xref{Locale Names,,, libc, The GNU C Library
+Reference Manual}, for more information on locale names.
+
+@item @code{source}
+The name of the source for that locale.  This is typically the
+@code{@var{language}_@var{territory}} part of the locale name.
+
+@item @code{charset} (default: @code{"UTF-8"})
+The ``character set'' or ``code set'' for that locale,

+
+@cindex locale name
+@cindex normalized codeset in locale names
+These locale definitions use the @dfn{normalized codeset} for the part that
+follows the dot in the name (@pxref{Using gettextized software, normalized

+has @code{uk_UA.utf8} but @emph{not}, say, @code{uk_UA.UTF-8}.
+@end defvr
+
+@subsubsection Locale Data Compatibility Considerations
+
+@cindex incompatibility, of locale data
+@code{operating-system} declarations provide a @code{locale-libcs} field to
+specify the GNU@tie{}libc packages that are used to compile locale
+declarations (@pxref{Référence de système d'exploitation}).  ``Why would I care?'',
+you may ask.  Well, it turns out that the binary format of locale data is
+occasionally incompatible from one libc version to another.
+
+@c See <https://sourceware.org/ml/libc-alpha/2015-09/msg00575.html>
+@c and <https://lists.gnu.org/archive/html/guix-devel/2015-08/msg00737.html>.
+For instance, a program linked against libc version 2.21 is unable to read
+locale data produced with libc 2.22; worse, that program @emph{aborts}
+instead of simply ignoring the incompatible locale data@footnote{Versions
+2.23 and later of GNU@tie{}libc will simply skip the incompatible locale
+data, which is already an improvement.}.  Similarly, a program linked
+against libc 2.22 can read most, but not all, of the locale data from libc
+2.21 (specifically, @code{LC_COLLATE} data is incompatible); thus calls to
+@code{setlocale} may fail, but programs will not abort.
+
+The ``problem'' in GuixSD is that users have a lot of freedom: They can
+choose whether and when to upgrade software in their profiles, and might be
+using a libc version different from the one the system administrator used to
+build the system-wide locale data.
+
+Fortunately, unprivileged users can also install their own locale data and
+define @var{GUIX_LOCPATH} accordingly (@pxref{locales-and-locpath,
+@code{GUIX_LOCPATH} and locale packages}).
+
+Still, it is best if the system-wide locale data at
+@file{/run/current-system/locale} is built for all the libc versions
+actually in use on the system, so that all the programs can access it---this
+is especially crucial on a multi-user system.  To do that, the administrator
+can specify several libc packages in the @code{locale-libcs} field of
+@code{operating-system}:
+
+@example
+(use-package-modules base)
+
+(operating-system
+  ;; @dots{}
+  (locale-libcs (list glibc-2.21 (canonical-package glibc))))
+@end example
+
+This example would lead to a system containing locale definitions for both
+libc 2.21 and the current version of libc in
+@file{/run/current-system/locale}.
+
+
+@node Services
+@subsection Services
+
+@cindex system services
+An important part of preparing an @code{operating-system} declaration is
+listing @dfn{system services} and their configuration (@pxref{Utiliser le système de configuration}).  System services are typically daemons launched when
+the system boots, or other actions needed at that time---e.g., configuring
+network access.
+
+GuixSD has a broad definition of ``service'' (@pxref{Composition de services}),
+but many services are managed by the GNU@tie{}Shepherd (@pxref{Services Shepherd}).  On a running system, the @command{herd} command allows you to
+list the available services, show their status, start and stop them, or do
+other specific operations (@pxref{Jump Start,,, shepherd, The GNU Shepherd
+Manual}).  For example:
+
+@example
+# herd status
+@end example
+
+The above command, run as @code{root}, lists the currently defined
+services.  The @command{herd doc} command shows a synopsis of the given
+service:
+
+@example
+# herd doc nscd
+Run libc's name service cache daemon (nscd).
+@end example
+
+The @command{start}, @command{stop}, and @command{restart} sub-commands have
+the effect you would expect.  For instance, the commands below stop the nscd
+service and restart the Xorg display server:
+
+@example
+# herd stop nscd
+Service nscd has been stopped.
+# herd restart xorg-server
+Service xorg-server has been stopped.
+Service xorg-server has been started.
+@end example
+
+The following sections document the available services, starting with the
+core services, that may be used in an @code{operating-system} declaration.

+This is the service that sets up ``special files'' such as @file{/bin/sh};
+an instance of it is part of @code{%base-services}.
+
+The value associated with @code{special-files-service-type} services must be
+a list of tuples where the first element is the ``special file'' and the
+second element is its target.  By default it is:
+
+@cindex @file{/bin/sh}
+@cindex @file{sh}, in @file{/bin}
+@example

+@end example
+
+@cindex @file{/usr/bin/env}
+@cindex @file{env}, in @file{/usr/bin}
+If you want to add, say, @code{/usr/bin/env} to your system, you can change

+default serial port used by the kernel Linux.
+
+For this, if there is a value for an option @code{agetty.tty} in the kernel

+and use that.
+
+If not and if there is a value for an option @code{console} with a tty in

+When set to @code{#t}, enable hardware (RTS/CTS) flow control.
+
+@item @code{no-issue?} (default: @code{#f})
+When set to @code{#t}, the contents of the @file{/etc/issue} file will not
+be displayed before presenting the login prompt.
+
+@item @code{init-string} (default: @code{#f})
+This accepts a string that will be sent to the tty or modem before sending
+anything else.  It can be used to initialize a modem.
+
+@item @code{no-clear?} (default: @code{#f})
+When set to @code{#t}, agetty will not clear the screen before showing the
+login prompt.
+
+@item @code{login-program} (default: (file-append shadow "/bin/login"))
+This must be either a gexp denoting the name of a log-in program, or unset,
+in which case the default value is the @command{login} from the Shadow tool
+suite.
+
+@item @code{local-line} (default: @code{#f})
+Control the CLOCAL line flag.  This accepts one of three symbols as
+arguments, @code{'auto}, @code{'always}, or @code{'never}. If @code{#f}, the
+default value chosen by agetty is @code{'auto}.
+
+@item @code{extract-baud?} (default: @code{#f})
+When set to @code{#t}, instruct agetty to try to extract the baud rate from
+the status messages produced by certain types of modems.
+
+@item @code{skip-login?} (default: @code{#f})
+When set to @code{#t}, do not prompt the user for a login name.  This can be
+used with @var{login-program} field to use non-standard login systems.
+
+@item @code{no-newline?} (default: @code{#f})
+When set to @code{#t}, do not print a newline before printing the
+@file{/etc/issue} file.
+
+@c Is this dangerous only when used with login-program, or always?
+@item @code{login-options} (default: @code{#f})
+This option accepts a string containing options that are passed to the login

+be parsed by the login program.
+
+@item @code{login-pause} (default: @code{#f})
+When set to @code{#t}, wait for any key before showing the login prompt.
+This can be used in conjunction with @var{auto-login} to save memory by
+lazily spawning shells.

+Use the Linux system call @code{vhangup} to do a virtual hangup of the
+specified terminal.
+
+@item @code{keep-baud?} (default: @code{#f})
+When set to @code{#t}, try to keep the existing baud rate.  The baud rates
+from @var{baud-rate} are used when agetty receives a @key{BREAK} character.
+
+@item @code{timeout} (default: @code{#f})
+When set to an integer value, terminate if no user name could be read within
+@var{timeout} seconds.
+
+@item @code{detect-case?} (default: @code{#f})
+When set to @code{#t}, turn on support for detecting an uppercase-only
+terminal.  This setting will detect a login name containing only uppercase
+letters as indicating an uppercase-only terminal and turn on some
+upper-to-lower case conversions.  Note that this will not support Unicode
+characters.
+
+@item @code{wait-cr?} (default: @code{#f})
+When set to @code{#t}, wait for the user or modem to send a carriage-return
+or linefeed character before displaying @file{/etc/issue} or login prompt.
+This is typically used with the @var{init-string} option.
+
+@item @code{no-hints?} (default: @code{#f})
+When set to @code{#t}, do not print hints about Num, Caps, and Scroll locks.
+
+@item @code{no-hostname?} (default: @code{#f})

+no hostname will be shown at all.
+
+@item @code{long-hostname?} (default: @code{#f})
+By default, the hostname is only printed until the first dot.  When this
+option is set to @code{#t}, the fully qualified hostname by

+@item @code{erase-characters} (default: @code{#f})
+This option accepts a string of additional characters that should be
+interpreted as backspace when the user types their login name.
+
+@item @code{kill-characters} (default: @code{#f})
+This option accepts a string that should be interpreted to mean "ignore all
+previous characters" (also called a "kill" character) when the types their
+login name.
+
+@item @code{chdir} (default: @code{#f})
+This option accepts, as a string, a directory path that will be changed to
+before login.
+
+@item @code{delay} (default: @code{#f})
+This options accepts, as an integer, the number of seconds to sleep before
+opening the tty and displaying the login prompt.
+
+@item @code{nice} (default: @code{#f})
+This option accepts, as an integer, the nice value with which to run the
+@command{login} program.
+
+@item @code{extra-options} (default: @code{'()})

+This is a list of two-element lists, each of which containing the subsystem
+name and a command (with optional arguments) to execute upon subsystem
+request.
+
+The command @command{internal-sftp} implements an in-process SFTP server.
+Alternately, one can specify the @command{sftp-server} command:

+
+This example allows ssh-clients to export the @code{COLORTERM} variable.  It
+is set by terminal emulators, which support colors.  You can use it in your
+shell's ressource file to enable colors for the prompt and commands if this

+@cindex authorized keys, SSH
+@cindex SSH authorized keys
+This is the list of authorized keys.  Each element of the list is a user

+@var{modules} must be a list of @dfn{module packages} loaded by the Xorg
+server---e.g., @code{xf86-video-vesa}, @code{xf86-input-keyboard}, and so
+on.  @var{fonts} must be a list of font directories to add to the server's
+@dfn{font path}.
+
+@var{drivers} must be either the empty list, in which case Xorg chooses a
+graphics driver automatically, or a list of driver names that will be tried
+in this order---e.g., @code{("modesetting" "vesa")}.
+
+Likewise, when @var{resolutions} is the empty list, Xorg chooses an

+
+@cindex printer support with CUPS
+The @code{(gnu services cups)} module provides a Guix service definition for
+the CUPS printing service.  To add printer support to a GuixSD system, add a
+@code{cups-service} to the operating system definition:
+
+@deffn {Scheme Variable} cups-service-type
+The service type for the CUPS print server.  Its value should be a valid
+CUPS configuration (see below).  To use the default settings, simply write:
+@example
+(service cups-service-type)
+@end example
+@end deffn
+
+The CUPS configuration controls the basic things about your CUPS
+installation: what interfaces it listens on, what to do if a print job
+fails, how much logging to do, and so on.  To actually add a printer, you
+have to visit the @url{http://localhost:631} URL, or use a tool such as
+GNOME's printer configuration services.  By default, configuring a CUPS
+service will generate a self-signed certificate if needed, for secure
+connections to the print server.
+
+Suppose you want to enable the Web interface of CUPS and also add support
+for Epson printers @i{via} the @code{escpr} package and for HP printers
+@i{via} the @code{hplip} package.  You can do that directly, like this (you
+need to use the @code{(gnu packages cups)} module):
+
+@example
+(service cups-service-type
+         (cups-configuration
+           (web-interface? #t)
+           (extensions
+             (list cups-filters escpr hplip))))
+@end example
+
+The available configuration parameters follow.  Each parameter definition is
+preceded by its type; for example, @samp{string-list foo} indicates that the
+@code{foo} parameter should be specified as a list of strings.  There is
+also a way to specify the configuration as a string, if you have an old
+@code{cupsd.conf} file that you want to port over from some other system;
+see the end for more details.
+
+@c The following documentation was initially generated by
+@c (generate-documentation) in (gnu services cups).  Manually maintained
+@c documentation is better, so we shouldn't hesitate to edit below as
+@c needed.  However if the change you want to make to this documentation
+@c can be done in an automated way, it's probably easier to change
+@c (generate-documentation) than to make it below and have to deal with
+@c the churn as CUPS updates.
+
+
+Available @code{cups-configuration} fields are:

+@deftypevr {@code{cups-configuration} parameter} package cups
+The CUPS package.

+
+At this point you're probably thinking ``oh dear, Guix manual, I like you
+but you can stop already with the configuration options''.  Indeed.
+However, one more point: it could be that you have an existing
+@code{cupsd.conf} that you want to use.  In that case, you can pass an
+@code{opaque-cups-configuration} as the configuration of a
+@code{cups-service-type}.
+
+Available @code{opaque-cups-configuration} fields are:
+
+@deftypevr {@code{opaque-cups-configuration} parameter} package cups
+The CUPS package.
+@end deftypevr
+
+@deftypevr {@code{opaque-cups-configuration} parameter} string cupsd.conf
+The contents of the @code{cupsd.conf}, as a string.
+@end deftypevr
+
+@deftypevr {@code{opaque-cups-configuration} parameter} string cups-files.conf
+The contents of the @code{cups-files.conf} file, as a string.
+@end deftypevr
+
+For example, if your @code{cupsd.conf} and @code{cups-files.conf} are in
+strings of the same name, you could instantiate a CUPS service like this:
+
+@example
+(service cups-service-type
+         (opaque-cups-configuration

+@node Desktop Services
+@subsubsection Desktop Services
+
+The @code{(gnu services desktop)} module provides services that are usually
+useful in the context of a ``desktop'' setup---that is, on a machine running
+a graphical display server, possibly with graphical user interfaces, etc.
+It also defines services that provide specific desktop environments like
+GNOME, XFCE or MATE.
+
+To simplify things, the module defines a variable containing the set of
+services that users typically expect on a machine with a graphical
+environment and networking:
+
+@defvr {Scheme Variable} %desktop-services
+This is a list of services that builds upon @var{%base-services} and adds or
+adjusts services for a typical ``desktop'' setup.
+
+In particular, it adds a graphical login manager (@pxref{X Window,
+@code{slim-service}}), screen lockers, a network management tool
+(@pxref{Networking Services, @code{network-manager-service-type}}), energy
+and color management services, the @code{elogind} login and seat manager,
+the Polkit privilege service, the GeoClue location service, the
+AccountsService daemon that allows authorized users change system passwords,
+an NTP client (@pxref{Networking Services}), the Avahi daemon, and has the
+name service switch service configured to be able to use @code{nss-mdns}
+(@pxref{Name Service Switch, mDNS}).
+@end defvr
+
+The @var{%desktop-services} variable can be used as the @code{services}
+field of an @code{operating-system} declaration (@pxref{Référence de système d'exploitation, @code{services}}).
+
+Additionally, the @code{gnome-desktop-service}, @code{xfce-desktop-service}
+and @code{mate-desktop-service} procedures can add GNOME, XFCE and/or MATE
+to a system.  To ``add GNOME'' means that system-level services like the
+backlight adjustment helpers and the power management utilities are added to
+the system, extending @code{polkit} and @code{dbus} appropriately, allowing
+GNOME to operate with elevated privileges on a limited number of
+special-purpose system interfaces.  Additionally, adding a service made by
+@code{gnome-desktop-service} adds the GNOME metapackage to the system
+profile.  Likewise, adding the XFCE service not only adds the @code{xfce}
+metapackage to the system profile, but it also gives the Thunar file manager
+the ability to open a ``root-mode'' file management window, if the user
+authenticates using the administrator's password via the standard polkit
+graphical interface.  To ``add MATE'' means that @code{polkit} and
+@code{dbus} are extended appropriately, allowing MATE to operate with
+elevated privileges on a limited number of special-purpose system
+interfaces.  Additionally, adding a service made by
+@code{mate-desktop-service} adds the MATE metapackage to the system profile.
+
+The desktop environments in Guix use the Xorg display server by default.  If
+you'd like to use the newer display server protocol called Wayland, you need
+to use the @code{sddm-service} instead of the @code{slim-service} for the
+graphical login manager.  You should then select the ``GNOME (Wayland)''
+session in SDDM.  Alternatively you can also try starting GNOME on Wayland
+manually from a TTY with the command ``XDG_SESSION_TYPE=wayland exec
+dbus-run-session gnome-session``.  Currently only GNOME has support for
+Wayland.
+
+@deffn {Scheme Procedure} gnome-desktop-service
+Return a service that adds the @code{gnome} package to the system profile,
+and extends polkit with the actions from @code{gnome-settings-daemon}.
+@end deffn
+
+@deffn {Scheme Procedure} xfce-desktop-service
+Return a service that adds the @code{xfce} package to the system profile,
+and extends polkit with the ability for @code{thunar} to manipulate the file
+system as root from within a user session, after the user has authenticated
+with the administrator's password.
+@end deffn
+
+@deffn {Scheme Procedure} mate-desktop-service
+Return a service that adds the @code{mate} package to the system profile,
+and extends polkit with the actions from @code{mate-settings-daemon}.
+@end deffn
+
+Because the GNOME, XFCE and MATE desktop services pull in so many packages,
+the default @code{%desktop-services} variable doesn't include either of them
+by default.  To add GNOME, XFCE or MATE, just @code{cons} them onto
+@code{%desktop-services} in the @code{services} field of your
+@code{operating-system}:
+
+@example
+(use-modules (gnu))
+(use-service-modules desktop)
+(operating-system
+  ...
+  ;; cons* adds items to the list given as its last argument.
+  (services (cons* (gnome-desktop-service)
+                   (xfce-desktop-service)
+                   %desktop-services))
+  ...)
+@end example
+
+These desktop environments will then be available as options in the
+graphical login window.
+
+The actual service definitions included in @code{%desktop-services} and
+provided by @code{(gnu services dbus)} and @code{(gnu services desktop)} are
+described below.
+
+@deffn {Scheme Procedure} dbus-service [#:dbus @var{dbus}] [#:services '()]
+Return a service that runs the ``system bus'', using @var{dbus}, with
+support for @var{services}.
+
+@uref{http://dbus.freedesktop.org/, D-Bus} is an inter-process communication
+facility.  Its system bus is used to allow system services to communicate
+and to be notified of system-wide events.
+
+@var{services} must be a list of packages that provide an
+@file{etc/dbus-1/system.d} directory containing additional D-Bus
+configuration and policy files.  For example, to allow avahi-daemon to use
+the system bus, @var{services} must be equal to @code{(list avahi)}.
+@end deffn
+
+@deffn {Scheme Procedure} elogind-service [#:config @var{config}]
+Return a service that runs the @code{elogind} login and seat management
+daemon.  @uref{https://github.com/elogind/elogind, Elogind} exposes a D-Bus
+interface that can be used to know which users are logged in, know what kind
+of sessions they have open, suspend the system, inhibit system suspend,
+reboot the system, and other tasks.
+
+Elogind handles most system-level power events for a computer, for example
+suspending the system when a lid is closed, or shutting it down when the
+power button is pressed.
+
+The @var{config} keyword argument specifies the configuration for elogind,
+and should be the result of an @code{(elogind-configuration (@var{parameter}

+@node Mail Services
+@subsubsection Mail Services
+
+@cindex mail
+@cindex email
+The @code{(gnu services mail)} module provides Guix service definitions for
+email services: IMAP, POP3, and LMTP servers, as well as mail transport
+agents (MTAs).  Lots of acronyms! These services are detailed in the
+subsections below.
+
+@subsubheading Dovecot Service
+
+@deffn {Scheme Procedure} dovecot-service [#:config (dovecot-configuration)]
+Return a service that runs the Dovecot IMAP/POP3/LMTP mail server.
+@end deffn
+
+By default, Dovecot does not need much configuration; the default
+configuration object created by @code{(dovecot-configuration)} will suffice
+if your mail is delivered to @code{~/Maildir}.  A self-signed certificate
+will be generated for TLS-protected connections, though Dovecot will also
+listen on cleartext ports by default.  There are a number of options,
+though, which mail administrators might need to change, and as is the case
+with other services, Guix allows the system administrator to specify these
+parameters via a uniform Scheme interface.
+
+For example, to specify that mail is located at @code{maildir~/.mail}, one
+would instantiate the Dovecot service like this:
+
+@example

+The available configuration parameters follow.  Each parameter definition is
+preceded by its type; for example, @samp{string-list foo} indicates that the
+@code{foo} parameter should be specified as a list of strings.  There is

+@code{dovecot.conf} file that you want to port over from some other system;
+see the end for more details.

+@c The following documentation was initially generated by

+@c documentation is better, so we shouldn't hesitate to edit below as
+@c needed.  However if the change you want to make to this documentation
+@c can be done in an automated way, it's probably easier to change
+@c (generate-documentation) than to make it below and have to deal with
+@c the churn as dovecot updates.

+Show more verbose process titles (in ps).  Currently shows user name and IP
+address.  Useful for seeing who is actually using the IMAP processes
+(e.g. shared mailboxes or if the same uid is used for multiple accounts).
+Defaults to @samp{#f}.
+@end deftypevr
+
+@deftypevr {@code{dovecot-configuration} parameter} boolean shutdown-clients?
+Should all processes be killed when Dovecot master process shuts down.
+Setting this to @code{#f} means that Dovecot can be upgraded without forcing
+existing client connections to close (although that could also be a problem
+if the upgrade is e.g. due to a security fix).  Defaults to @samp{#t}.
+@end deftypevr
+
+@deftypevr {@code{dovecot-configuration} parameter} non-negative-integer doveadm-worker-count
+If non-zero, run mail commands via this many connections to doveadm server,

+Disable LOGIN command and all other plaintext authentications unless SSL/TLS
+is used (LOGINDISABLED capability).  Note that if the remote IP matches the

+@end deftypevr
+
+@deftypevr {@code{dovecot-configuration} parameter} non-negative-integer auth-cache-size
+Authentication cache size (e.g. @samp{#e10e6}).  0 means it's disabled.

+caching to be used.  Defaults to @samp{0}.
+@end deftypevr
+
+@deftypevr {@code{dovecot-configuration} parameter} string auth-cache-ttl
+Time to live for cached data.  After TTL expires the cached record is no
+longer used, *except* if the main database lookup returns internal failure.
+We also try to handle password changes automatically: If user's previous
+authentication was successful, but this one wasn't, the cache isn't used.
+For now this works only with plaintext authentication.  Defaults to @samp{"1
+hour"}.
+@end deftypevr
+
+@deftypevr {@code{dovecot-configuration} parameter} string auth-cache-negative-ttl

+Defaults to @samp{""}.
+@end deftypevr
+
+@deftypevr {@code{dovecot-configuration} parameter} string auth-username-chars
+List of allowed characters in username.  If the user-given username contains
+a character not listed in here, the login automatically fails.  This is just
+an extra check to make sure user can't exploit any potential quote escaping
+vulnerabilities with SQL/LDAP databases.  If you want to allow all
+characters, set this value to empty.  Defaults to
+@samp{"abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ01234567890.-_@@"}.
+@end deftypevr
+
+@deftypevr {@code{dovecot-configuration} parameter} string auth-username-translation
+Username character translations before it's looked up from databases.  The
+value contains series of from -> to characters.  For example @samp{#@@/@@}

+Defaults to @samp{""}.
+@end deftypevr
+
+@deftypevr {@code{dovecot-configuration} parameter} string auth-username-format
+Username formatting before it's looked up from databases.  You can use the
+standard variables here, e.g. %Lu would lowercase the username, %n would
+drop away the domain if it was given, or @samp{%n-AT-%d} would change the
+@samp{@@} into @samp{-AT-}.  This translation is done after
+@samp{auth-username-translation} changes.  Defaults to @samp{"%Lu"}.
+@end deftypevr
+
+@deftypevr {@code{dovecot-configuration} parameter} string auth-master-user-separator
+If you want to allow master users to log in by specifying the master
+username within the normal username string (i.e. not using SASL mechanism's
+support for it), you can specify the separator character here.  The format
+is then <username><separator><master username>.  UW-IMAP uses @samp{*} as
+the separator, so that could be a good choice.  Defaults to @samp{""}.
+@end deftypevr
+
+@deftypevr {@code{dovecot-configuration} parameter} string auth-anonymous-username
+Username to use for users logging in with ANONYMOUS SASL mechanism.
+Defaults to @samp{"anonymous"}.

+
+@deftypevr {@code{dovecot-configuration} parameter} string auth-gssapi-hostname
+Host name to use in GSSAPI principal names.  The default is to use the name

+
+@deftypevr {@code{dovecot-configuration} parameter} string auth-krb5-keytab
+Kerberos keytab to use for the GSSAPI mechanism.  Will use the system

+change the auth service to run as root to be able to read this file.
+Defaults to @samp{""}.
+@end deftypevr
+
+@deftypevr {@code{dovecot-configuration} parameter} boolean auth-use-winbind?
+Do NTLM and GSS-SPNEGO authentication using Samba's winbind daemon and

+@deftypevr {@code{dovecot-configuration} parameter} string deliver-log-format
+Format to use for logging mail deliveries.  You can use variables:
+@table @code
+@item %$
+Delivery status message (e.g. @samp{saved to INBOX})
+@item %m
+Message-ID
+@item %s
+Subject
+@item %f
+From address
+@item %p
+Physical size
+@item %w
+Virtual size.
+@end table
+Defaults to @samp{"msgid=%m: %$"}.
+@end deftypevr
+
+@deftypevr {@code{dovecot-configuration} parameter} string mail-location
+Location for users' mailboxes.  The default is empty, which means that
+Dovecot tries to find the mailboxes automatically.  This won't work if the
+user doesn't yet have any mail, so you should explicitly tell Dovecot the
+full location.
+
+If you're using mbox, giving a path to the INBOX file (e.g. /var/mail/%u)
+isn't enough.  You'll also need to tell Dovecot where the other mailboxes
+are kept.  This is called the "root mail directory", and it must be the
+first path given in the @samp{mail-location} setting.
+
+There are a few special variables you can use, eg.:
+
+@table @samp
+@item %u
+username
+@item %n
+user part in user@@domain, same as %u if there's no domain
+@item %d
+domain part in user@@domain, empty if there's no domain
+@item %h
+home director
+@end table
+
+See doc/wiki/Variables.txt for full list.  Some examples:
+@table @samp
+@item maildir:~/Maildir
+@item mbox:~/mail:INBOX=/var/mail/%u
+@item mbox:/var/mail/%d/%1n/%n:INDEX=/var/indexes/%d/%1n/%
+@end table
+Defaults to @samp{""}.
+@end deftypevr
+
+@deftypevr {@code{dovecot-configuration} parameter} string mail-uid
+System user and group used to access mails.  If you use multiple, userdb can
+override these by returning uid or gid fields.  You can use either numbers
+or names.  <doc/wiki/UserIds.txt>.  Defaults to @samp{""}.
+@end deftypevr
+
+@deftypevr {@code{dovecot-configuration} parameter} string mail-gid
+
+Defaults to @samp{""}.
+@end deftypevr
+
+@deftypevr {@code{dovecot-configuration} parameter} string mail-privileged-group
+Group to enable temporarily for privileged operations.  Currently this is
+used only with INBOX when either its initial creation or dotlocking fails.
+Typically this is set to "mail" to give access to /var/mail.  Defaults to
+@samp{""}.
+@end deftypevr
+
+@deftypevr {@code{dovecot-configuration} parameter} string mail-access-groups
+Grant access to these supplementary groups for mail processes.  Typically
+these are used to set up access to shared mailboxes.  Note that it may be
+dangerous to set these if users can create symlinks (e.g. if "mail" group is
+set here, ln -s /var/mail ~/mail/var could allow a user to delete others'
+mailboxes, or ln -s /secret/shared/box ~/mail/mybox would allow reading
+it).  Defaults to @samp{""}.
+@end deftypevr
+
+@deftypevr {@code{dovecot-configuration} parameter} boolean mail-full-filesystem-access?
+Allow full file system access to clients.  There's no access checks other
+than what the operating system does for the active UID/GID.  It works with
+both maildir and mboxes, allowing you to prefix mailboxes names with
+e.g. /path/ or ~user/.  Defaults to @samp{#f}.
+@end deftypevr
+
+@deftypevr {@code{dovecot-configuration} parameter} boolean mmap-disable?
+Don't use mmap() at all.  This is required if you store indexes to shared
+file systems (NFS or clustered file system).  Defaults to @samp{#f}.
+@end deftypevr
+
+@deftypevr {@code{dovecot-configuration} parameter} boolean dotlock-use-excl?
+Rely on @samp{O_EXCL} to work when creating dotlock files.  NFS supports
+@samp{O_EXCL} since version 3, so this should be safe to use nowadays by
+default.  Defaults to @samp{#t}.
+@end deftypevr
+
+@deftypevr {@code{dovecot-configuration} parameter} string mail-fsync
+When to use fsync() or fdatasync() calls:
+@table @code
+@item optimized
+Whenever necessary to avoid losing important data
+@item always
+Useful with e.g. NFS when write()s are delayed
+@item never
+Never use it (best performance, but crashes can lose data).
+@end table
+Defaults to @samp{"optimized"}.
+@end deftypevr
+
+@deftypevr {@code{dovecot-configuration} parameter} boolean mail-nfs-storage?
+Mail storage exists in NFS.  Set this to yes to make Dovecot flush NFS
+caches whenever needed.  If you're using only a single mail server this
+isn't needed.  Defaults to @samp{#f}.
+@end deftypevr
+
+@deftypevr {@code{dovecot-configuration} parameter} boolean mail-nfs-index?
+Mail index files also exist in NFS.  Setting this to yes requires
+@samp{mmap-disable? #t} and @samp{fsync-disable? #f}.  Defaults to
+@samp{#f}.
+@end deftypevr
+
+@deftypevr {@code{dovecot-configuration} parameter} string lock-method
+Locking method for index files.  Alternatives are fcntl, flock and dotlock.
+Dotlocking uses some tricks which may create more disk I/O than other
+locking methods.  NFS users: flock doesn't work, remember to change
+@samp{mmap-disable}.  Defaults to @samp{"fcntl"}.
+@end deftypevr
+
+@deftypevr {@code{dovecot-configuration} parameter} file-name mail-temp-dir
+Directory in which LDA/LMTP temporarily stores incoming mails >128 kB.
+Defaults to @samp{"/tmp"}.
+@end deftypevr
+
+@deftypevr {@code{dovecot-configuration} parameter} non-negative-integer first-valid-uid
+Valid UID range for users.  This is mostly to make sure that users can't log
+in as daemons or other system users.  Note that denying root logins is
+hardcoded to dovecot binary and can't be done even if @samp{first-valid-uid}
+is set to 0.  Defaults to @samp{500}.
+@end deftypevr
+
+@deftypevr {@code{dovecot-configuration} parameter} non-negative-integer last-valid-uid
+
+Defaults to @samp{0}.
+@end deftypevr
+
+@deftypevr {@code{dovecot-configuration} parameter} non-negative-integer first-valid-gid
+Valid GID range for users.  Users having non-valid GID as primary group ID
+aren't allowed to log in.  If user belongs to supplementary groups with
+non-valid GIDs, those groups are not set.  Defaults to @samp{1}.
+@end deftypevr
+
+@deftypevr {@code{dovecot-configuration} parameter} non-negative-integer last-valid-gid
+
+Defaults to @samp{0}.
+@end deftypevr
+
+@deftypevr {@code{dovecot-configuration} parameter} non-negative-integer mail-max-keyword-length
+Maximum allowed length for mail keyword name.  It's only forced when trying
+to create new keywords.  Defaults to @samp{50}.
+@end deftypevr
+
+@deftypevr {@code{dovecot-configuration} parameter} colon-separated-file-name-list valid-chroot-dirs
+List of directories under which chrooting is allowed for mail processes
+(i.e. /var/mail will allow chrooting to /var/mail/foo/bar too).  This
+setting doesn't affect @samp{login-chroot} @samp{mail-chroot} or auth chroot
+settings.  If this setting is empty, "/./" in home dirs are ignored.
+WARNING: Never add directories here which local users can modify, that may
+lead to root exploit.  Usually this should be done only if you don't allow
+shell access for users.  <doc/wiki/Chrooting.txt>.  Defaults to @samp{()}.
+@end deftypevr
+
+@deftypevr {@code{dovecot-configuration} parameter} string mail-chroot
+Default chroot directory for mail processes.  This can be overridden for
+specific users in user database by giving /./ in user's home directory
+(e.g. /home/./user chroots into /home).  Note that usually there is no real
+need to do chrooting, Dovecot doesn't allow users to access files outside
+their mail directory anyway.  If your home directories are prefixed with the
+chroot directory, append "/." to @samp{mail-chroot}.
+<doc/wiki/Chrooting.txt>.  Defaults to @samp{""}.
+@end deftypevr
+
+@deftypevr {@code{dovecot-configuration} parameter} file-name auth-socket-path
+UNIX socket path to master authentication server to find users.  This is
+used by imap (for shared users) and lda.  Defaults to
+@samp{"/var/run/dovecot/auth-userdb"}.
+@end deftypevr
+
+@deftypevr {@code{dovecot-configuration} parameter} file-name mail-plugin-dir
+Directory where to look up mail plugins.  Defaults to
+@samp{"/usr/lib/dovecot"}.
+@end deftypevr
+
+@deftypevr {@code{dovecot-configuration} parameter} space-separated-string-list mail-plugins
+List of plugins to load for all services.  Plugins specific to IMAP, LDA,
+etc. are added to this list in their own .conf files.  Defaults to
+@samp{()}.
+@end deftypevr
+
+@deftypevr {@code{dovecot-configuration} parameter} non-negative-integer mail-cache-min-mail-count
+The minimum number of mails in a mailbox before updates are done to cache
+file.  This allows optimizing Dovecot's behavior to do less disk writes at
+the cost of more disk reads.  Defaults to @samp{0}.
+@end deftypevr
+
+@deftypevr {@code{dovecot-configuration} parameter} string mailbox-idle-check-interval
+When IDLE command is running, mailbox is checked once in a while to see if
+there are any new mails or other changes.  This setting defines the minimum
+time to wait between those checks.  Dovecot can also use dnotify, inotify
+and kqueue to find out immediately when changes occur.  Defaults to
+@samp{"30 secs"}.
+@end deftypevr
+
+@deftypevr {@code{dovecot-configuration} parameter} boolean mail-save-crlf?
+Save mails with CR+LF instead of plain LF.  This makes sending those mails
+take less CPU, especially with sendfile() syscall with Linux and FreeBSD.
+But it also creates a bit more disk I/O which may just make it slower.  Also
+note that if other software reads the mboxes/maildirs, they may handle the
+extra CRs wrong and cause problems.  Defaults to @samp{#f}.
+@end deftypevr
+
+@deftypevr {@code{dovecot-configuration} parameter} boolean maildir-stat-dirs?
+By default LIST command returns all entries in maildir beginning with a
+dot.  Enabling this option makes Dovecot return only entries which are
+directories.  This is done by stat()ing each entry, so it causes more disk
+I/O.  (For systems setting struct @samp{dirent->d_type} this check is free
+and it's done always regardless of this setting).  Defaults to @samp{#f}.
+@end deftypevr
+
+@deftypevr {@code{dovecot-configuration} parameter} boolean maildir-copy-with-hardlinks?
+When copying a message, do it with hard links whenever possible.  This makes
+the performance much better, and it's unlikely to have any side effects.
+Defaults to @samp{#t}.
+@end deftypevr
+
+@deftypevr {@code{dovecot-configuration} parameter} boolean maildir-very-dirty-syncs?
+Assume Dovecot is the only MUA accessing Maildir: Scan cur/ directory only
+when its mtime changes unexpectedly or when we can't find the mail
+otherwise.  Defaults to @samp{#f}.
+@end deftypevr
+
+@deftypevr {@code{dovecot-configuration} parameter} space-separated-string-list mbox-read-locks
+Which locking methods to use for locking mbox.  There are four available:
+
+@table @code
+@item dotlock
+Create <mailbox>.lock file.  This is the oldest and most NFS-safe solution.
+If you want to use /var/mail/ like directory, the users will need write
+access to that directory.
+@item dotlock-try
+Same as dotlock, but if it fails because of permissions or because there
+isn't enough disk space, just skip it.
+@item fcntl
+Use this if possible.  Works with NFS too if lockd is used.
+@item flock
+May not exist in all systems.  Doesn't work with NFS.
+@item lockf
+May not exist in all systems.  Doesn't work with NFS.
+@end table
+
+You can use multiple locking methods; if you do the order they're declared
+in is important to avoid deadlocks if other MTAs/MUAs are using multiple
+locking methods as well.  Some operating systems don't allow using some of
+them simultaneously.
+@end deftypevr
+
+@deftypevr {@code{dovecot-configuration} parameter} space-separated-string-list mbox-write-locks
+
+@end deftypevr
+
+@deftypevr {@code{dovecot-configuration} parameter} string mbox-lock-timeout
+Maximum time to wait for lock (all of them) before aborting.  Defaults to
+@samp{"5 mins"}.
+@end deftypevr
+
+@deftypevr {@code{dovecot-configuration} parameter} string mbox-dotlock-change-timeout
+If dotlock exists but the mailbox isn't modified in any way, override the
+lock file after this much time.  Defaults to @samp{"2 mins"}.
+@end deftypevr
+
+@deftypevr {@code{dovecot-configuration} parameter} boolean mbox-dirty-syncs?
+When mbox changes unexpectedly we have to fully read it to find out what
+changed.  If the mbox is large this can take a long time.  Since the change
+is usually just a newly appended mail, it'd be faster to simply read the new
+mails.  If this setting is enabled, Dovecot does this but still safely
+fallbacks to re-reading the whole mbox file whenever something in mbox isn't
+how it's expected to be.  The only real downside to this setting is that if
+some other MUA changes message flags, Dovecot doesn't notice it
+immediately.  Note that a full sync is done with SELECT, EXAMINE, EXPUNGE
+and CHECK commands.  Defaults to @samp{#t}.
+@end deftypevr
+
+@deftypevr {@code{dovecot-configuration} parameter} boolean mbox-very-dirty-syncs?
+Like @samp{mbox-dirty-syncs}, but don't do full syncs even with SELECT,
+EXAMINE, EXPUNGE or CHECK commands.  If this is set, @samp{mbox-dirty-syncs}
+is ignored.  Defaults to @samp{#f}.
+@end deftypevr
+
+@deftypevr {@code{dovecot-configuration} parameter} boolean mbox-lazy-writes?
+Delay writing mbox headers until doing a full write sync (EXPUNGE and CHECK
+commands and when closing the mailbox).  This is especially useful for POP3
+where clients often delete all mails.  The downside is that our changes
+aren't immediately visible to other MUAs.  Defaults to @samp{#t}.
+@end deftypevr
+
+@deftypevr {@code{dovecot-configuration} parameter} non-negative-integer mbox-min-index-size
+If mbox size is smaller than this (e.g. 100k), don't write index files.  If
+an index file already exists it's still read, just not updated.  Defaults to
+@samp{0}.
+@end deftypevr
+
+@deftypevr {@code{dovecot-configuration} parameter} non-negative-integer mdbox-rotate-size
+Maximum dbox file size until it's rotated.  Defaults to @samp{10000000}.
+@end deftypevr
+
+@deftypevr {@code{dovecot-configuration} parameter} string mdbox-rotate-interval
+Maximum dbox file age until it's rotated.  Typically in days.  Day begins
+from midnight, so 1d = today, 2d = yesterday, etc.  0 = check disabled.
+Defaults to @samp{"1d"}.
+@end deftypevr
+
+@deftypevr {@code{dovecot-configuration} parameter} boolean mdbox-preallocate-space?
+When creating new mdbox files, immediately preallocate their size to
+@samp{mdbox-rotate-size}.  This setting currently works only in Linux with
+some file systems (ext4, xfs).  Defaults to @samp{#f}.
+@end deftypevr
+
+@deftypevr {@code{dovecot-configuration} parameter} string mail-attachment-dir
+sdbox and mdbox support saving mail attachments to external files, which
+also allows single instance storage for them.  Other backends don't support
+this for now.
+
+WARNING: This feature hasn't been tested much yet.  Use at your own risk.
+
+Directory root where to store mail attachments.  Disabled, if empty.
+Defaults to @samp{""}.
+@end deftypevr
+
+@deftypevr {@code{dovecot-configuration} parameter} non-negative-integer mail-attachment-min-size
+Attachments smaller than this aren't saved externally.  It's also possible
+to write a plugin to disable saving specific attachments externally.
+Defaults to @samp{128000}.
+@end deftypevr
+
+@deftypevr {@code{dovecot-configuration} parameter} string mail-attachment-fs
+File system backend to use for saving attachments:
+@table @code
+@item posix
+No SiS done by Dovecot (but this might help FS's own deduplication)
+@item sis posix
+SiS with immediate byte-by-byte comparison during saving
+@item sis-queue posix
+SiS with delayed comparison and deduplication.
+@end table
+Defaults to @samp{"sis posix"}.
+@end deftypevr
+
+@deftypevr {@code{dovecot-configuration} parameter} string mail-attachment-hash
+Hash format to use in attachment filenames.  You can add any text and
+variables: @code{%@{md4@}}, @code{%@{md5@}}, @code{%@{sha1@}},
+@code{%@{sha256@}}, @code{%@{sha512@}}, @code{%@{size@}}.  Variables can be
+truncated, e.g. @code{%@{sha256:80@}} returns only first 80 bits.  Defaults
+to @samp{"%@{sha1@}"}.

+@end deftypevr
+
+@deftypevr {@code{dovecot-configuration} parameter} string default-login-user
+Login user is internally used by login processes.  This is the most

+all.  Defaults to @samp{"dovenull"}.
+@end deftypevr
+
+@deftypevr {@code{dovecot-configuration} parameter} string default-internal-user
+Internal user is used by unprivileged processes.  It should be separate from

+@end deftypevr
+
+@deftypevr {@code{dovecot-configuration} parameter} string ssl-key
+PEM encoded SSL/TLS private key.  The key is opened before dropping root

+@end deftypevr
+
+@deftypevr {@code{dovecot-configuration} parameter} string ssl-key-password
+If key file is password protected, give the password here.  Alternatively

+
+@deftypevr {@code{dovecot-configuration} parameter} string ssl-ca
+PEM encoded trusted certificate authority.  Set this only if you intend to

+
+@item tb-extra-mailbox-sep
+Thunderbird gets somehow confused with LAYOUT=fs (mbox and dbox) and adds
+extra @samp{/} suffixes to mailbox names.  This option causes Dovecot to
+ignore the extra @samp{/} instead of treating it as invalid mailbox name.
+
+@item tb-lsub-flags
+Show \Noselect flags for LSUB replies with LAYOUT=fs (e.g. mbox).  This
+makes Thunderbird realize they aren't selectable and show them greyed out,
+instead of only later giving "not selectable" popup error.

+
+
+Whew! Lots of configuration options.  The nice thing about it though is that
+GuixSD has a complete interface to Dovecot's configuration language.  This
+allows not only a nice way to declare configurations, but also offers
+reflective capabilities as well: users can write code to inspect and
+transform configurations from within Scheme.
+
+However, it could be that you just want to get a @code{dovecot.conf} up and
+running.  In that case, you can pass an @code{opaque-dovecot-configuration}
+as the @code{#:config} parameter to @code{dovecot-service}.  As its name
+indicates, an opaque configuration does not have easy reflective
+capabilities.
+
+Available @code{opaque-dovecot-configuration} fields are:
+
+@deftypevr {@code{opaque-dovecot-configuration} parameter} package dovecot
+The dovecot package.
+@end deftypevr
+
+@deftypevr {@code{opaque-dovecot-configuration} parameter} string string
+The contents of the @code{dovecot.conf}, as a string.
+@end deftypevr
+
+For example, if your @code{dovecot.conf} is just the empty string, you could
+instantiate a dovecot service like this:
+
+@example
+(dovecot-service #:config
+                 (opaque-dovecot-configuration
+                  (string "")))

+
+@deffn {Scheme Variable} mail-aliases-service-type
+This is the type of the service which provides @code{/etc/aliases},

+
+The configuration for a @code{mail-aliases-service-type} service is an
+association list denoting how to deliver mail that comes to this
+system. Each entry is of the form @code{(alias addresses ...)}, with
+@code{alias} specifying the local alias and @code{addresses} specifying
+where to deliver this user's mail.
+
+The aliases aren't required to exist as users on the local system. In the
+above example, there doesn't need to be a @code{postmaster} entry in the
+@code{operating-system}'s @code{user-accounts} in order to deliver the
+@code{postmaster} mail to @code{bob} (which subsequently would deliver mail

+The @code{(gnu services messaging)} module provides Guix service definitions
+for messaging services: currently only Prosody is supported.
+
+@subsubheading Prosody Service
+
+@deffn {Scheme Variable} prosody-service-type
+This is the type for the @uref{https://prosody.im, Prosody XMPP
+communication server}.  Its value must be a @code{prosody-configuration}
+record as in this example:
+
+@example
+(service prosody-service-type
+         (prosody-configuration
+          (modules-enabled (cons "groups" "mam" %default-modules-enabled))
+          (int-components

+           (list
+            (virtualhost-configuration
+             (domain "example.net"))))))
+@end example
+
+See below for details about @code{prosody-configuration}.
+
+@end deffn
+
+By default, Prosody does not need much configuration.  Only one
+@code{virtualhosts} field is needed: it specifies the domain you wish
+Prosody to serve.
+
+You can perform various sanity checks on the generated configuration with
+the @code{prosodyctl check} command.
+
+Prosodyctl will also help you to import certificates from the
+@code{letsencrypt} directory so that the @code{prosody} user can access
+them.  See @url{https://prosody.im/doc/letsencrypt}.
+
+@example
+prosodyctl --root cert import /etc/letsencrypt/live
+@end example
+
+The available configuration parameters follow.  Each parameter definition is
+preceded by its type; for example, @samp{string-list foo} indicates that the
+@code{foo} parameter should be specified as a list of strings.  Types
+starting with @code{maybe-} denote parameters that won't show up in
+@code{prosody.cfg.lua} when their value is @code{'disabled}.
+
+There is also a way to specify the configuration as a string, if you have an
+old @code{prosody.cfg.lua} file that you want to port over from some other
+system; see the end for more details.
+
+The @code{file-object} type designates either a file-like object
+(@pxref{G-Expressions, file-like objects}) or a file name.
+
+@c The following documentation was initially generated by
+@c (generate-documentation) in (gnu services messaging).  Manually maintained
+@c documentation is better, so we shouldn't hesitate to edit below as
+@c needed.  However if the change you want to make to this documentation
+@c can be done in an automated way, it's probably easier to change

+@cindex VoIP server
+This section describes how to set up and run a Murmur server.  Murmur is the
+server of the @uref{https://mumble.info, Mumble} voice-over-IP (VoIP) suite.
+
+@deftp {Data Type} murmur-configuration
+The service type for the Murmur server.  An example configuration can look
+like this:
+
+@example
+(service murmur-service-type
+         (murmur-configuration
+          (welcome-text
+            "Welcome to this Mumble server running on GuixSD!")

+          (ssl-key "/etc/letsencrypt/live/mumble.example.com/privkey.pem")))
+@end example
+
+After reconfiguring your system, you can manually set the murmur
+@code{SuperUser} password with the command that is printed during the
+activation phase.
+
+It is recommended to register a normal Mumble user account and grant it
+admin or moderator rights.  You can use the @code{mumble} client to login as
+new normal user, register yourself, and log out.  For the next step login
+with the name @code{SuperUser} use the @code{SuperUser} password that you
+set previously, and grant your newly registered mumble user administrator or
+moderator rights and create some channels.
+

+@end example
+
+In addition to adding server blocks to the service configuration directly,

+
+At startup, @command{nginx} has not yet read its configuration file, so it
+uses a default file to log error messages.  If it fails to load its
+configuration file, that is where error messages are logged.  After the
+configuration file is loaded, the default error log file changes as per
+configuration.  In our case, startup error messages can be found in
+@file{/var/run/nginx/logs/error.log}, and after configuration in
+@file{/var/log/nginx/error.log}.  The second location can be changed with
+the @var{log-directory} configuration option.
+
+@deffn {Data Type} nginx-configuration
+This data type represents the configuration for NGinx. Some configuration
+can be done through this and the other provided record types, or

+
+@table @asis
+@item @code{nginx} (default: @code{nginx})
+The nginx package to use.
+

+The directory to which NGinx will write log files.
+
+@item @code{run-directory} (default: @code{"/var/run/nginx"})
+The directory in which NGinx will create a pid file, and write temporary
+files.
+
+@item @code{server-blocks} (default: @code{'()})
+A list of @dfn{server blocks} to create in the generated configuration file,
+the elements should be of type @code{<nginx-server-configuration>}.
+
+The following example would setup NGinx to serve @code{www.example.com} from
+the @code{/srv/http/www.example.com} directory, without using HTTPS.
+@example

+
+Configuring upstreams through the @code{upstream-blocks} can be useful when
+combined with @code{locations} in the @code{<nginx-server-configuration>}

+@end example
+
+@item @code{file} (default: @code{#f})
+If a configuration @var{file} is provided, this will be used, rather than
+generating a configuration file from the provided @code{log-directory},
+@code{run-directory}, @code{server-blocks} and @code{upstream-blocks}.  For

+
+This can be useful if you have an existing configuration file, or it's not

+@cindex fastcgi

+FastCGI is an interface between the front-end and the back-end of a web

+generally just talk HTTP between the front-end and the back-end.  However
+there are a number of back-end services such as PHP or the optimized HTTP
+Git repository access that use FastCGI, so we have support for it in Guix.
+
+To use FastCGI, you configure the front-end web server (e.g., nginx) to
+dispatch some subset of its requests to the fastcgi backend, which listens
+on a local TCP or UNIX socket.  There is an intermediary @code{fcgiwrap}
+program that sits between the actual backend process and the web server.
+The front-end indicates which backend program to run, passing that
+information to the @code{fcgiwrap} process.
+
+@defvr {Scheme Variable} fcgiwrap-service-type

+The fcgiwrap package to use.
+
+@item @code{socket} (default: @code{tcp:127.0.0.1:9000})
+The socket on which the @code{fcgiwrap} process should listen, as a string.
+Valid @var{socket} values include @code{unix:@var{/path/to/unix/socket}},
+@code{tcp:@var{dot.ted.qu.ad}:@var{port}} and
+@code{tcp6:[@var{ipv6_addr}]:port}.
+
+@item @code{user} (default: @code{fcgiwrap})
+@itemx @code{group} (default: @code{fcgiwrap})
+The user and group names, as strings, under which to run the @code{fcgiwrap}
+process.  The @code{fastcgi} service will ensure that if the user asks for
+the specific user or group names @code{fcgiwrap} that the corresponding user
+and/or group is present on the system.
+
+It is possible to configure a FastCGI-backed web service to pass HTTP
+authentication information from the front-end to the back-end, and to allow
+@code{fcgiwrap} to run the back-end process as a corresponding local user.
+To enable this capability on the back-end., run @code{fcgiwrap} as the
+@code{root} user and group.  Note that this capability also has to be
+configured on the front-end as well.

+@subsubsection Certificate Services

+@cindex Web
+@cindex HTTP, HTTPS
+@cindex Let's Encrypt
+@cindex TLS certificates
+The @code{(gnu services certbot)} module provides a service to automatically
+obtain a valid TLS certificate from the Let's Encrypt certificate
+authority.  These certificates can then be used to serve content securely
+over HTTPS or other TLS-based protocols, with the knowledge that the client
+will be able to verify the server's authenticity.
+
+@url{https://letsencrypt.org/, Let's Encrypt} provides the @code{certbot}
+tool to automate the certification process.  This tool first securely
+generates a key on the server.  It then makes a request to the Let's Encrypt
+certificate authority (CA) to sign the key.  The CA checks that the request
+originates from the host in question by using a challenge-response protocol,
+requiring the server to provide its response over HTTP.  If that protocol
+completes successfully, the CA signs the key, resulting in a certificate.
+That certificate is valid for a limited period of time, and therefore to
+continue to provide TLS services, the server needs to periodically ask the
+CA to renew its signature.
+
+The certbot service automates this process: the initial key generation, the
+initial certification request to the Let's Encrypt service, the web server
+challenge/response integration, writing the certificate to disk, the
+automated periodic renewals, and the deployment tasks associated with the
+renewal (e.g. reloading services, copying keys with different permissions).
+
+Certbot is run twice a day, at a random minute within the hour.  It won't do
+anything until your certificates are due for renewal or revoked, but running
+it regularly would give your service a chance of staying online in case a
+Let's Encrypt-initiated revocation happened for some reason.
+
+By using this service, you agree to the ACME Subscriber Agreement, which can
+be found there: @url{https://acme-v01.api.letsencrypt.org/directory}.

+@node DNS Services
+@subsubsection DNS Services
+@cindex DNS (domain name system)
+@cindex domain name system (DNS)
+
+The @code{(gnu services dns)} module provides services related to the
+@dfn{domain name system} (DNS).  It provides a server service for hosting an
+@emph{authoritative} DNS server for multiple zones, slave or master.  This
+service uses @uref{https://www.knot-dns.cz/, Knot DNS}.
+
+An example configuration of an authoritative server for two zones, one
+master and one slave, is:
+
+@lisp
+(define-zone-entries example.org.zone
+;; Name TTL Class Type Data
+  ("@@"  ""  "IN"  "A"  "127.0.0.1")
+  ("@@"  ""  "IN"  "NS" "ns")

+
+(define master-zone
+  (knot-zone-configuration
+    (domain "example.org")
+    (zone (zone-file
+            (origin "example.org")
+            (entries example.org.zone)))))
+
+(define slave-zone
+  (knot-zone-configuration
+    (domain "plop.org")

+                   ;; ...
+                   %base-services)))
+@end lisp
+
+@deffn {Scheme Variable} knot-service-type
+This is the type for the Knot DNS server.
+
+Knot DNS is an authoritative DNS server, meaning that it can serve multiple
+zones, that is to say domain names you would buy from a registrar.  This
+server is not a resolver, meaning that it can only resolve names for which
+it is authoritative.  This server can be configured to serve zones as a
+master server or a slave server as a per-zone basis.  Slave zones will get
+their data from masters, and will serve it as an authoritative server.  From
+the point of view of a resolver, there is no difference between master and
+slave.
+
+The following data types are used to configure the Knot DNS server:
+@end deffn
+
+@deftp {Data Type} knot-key-configuration
+Data type representing a key.  This type has the following parameters:
+
+@table @asis
+@item @code{id} (default: @code{""})
+An identifier for other configuration fields to refer to this key. IDs must
+be unique and must not be empty.
+
+@item @code{algorithm} (default: @code{#f})
+The algorithm to use.  Choose between @code{#f}, @code{'hmac-md5},
+@code{'hmac-sha1}, @code{'hmac-sha224}, @code{'hmac-sha256},
+@code{'hmac-sha384} and @code{'hmac-sha512}.
+
+@item @code{secret} (default: @code{""})
+The secret key itself.
+
+@end table
+@end deftp
+
+@deftp {Data Type} knot-acl-configuration
+Data type representing an Access Control List (ACL) configuration.  This
+type has the following parameters:
+
+@table @asis
+@item @code{id} (default: @code{""})
+An identifier for ether configuration fields to refer to this key. IDs must
+be unique and must not be empty.
+
+@item @code{address} (default: @code{'()})
+An ordered list of IP addresses, network subnets, or network ranges
+represented with strings.  The query must match one of them.  Empty value
+means that address match is not required.
+
+@item @code{key} (default: @code{'()})
+An ordered list of references to keys represented with strings.  The string
+must match a key ID defined in a @code{knot-key-configuration}.  No key
+means that a key is not require to match that ACL.
+
+@item @code{action} (default: @code{'()})
+An ordered list of actions that are permitted or forbidden by this ACL.
+Possible values are lists of zero or more elements from @code{'transfer},
+@code{'notify} and @code{'update}.
+
+@item @code{deny?} (default: @code{#f})
+When true, the ACL defines restrictions.  Listed actions are forbidden.
+When false, listed actions are allowed.
+
+@end table
+@end deftp
+
+@deftp {Data Type} zone-entry
+Data type represnting a record entry in a zone file.  This type has the
+following parameters:
+
+@table @asis
+@item @code{name} (default: @code{"@@"})
+The name of the record.  @code{"@@"} refers to the origin of the zone.
+Names are relative to the origin of the zone.  For example, in the
+@code{example.org} zone, @code{"ns.example.org"} actually refers to
+@code{ns.example.org.example.org}.  Names ending with a dot are absolute,
+which means that @code{"ns.example.org."} refers to @code{ns.example.org}.
+
+@item @code{ttl} (default: @code{""})
+The Time-To-Live (TTL) of this record.  If not set, the default TTL is used.
+
+@item @code{class} (default: @code{"IN"})
+The class of the record.  Knot currently supports only @code{"IN"} and
+partially @code{"CH"}.
+
+@item @code{type} (default: @code{"A"})
+The type of the record.  Common types include A (IPv4 address), AAAA (IPv6
+address), NS (Name Server) and MX (Mail eXchange).  Many other types are
+defined.
+
+@item @code{data} (default: @code{""})
+The data contained in the record.  For instance an IP address associated
+with an A record, or a domain name associated with an NS record.  Remember
+that domain names are relative to the origin unless they end with a dot.
+
+@end table
+@end deftp
+
+@deftp {Data Type} zone-file
+Data type representing the content of a zone file.  This type has the
+following parameters:
+
+@table @asis
+@item @code{entries} (default: @code{'()})
+The list of entries.  The SOA record is taken care of, so you don't need to
+put it in the list of entries.  This list should probably contain an entry
+for your primary authoritative DNS server.  Other than using a list of
+entries directly, you can use @code{define-zone-entries} to define a object
+containing the list of entries more easily, that you can later pass to the
+@code{entries} field of the @code{zone-file}.
+
+@item @code{origin} (default: @code{""})
+The name of your zone.  This parameter cannot be empty.
+
+@item @code{ns} (default: @code{"ns"})
+The domain of your primary authoritative DNS server.  The name is relative
+to the origin, unless it ends with a dot.  It is mandatory that this primary
+DNS server corresponds to an NS record in the zone and that it is associated
+to an IP address in the list of entries.
+
+@item @code{mail} (default: @code{"hostmaster"})
+An email address people can contact you at, as the owner of the zone.  This
+is translated as @code{<mail>@@<origin>}.
+
+@item @code{serial} (default: @code{1})
+The serial number of the zone.  As this is used to keep track of changes by
+both slaves and resolvers, it is mandatory that it @emph{never} decreases.
+Always increment it when you make a change in your zone.
+
+@item @code{refresh} (default: @code{(* 2 24 3600)})
+The frequency at which slaves will do a zone transfer.  This value is a
+number of seconds.  It can be computed by multiplications or with
+@code{(string->duration)}.
+
+@item @code{retry} (default: @code{(* 15 60)})
+The period after which a slave will retry to contact its master when it
+fails to do so a first time.
+
+@item @code{expiry} (default: @code{(* 14 24 3600)})
+Default TTL of records.  Existing records are considered correct for at most
+this amount of time.  After this period, resolvers will invalidate their
+cache and check again that it still exists.
+
+@item @code{nx} (default: @code{3600})
+Default TTL of inexistant records.  This delay is usually short because you
+want your new domains to reach everyone quickly.
+
+@end table
+@end deftp
+
+@deftp {Data Type} knot-remote-configuration
+Data type representing a remote configuration.  This type has the following
+parameters:
+
+@table @asis
+@item @code{id} (default: @code{""})
+An identifier for other configuration fields to refer to this remote. IDs
+must be unique and must not be empty.
+
+@item @code{address} (default: @code{'()})
+An ordered list of destination IP addresses.  Addresses are tried in
+sequence.  An optional port can be given with the @@ separator.  For
+instance: @code{(list "1.2.3.4" "2.3.4.5@@53")}.  Default port is 53.
+
+@item @code{via} (default: @code{'()})
+An ordered list of source IP addresses.  An empty list will have Knot choose
+an appropriate source IP.  An optional port can be given with the @@
+separator.  The default is to choose at random.
+
+@item @code{key} (default: @code{#f})
+A reference to a key, that is a string containing the identifier of a key
+defined in a @code{knot-key-configuration} field.
+
+@end table
+@end deftp
+
+@deftp {Data Type} knot-keystore-configuration
+Data type representing a keystore to hold dnssec keys.  This type has the
+following parameters:
+
+@table @asis
+@item @code{id} (default: @code{""})
+The id of the keystore.  It must not be empty.
+
+@item @code{backend} (default: @code{'pem})
+The backend to store the keys in.  Can be @code{'pem} or @code{'pkcs11}.
+
+@item @code{config} (default: @code{"/var/lib/knot/keys/keys"})
+The configuration string of the backend.  An example for the PKCS#11 is:
+@code{"pkcs11:token=knot;pin-value=1234
+/gnu/store/.../lib/pkcs11/libsofthsm2.so"}.  For the pem backend, the string
+reprensents a path in the file system.
+
+@end table
+@end deftp
+
+@deftp {Data Type} knot-policy-configuration
+Data type representing a dnssec policy.  Knot DNS is able to automatically
+sign your zones.  It can either generate and manage your keys automatically
+or use keys that you generate.
+
+Dnssec is usually implemented using two keys: a Key Signing Key (KSK) that
+is used to sign the second, and a Zone Signing Key (ZSK) that is used to
+sign the zone.  In order to be trusted, the KSK needs to be present in the
+parent zone (usually a top-level domain).  If your registrar supports
+dnssec, you will have to send them your KSK's hash so they can add a DS
+record in their zone.  This is not automated and need to be done each time
+you change your KSK.
+
+The policy also defines the lifetime of keys.  Usually, ZSK can be changed
+easily and use weaker cryptographic functions (they use lower parameters) in
+order to sign records quickly, so they are changed often.  The KSK however
+requires manual interaction with the registrar, so they are changed less
+often and use stronger parameters because they sign only one record.
+
+This type has the following parameters:
+
+@table @asis
+@item @code{id} (default: @code{""})
+The id of the policy.  It must not be empty.
+
+@item @code{keystore} (default: @code{"default"})
+A reference to a keystore, that is a string containing the identifier of a
+keystore defined in a @code{knot-keystore-configuration} field.  The
+@code{"default"} identifier means the default keystore (a kasp database that
+was setup by this service).
+
+@item @code{manual?} (default: @code{#f})
+Whether the key management is manual or automatic.
+
+@item @code{single-type-signing?} (default: @code{#f})
+When @code{#t}, use the Single-Type Signing Scheme.
+
+@item @code{algorithm} (default: @code{"ecdsap256sha256"})
+An algorithm of signing keys and issued signatures.
+
+@item @code{ksk-size} (default: @code{256})
+The length of the KSK.  Note that this value is correct for the default
+algorithm, but would be unsecure for other algorithms.
+
+@item @code{zsk-size} (default: @code{256})
+The length of the ZSK.  Note that this value is correct for the default
+algorithm, but would be unsecure for other algorithms.
+
+@item @code{dnskey-ttl} (default: @code{'default})
+The TTL value for DNSKEY records added into zone apex.  The special
+@code{'default} value means same as the zone SOA TTL.
+
+@item @code{zsk-lifetime} (default: @code{(* 30 24 3600)})
+The period between ZSK publication and the next rollover initiation.
+
+@item @code{propagation-delay} (default: @code{(* 24 3600)})
+An extra delay added for each key rollover step.  This value should be high
+enough to cover propagation of data from the master server to all slaves.
+
+@item @code{rrsig-lifetime} (default: @code{(* 14 24 3600)})
+A validity period of newly issued signatures.
+
+@item @code{rrsig-refresh} (default: @code{(* 7 24 3600)})
+A period how long before a signature expiration the signature will be
+refreshed.
+
+@item @code{nsec3?} (default: @code{#f})
+When @code{#t}, NSEC3 will be used instead of NSEC.
+
+@item @code{nsec3-iterations} (default: @code{5})
+The number of additional times the hashing is performed.
+
+@item @code{nsec3-salt-length} (default: @code{8})
+The length of a salt field in octets, which is appended to the original
+owner name before hashing.
+
+@item @code{nsec3-salt-lifetime} (default: @code{(* 30 24 3600)})
+The validity period of newly issued salt field.

+@deftp {Data Type} knot-zone-configuration
+Data type representing a zone served by Knot.  This type has the following
+parameters:
+
+@table @asis
+@item @code{domain} (default: @code{""})
+The domain served by this configuration.  It must not be empty.
+
+@item @code{file} (default: @code{""})

+zones.  Empty means default location that depends on the domain name.
+
+@item @code{zone} (default: @code{(zone-file)})
+The content of the zone file.  This parameter is ignored by slave zones.  It
+must contain a zone-file record.
+

+@subsubsection Continuous Integration
+
+@cindex continuous integration
+@uref{https://notabug.org/mthl/cuirass, Cuirass} est un outil d'intégration
+continue pour Guix. On peut l'utiliser aussi bien pour le développement que

+
+The @code{(gnu services cuirass)} module provides the following service.
+
+@defvr {Scheme Procedure} cuirass-service-type
+The type of the Cuirass service.  Its value must be a
+@code{cuirass-configuration} object, as described below.
+@end defvr
+
+To add build jobs, you have to set the @code{specifications} field of the
+configuration.  Here is an example of a service defining a build job based
+on a specification that can be found in Cuirass source tree.  This service
+polls the Guix repository and builds a subset of the Guix packages, as
+prescribed in the @file{gnu-system.scm} example spec:
+
+@example
+(let ((spec #~((#:name . "guix")

+  (service cuirass-service-type
+           (cuirass-configuration
+            (specifications #~(list '#$spec)))))
+@end example
+
+While information related to build jobs is located directly in the
+specifications, global settings for the @command{cuirass} process are
+accessible in other @code{cuirass-configuration} fields.
+

+@node Power management Services
+@subsubsection Power management Services
+
+@cindex power management with TLP
+The @code{(gnu services pm)} module provides a Guix service definition for
+the Linux power management tool TLP.
+
+TLP enables various powersaving modes in userspace and kernel.  Contrary to
+@code{upower-service}, it is not a passive, monitoring tool, as it will
+apply custom settings each time a new power source is detected.  More
+information can be found at @uref{http://linrunner.de/en/tlp/tlp.html, TLP
+home page}.
+
+@deffn {Scheme Variable} tlp-service-type
+The service type for the TLP tool.  Its value should be a valid TLP
+configuration (see below).  To use the default settings, simply write:
+@example
+(service tlp-service-type)
+@end example
+@end deffn
+
+By default TLP does not need much configuration but most TLP parameters can
+be tweaked using @code{tlp-configuration}.
+
+Each parameter definition is preceded by its type; for example,
+@samp{boolean foo} indicates that the @code{foo} parameter should be
+specified as a boolean.  Types starting with @code{maybe-} denote parameters
+that won't show up in TLP config file when their value is @code{'disabled}.
+
+@c The following documentation was initially generated by
+@c (generate-tlp-documentation) in (gnu services pm).  Manually maintained
+@c documentation is better, so we shouldn't hesitate to edit below as
+@c needed.  However if the change you want to make to this documentation
+@c can be done in an automated way, it's probably easier to change
+@c (generate-documentation) than to make it below and have to deal with
+@c the churn as TLP updates.

+
+@deftypevr {@code{tlp-configuration} parameter} package tlp

+@subsubheading Transparent Emulation with QEMU
+
+@cindex emulation
+@cindex @code{binfmt_misc}
+@code{qemu-binfmt-service-type} provides support for transparent emulation
+of program binaries built for different architectures---e.g., it allows you
+to transparently execute an ARMv7 program on an x86_64 machine.  It achieves
+this by combining the @uref{https://www.qemu.org, QEMU} emulator and the
+@code{binfmt_misc} feature of the kernel Linux.
+
+@defvr {Scheme Variable} qemu-binfmt-service-type
+This is the type of the QEMU/binfmt service for transparent emulation.  Its
+value must be a @code{qemu-binfmt-configuration} object, which specifies the
+QEMU package to use as well as the architecture we want to emulated:
+
+@example
+(service qemu-binfmt-service-type
+         (qemu-binfmt-configuration
+           (platforms (lookup-qemu-platforms "arm" "aarch64" "ppc"))))
+@end example
+
+In this example, we enable transparent emulation for the ARM and aarch64
+platforms.  Running @code{herd stop qemu-binfmt} turns it off, and running
+@code{herd start qemu-binfmt} turns it back on (@pxref{Invoking herd, the
+@command{herd} command,, shepherd, The GNU Shepherd Manual}).
+@end defvr
+
+@deftp {Data Type} qemu-binfmt-configuration
+This is the configuration for the @code{qemu-binfmt} service.
+
+@table @asis
+@item @code{platforms} (default: @code{'()})
+The list of emulated QEMU platforms.  Each item must be a @dfn{platform
+object} as returned by @code{lookup-qemu-platforms} (see below).
+
+@item @code{guix-support?} (default: @code{#f})
+When it is true, QEMU and all its dependencies are added to the build
+environment of @command{guix-daemon} (@pxref{Invoquer guix-daemon,
+@code{--chroot-directory} option}).  This allows the @code{binfmt_misc}
+handlers to be used within the build environment, which in turn means that
+you can transparently build programs for another architecture.
+
+For example, let's suppose you're on an x86_64 machine and you have this
+service:
+
+@example
+(service qemu-binfmt-service-type
+         (qemu-binfmt-configuration
+           (platforms (lookup-qemu-platforms "arm"))
+           (guix-support? #t)))
+@end example
+
+You can run:
+
+@example
+guix build -s armhf-linux inkscape
+@end example
+
+@noindent
+and it will build Inkscape for ARMv7 @emph{as if it were a native build},
+transparently using QEMU to emulate the ARMv7 CPU.  Pretty handy if you'd
+like to test a package build for an architecture you don't have access to!
+
+@item @code{qemu} (default: @code{qemu})
+The QEMU package to use.
+@end table
+@end deftp
+
+@deffn {Scheme Procedure} lookup-qemu-platforms @var{platforms}@dots{}
+Return the list of QEMU platform objects corresponding to
+@var{platforms}@dots{}.  @var{platforms} must be a list of strings
+corresponding to platform names, such as @code{"arm"}, @code{"sparc"},
+@code{"mips64el"}, and so on.

+@node Version Control Services
+@subsubsection Version Control Services
+
+The @code{(gnu services version-control)} module provides a service to allow
+remote access to local Git repositories.  There are three options: the
+@code{git-daemon-service}, which provides access to repositories via the
+@code{git://} unsecured TCP-based protocol, extending the @code{nginx} web
+server to proxy some requests to @code{git-http-backend}, or providing a web
+interface with @code{cgit-service-type}.
+
+@deffn {Scheme Procedure} git-daemon-service [#:config (git-daemon-configuration)]
+
+Return a service that runs @command{git daemon}, a simple TCP server to
+expose repositories over the Git protocol for anonymous access.
+
+The optional @var{config} argument should be a
+@code{<git-daemon-configuration>} object, by default it allows read-only
+access to exported@footnote{By creating the magic file
+"git-daemon-export-ok" in the repository directory.} repositories under
+@file{/srv/git}.
+
+@end deffn

+the @file{git-daemon-export-ok} file.
+
+@item @code{base-path} (default: @file{/srv/git})
+Whether to remap all the path requests as relative to the given path.  If
+you run git daemon with @var{(base-path "/srv/git")} on example.com, then if
+you later try to pull @code{git://example.com/hello.git}, git daemon will
+interpret the path as @code{/srv/git/hello.git}.
+
+@item @code{user-path} (default: @var{#f})
+Whether to allow @code{~user} notation to be used in requests.  When
+specified with empty string, requests to @code{git://host/~alice/foo} is
+taken as a request to access @code{foo} repository in the home directory of
+user @code{alice}.  If @var{(user-path "path")} is specified, the same
+request is taken as a request to access @code{path/foo} repository in the
+home directory of user @code{alice}.
+
+@item @code{listen} (default: @var{'()})
+Whether to listen on specific IP addresses or hostnames, defaults to all.

+Extra options will be passed to @code{git daemon}, please run @command{man
+git-daemon} for more information.
+
+@end table
+@end deftp
+
+The @code{git://} protocol lacks authentication.  When you pull from a

+receive was modified is really coming from the specified host, and you have
+your connection is subject to eavesdropping.  It's better to use an
+authenticated and encrypted transport, such as @code{https}.  Although Git
+allows you to serve repositories using unsophisticated file-based web
+servers, there is a faster protocol implemented by the
+@code{git-http-backend} program.  This program is the back-end of a proper
+Git web service.  It is designed to sit behind a FastCGI proxy.  @xref{Web
+Services}, for more on running the necessary @code{fcgiwrap} daemon.

+@node Programmes setuid
+@subsection Programmes setuid
+
+@cindex setuid programs
+Some programs need to run with ``root'' privileges, even when they are
+launched by unprivileged users.  A notorious example is the @command{passwd}
+program, which users can run to change their password, and which needs to
+access the @file{/etc/passwd} and @file{/etc/shadow} files---something
+normally restricted to root, for obvious security reasons.  To address that,
+these executables are @dfn{setuid-root}, meaning that they always run with
+root privileges (@pxref{How Change Persona,,, libc, The GNU C Library
+Reference Manual}, for more info about the setuid mechanism.)
+
+The store itself @emph{cannot} contain setuid programs: that would be a
+security issue since any user on the system can write derivations that
+populate the store (@pxref{Le dépôt}).  Thus, a different mechanism is
+used: instead of changing the setuid bit directly on files that are in the
+store, we let the system administrator @emph{declare} which programs should
+be setuid root.
+
+The @code{setuid-programs} field of an @code{operating-system} declaration
+contains a list of G-expressions denoting the names of programs to be
+setuid-root (@pxref{Utiliser le système de configuration}).  For instance, the
+@command{passwd} program, which is part of the Shadow package, can be
+designated by this G-expression (@pxref{G-Expressions}):
+
+@example
+#~(string-append #$shadow "/bin/passwd")
+@end example
+
+A default set of setuid programs is defined by the @code{%setuid-programs}
+variable of the @code{(gnu system)} module.
+
+@defvr {Scheme Variable} %setuid-programs
+A list of G-expressions denoting common programs that are setuid-root.
+
+The list includes commands such as @command{passwd}, @command{ping},
+@command{su}, and @command{sudo}.
+@end defvr
+
+Under the hood, the actual setuid programs are created in the
+@file{/run/setuid-programs} directory at system activation time.  The files
+in this directory refer to the ``real'' binaries, which are in the store.

+@cindex HTTPS, certificates
+@cindex X.509 certificates
+@cindex TLS
+Web servers available over HTTPS (that is, HTTP over the transport-layer
+security mechanism, TLS) send client programs an @dfn{X.509 certificate}
+that the client can then use to @emph{authenticate} the server.  To do that,
+clients verify that the server's certificate is signed by a so-called
+@dfn{certificate authority} (CA).  But to verify the CA's signature, clients
+must have first acquired the CA's certificate.
+
+Web browsers such as GNU@tie{}IceCat include their own set of CA
+certificates, such that they are able to verify CA signatures
+out-of-the-box.
+
+However, most other programs that can talk HTTPS---@command{wget},
+@command{git}, @command{w3m}, etc.---need to be told where CA certificates
+can be found.
+
+@cindex @code{nss-certs}
+In GuixSD, this is done by adding a package that provides certificates to
+the @code{packages} field of the @code{operating-system} declaration
+(@pxref{Référence de système d'exploitation}).  GuixSD includes one such package,
+@code{nss-certs}, which is a set of CA certificates provided as part of

+Note that it is @emph{not} part of @var{%base-packages}, so you need to
+explicitly add it.  The @file{/etc/ssl/certs} directory, which is where most
+applications and libraries look for certificates by default, points to the
+certificates installed globally.
+
+Unprivileged users, including users of Guix on a foreign distro, can also
+install their own certificate package in their profile.  A number of
+environment variables need to be defined so that applications and libraries
+know where to find them.  Namely, the OpenSSL library honors the
+@code{SSL_CERT_DIR} and @code{SSL_CERT_FILE} variables.  Some applications
+add their own environment variables; for instance, the Git version control
+system honors the certificate bundle pointed to by the @code{GIT_SSL_CAINFO}
+environment variable.  Thus, you would typically run something like:
+
+@example
+$ guix package -i nss-certs
+$ export SSL_CERT_DIR="$HOME/.guix-profile/etc/ssl/certs"
+$ export SSL_CERT_FILE="$HOME/.guix-profile/etc/ssl/certs/ca-certificates.crt"
+$ export GIT_SSL_CAINFO="$SSL_CERT_FILE"
+@end example
+
+As another example, R requires the @code{CURL_CA_BUNDLE} environment
+variable to point to a certificate bundle, so you would have to run
+something like this:
+
+@example
+$ guix package -i nss-certs
+$ export CURL_CA_BUNDLE="$HOME/.guix-profile/etc/ssl/certs/ca-certificates.crt"
+@end example
+
+For other applications you may want to look up the required environment
+variable in the relevant documentation.

+@node Name Service Switch
+@subsection Name Service Switch
+
+@cindex name service switch
+@cindex NSS
+The @code{(gnu system nss)} module provides bindings to the configuration
+file of the libc @dfn{name service switch} or @dfn{NSS} (@pxref{NSS
+Configuration File,,, libc, The GNU C Library Reference Manual}).  In a
+nutshell, the NSS is a mechanism that allows libc to be extended with new
+``name'' lookup methods for system databases, which includes host names,
+service names, user accounts, and more (@pxref{Name Service Switch, System
+Databases and Name Service Switch,, libc, The GNU C Library Reference
+Manual}).
+
+The NSS configuration specifies, for each system database, which lookup
+method is to be used, and how the various methods are chained together---for
+instance, under which circumstances NSS should try the next method in the
+list.  The NSS configuration is given in the @code{name-service-switch}
+field of @code{operating-system} declarations (@pxref{Référence de système d'exploitation, @code{name-service-switch}}).
+
+@cindex nss-mdns
+@cindex .local, host name lookup
+As an example, the declaration below configures the NSS to use the
+@uref{http://0pointer.de/lennart/projects/nss-mdns/, @code{nss-mdns}
+back-end}, which supports host name lookups over multicast DNS (mDNS)  for
+host names ending in @code{.local}:
+
+@example
+(name-service-switch
+   (hosts (list %files    ;first, check /etc/hosts
+
+                ;; If the above did not succeed, try
+                ;; with 'mdns_minimal'.
+                (name-service
+                  (name "mdns_minimal")
+
+                  ;; 'mdns_minimal' is authoritative for
+                  ;; '.local'.  When it returns "not found",
+                  ;; no need to try the next methods.
+                  (reaction (lookup-specification
+                             (not-found => return))))
+
+                ;; Then fall back to DNS.
+                (name-service
+                  (name "dns"))
+
+                ;; Finally, try with the "full" 'mdns'.
+                (name-service
+                  (name "mdns")))))
+@end example
+
+Do not worry: the @code{%mdns-host-lookup-nss} variable (see below)
+contains this configuration, so you will not have to type it if all you want
+is to have @code{.local} host lookup working.
+
+Note that, in this case, in addition to setting the
+@code{name-service-switch} of the @code{operating-system} declaration, you
+also need to use @code{avahi-service} (@pxref{Networking Services,
+@code{avahi-service}}), or @var{%desktop-services}, which includes it
+(@pxref{Desktop Services}).  Doing this makes @code{nss-mdns} accessible to
+the name service cache daemon (@pxref{Services de base, @code{nscd-service}}).
+
+For convenience, the following variables provide typical NSS configurations.
+
+@defvr {Scheme Variable} %default-nss
+This is the default name service switch configuration, a
+@code{name-service-switch} object.
+@end defvr
+
+@defvr {Scheme Variable} %mdns-host-lookup-nss
+This is the name service switch configuration with support for host name
+lookup over multicast DNS (mDNS) for host names ending in @code{.local}.
+@end defvr
+
+The reference for name service switch configuration is given below.  It is a
+direct mapping of the configuration file format of the C library , so please
+refer to the C library manual for more information (@pxref{NSS Configuration
+File,,, libc, The GNU C Library Reference Manual}).  Compared to the
+configuration file format of libc NSS, it has the advantage not only of
+adding this warm parenthetic feel that we like, but also static checks: you
+will know about syntax errors and typos as soon as you run @command{guix
+system}.
+
+@deftp {Data Type} name-service-switch
+
+This is the data type representation the configuration of libc's name
+service switch (NSS).  Each field below represents one of the supported

+@node Disque de RAM initial
+@subsection Disque de RAM initial
+
+@cindex initrd
+@cindex initial RAM disk
+For bootstrapping purposes, the Linux-Libre kernel is passed an @dfn{initial
+RAM disk}, or @dfn{initrd}.  An initrd contains a temporary root file system
+as well as an initialization script.  The latter is responsible for mounting
+the real root file system, and for loading any kernel modules that may be
+needed to achieve that.
+
+The @code{initrd-modules} field of an @code{operating-system} declaration
+allows you to specify Linux-libre kernel modules that must be available in
+the initrd.  In particular, this is where you would list modules needed to
+actually drive the hard disk where your root partition is---although the
+default value of @code{initrd-modules} should cover most use cases.  For
+example, assuming you need the @code{megaraid_sas} module in addition to the
+default modules to be able to access your root file system, you would write:
+
+@example
+(operating-system
+  ;; @dots{}
+  (initrd-modules (cons "megaraid_sas" %base-initrd-modules)))
+@end example
+
+@defvr {Scheme Variable} %base-initrd-modules
+This is the list of kernel modules included in the initrd by default.
+@end defvr
+
+Furthermore, if you need lower-level customization, the @code{initrd} field
+of an @code{operating-system} declaration allows you to specify which initrd
+you would like to use.  The @code{(gnu system linux-initrd)} module provides
+three ways to build an initrd: the high-level @code{base-initrd} procedure
+and the low-level @code{raw-initrd} and @code{expression->initrd}
+procedures.
+
+The @code{base-initrd} procedure is intended to cover most common uses.  For
+example, if you want to add a bunch of kernel modules to be loaded at boot
+time, you can define the @code{initrd} field of the operating system
+declaration like this:
+
+@example
+(initrd (lambda (file-systems . rest)
+          ;; Create a standard initrd but set up networking
+          ;; with the parameters QEMU expects by default.
+          (apply base-initrd file-systems
+                 #:qemu-networking? #t
+                 rest)))
+@end example
+
+The @code{base-initrd} procedure also handles common use cases that involves
+using the system as a QEMU guest, or as a ``live'' system with volatile root
+file system.
+
+The @code{base-initrd} procedure is built from @code{raw-initrd} procedure.
+Unlike @code{base-initrd}, @code{raw-initrd} doesn't do anything high-level,
+such as trying to guess which kernel modules and packages should be included
+to the initrd. An example use of @code{raw-initrd} is when a user has a
+custom Linux kernel configuration and default kernel modules included by
+@code{base-initrd} are not available.
+
+The initial RAM disk produced by @code{base-initrd} or @code{raw-initrd}
+honors several options passed on the Linux kernel command line (that is,
+arguments passed @i{via} the @code{linux} command of GRUB, or the
+@code{-append} option of QEMU), notably:
+
+@table @code
+@item --load=@var{boot}
+Tell the initial RAM disk to load @var{boot}, a file containing a Scheme
+program, once it has mounted the root file system.
+
+GuixSD uses this option to yield control to a boot program that runs the
+service activation programs and then spawns the GNU@tie{}Shepherd, the
+initialization system.
+
+@item --root=@var{root}
+Mount @var{root} as the root file system.  @var{root} can be a device name
+like @code{/dev/sda1}, a file system label, or a file system UUID.
+
+@item --system=@var{system}
+Have @file{/run/booted-system} and @file{/run/current-system} point to
+@var{system}.
+
+@item modprobe.blacklist=@var{modules}@dots{}
+@cindex module, black-listing
+@cindex black list, of kernel modules
+Instruct the initial RAM disk as well as the @command{modprobe} command
+(from the kmod package) to refuse to load @var{modules}.  @var{modules} must
+be a comma-separated list of module names---e.g., @code{usbkbd,9pnet}.
+
+@item --repl
+Start a read-eval-print loop (REPL) from the initial RAM disk before it
+tries to load kernel modules and to mount the root file system.  Our
+marketing team calls it @dfn{boot-to-Guile}.  The Schemer in you will love
+it.  @xref{Using Guile Interactively,,, guile, GNU Guile Reference Manual},
+for more information on Guile's REPL.
+
+@end table
+
+Now that you know all the features that initial RAM disks produced by
+@code{base-initrd} and @code{raw-initrd} provide, here is how to use it and

+
+When @var{qemu-networking?} is true, set up networking with the standard
+QEMU parameters.  When @var{virtio?} is true, load additional modules so
+that the initrd can be used as a QEMU guest with para-virtualized I/O

+
+@var{qemu-networking?} and @var{volatile-root?} behaves as in

+
+As for @command{guix package --search}, the result is written in
+@code{recutils} format, which makes it easy to filter the output
+(@pxref{Top, GNU recutils databases,, recutils, GNU recutils manual}).
+
+@item reconfigure
+Build the operating system described in @var{file}, activate it, and switch
+to it@footnote{This action (and the related actions @code{switch-generation}
+and @code{roll-back}) are usable only on systems already running GuixSD.}.
+
+This effects all the configuration specified in @var{file}: user accounts,
+system services, global package list, setuid programs, etc.  The command
+starts system services specified in @var{file} that are not currently
+running; if a service is currently running, it does not attempt to upgrade
+it since this would not be possible without stopping it first.
+
+This command creates a new generation whose number is one greater than the
+current generation (as reported by @command{guix system list-generations}).
+If that generation already exists, it will be overwritten.  This behavior
+mirrors that of @command{guix package} (@pxref{Invoquer guix package}).
+
+It also adds a bootloader menu entry for the new OS configuration, ---unless
+@option{--no-bootloader} is passed.  For GRUB, it moves entries for older
+configurations to a submenu, allowing you to choose an older system
+generation at boot time should you need it.
+
+@quotation Note
+@c The paragraph below refers to the problem discussed at
+@c <http://lists.gnu.org/archive/html/guix-devel/2014-08/msg00057.html>.
+It is highly recommended to run @command{guix pull} once before you run
+@command{guix system reconfigure} for the first time (@pxref{Invoquer guix pull}).  Failing to do that you would see an older version of Guix once
+@command{reconfigure} has completed.
+@end quotation
+
+@item switch-generation
+@cindex generations
+Switch to an existing system generation.  This action atomically switches
+the system profile to the specified system generation.  It also rearranges
+the system's existing bootloader menu entries.  It makes the menu entry for
+the specified system generation the default, and it moves the entries for
+the other generatiors to a submenu, if supported by the bootloader being
+used.  The next time the system boots, it will use the specified system
+generation.
+
+The bootloader itself is not being reinstalled when using this command.
+Thus, the installed bootloader is used with an updated configuration file.
+
+The target generation can be specified explicitly by its generation number.
+For example, the following invocation would switch to system generation 7:
+
+@example
+guix system switch-generation 7
+@end example
+
+The target generation can also be specified relative to the current
+generation with the form @code{+N} or @code{-N}, where @code{+3} means ``3
+generations ahead of the current generation,'' and @code{-1} means ``1
+generation prior to the current generation.'' When specifying a negative
+value such as @code{-1}, you must precede it with @code{--} to prevent it
+from being parsed as an option.  For example:
+
+@example
+guix system switch-generation -- -1
+@end example
+
+Currently, the effect of invoking this action is @emph{only} to switch the
+system profile to an existing generation and rearrange the bootloader menu
+entries.  To actually start using the target system generation, you must
+reboot after running this action.  In the future, it will be updated to do
+the same things as @command{reconfigure}, like activating and deactivating
+services.
+
+This action will fail if the specified generation does not exist.
+
+@item roll-back
+@cindex rolling back
+Switch to the preceding system generation.  The next time the system boots,
+it will use the preceding system generation.  This is the inverse of
+@command{reconfigure}, and it is exactly the same as invoking
+@command{switch-generation} with an argument of @code{-1}.
+
+Currently, as with @command{switch-generation}, you must reboot after
+running this action to actually start using the preceding system generation.
+
+@item build
+Build the derivation of the operating system, which includes all the
+configuration files and programs needed to boot and run the system.  This
+action does not actually install anything.
+
+@item init
+Populate the given directory with all the files necessary to run the
+operating system specified in @var{file}.  This is useful for first-time
+installations of GuixSD.  For instance:
+
+@example
+guix system init my-os-config.scm /mnt
+@end example
+
+copies to @file{/mnt} all the store items required by the configuration
+specified in @file{my-os-config.scm}.  This includes configuration files,
+packages, and so on.  It also creates other essential files needed for the
+system to operate correctly---e.g., the @file{/etc}, @file{/var}, and
+@file{/run} directories, and the @file{/bin/sh} file.
+
+This command also installs bootloader on the target specified in
+@file{my-os-config}, unless the @option{--no-bootloader} option was passed.
+
+@item vm
+@cindex virtual machine
+@cindex VM
+@anchor{guix system vm}
+Build a virtual machine that contains the operating system declared in
+@var{file}, and return a script to run that virtual machine (VM).  Arguments
+given to the script are passed to QEMU as in the example below, which
+enables networking and requests 1@tie{}GiB of RAM for the emulated machine:
+
+@example
+$ /gnu/store/@dots{}-run-vm.sh -m 1024 -net user
+@end example
+
+The VM shares its store with the host system.
+
+Additional file systems can be shared between the host and the VM using the
+@code{--share} and @code{--expose} command-line options: the former
+specifies a directory to be shared with write access, while the latter
+provides read-only access to the shared directory.
+
+The example below creates a VM in which the user's home directory is
+accessible read-only, and where the @file{/exchange} directory is a
+read-write mapping of @file{$HOME/tmp} on the host:
+
+@example
+guix system vm my-config.scm \
+   --expose=$HOME --share=$HOME/tmp=/exchange
+@end example
+
+On GNU/Linux, the default is to boot directly to the kernel; this has the
+advantage of requiring only a very tiny root disk image since the store of
+the host can then be mounted.
+
+The @code{--full-boot} option forces a complete boot sequence, starting with
+the bootloader.  This requires more disk space since a root image containing
+at least the kernel, initrd, and bootloader data files must be created.  The
+@code{--image-size} option can be used to specify the size of the image.
+
+@cindex System images, creation in various formats
+@cindex Creating system images in various formats
+@item vm-image
+@itemx disk-image
+@itemx docker-image
+Return a virtual machine, disk image, or Docker image of the operating
+system declared in @var{file} that stands alone.  By default, @command{guix
+system} estimates the size of the image needed to store the system, but you
+can use the @option{--image-size} option to specify a value.  Docker images
+are built to contain exactly what they need, so the @option{--image-size}
+option is ignored in the case of @code{docker-image}.
+
+You can specify the root file system type by using the
+@option{--file-system-type} option.  It defaults to @code{ext4}.
+
+When using @code{vm-image}, the returned image is in qcow2 format, which the
+QEMU emulator can efficiently use. @xref{Lancer GuixSD dans une VM}, for more
+information on how to run the image in a virtual machine.
+
+When using @code{disk-image}, a raw disk image is produced; it can be copied
+as is to a USB stick, for instance.  Assuming @code{/dev/sdc} is the device
+corresponding to a USB stick, one can copy the image to it using the
+following command:
+
+@example
+# dd if=$(guix system disk-image my-os.scm) of=/dev/sdc
+@end example
+
+When using @code{docker-image}, a Docker image is produced.  Guix builds the
+image from scratch, not from a pre-existing Docker base image.  As a result,
+it contains @emph{exactly} what you define in the operating system
+configuration file.  You can then load the image and launch a Docker
+container using commands like the following:
+
+@example
+image_id="$(docker load < guixsd-docker-image.tar.gz)"
+docker run -e GUIX_NEW_SYSTEM=/var/guix/profiles/system \\
+    --entrypoint /var/guix/profiles/system/profile/bin/guile \\
+    $image_id /var/guix/profiles/system/boot
+@end example
+
+This command starts a new Docker container from the specified image.  It
+will boot the GuixSD system in the usual manner, which means it will start
+any services you have defined in the operating system configuration.
+Depending on what you run in the Docker container, it may be necessary to
+give the container additional permissions.  For example, if you intend to
+build software using Guix inside of the Docker container, you may need to
+pass the @option{--privileged} option to @code{docker run}.
+
+@item container
+Return a script to run the operating system declared in @var{file} within a
+container.  Containers are a set of lightweight isolation mechanisms
+provided by the kernel Linux-libre.  Containers are substantially less
+resource-demanding than full virtual machines since the kernel, shared
+objects, and other resources can be shared with the host system; this also
+means they provide thinner isolation.
+
+Currently, the script must be run as root in order to support more than a
+single user and group.  The container shares its store with the host system.
+
+As with the @code{vm} action (@pxref{guix system vm}), additional file
+systems to be shared between the host and container can be specified using
+the @option{--share} and @option{--expose} options:
+
+@example
+guix system container my-config.scm \
+   --expose=$HOME --share=$HOME/tmp=/exchange
+@end example
+
+@quotation Note
+This option requires Linux-libre 3.19 or newer.

+@itemx -e @var{expr}
+Consider the operating-system @var{expr} evaluates to.  This is an

+This is used to generate the GuixSD installer @pxref{Construire l'image d'installation}).
+
+@item --system=@var{system}

+For the @code{disk-image} action, create a file system of the given

+
+@cindex ISO-9660 format

+For the @code{vm-image} and @code{disk-image} actions, create an image of

+include a unit as a suffix (@pxref{Block size, size specifications,,

+
+When this option is omitted, @command{guix system} computes an estimate of
+the image size as a function of the size of the system declared in
+@var{file}.
+
+@item --root=@var{file}
+@itemx -r @var{file}
+Make @var{file} a symlink to the result, and register it as a garbage

+
+@item --skip-checks
+Skip pre-installation safety checks.
+
+By default, @command{guix system init} and @command{guix system reconfigure}
+perform safety checks: they make sure the file systems that appear in the
+@code{operating-system} declaration actually exist (@pxref{Systèmes de fichiers}),
+and that any Linux kernel modules that may be needed at boot time are listed
+in @code{initrd-modules} (@pxref{Disque de RAM initial}).  Passing this option
+skips these tests altogether.
+
+@item --on-error=@var{strategy}
+Apply @var{strategy} when an error occurs when reading @var{file}.
+@var{strategy} may be one of the following:
+
+@table @code
+@item nothing-special
+Report the error concisely and exit.  This is the default strategy.
+
+@item backtrace
+Likewise, but also display a backtrace.
+
+@item debug
+Report the error and enter Guile's debugger.  From there, you can run

+Once you have built, configured, re-configured, and re-re-configured your

+
+@table @code
+
+@item list-generations
+List a summary of each generation of the operating system available on disk,
+in a human-readable way.  This is similar to the @option{--list-generations}
+option of @command{guix package} (@pxref{Invoquer guix package}).
+
+Optionally, one can specify a pattern, with the same syntax that is used in
+@command{guix package --list-generations}, to restrict the list of
+generations displayed.  For instance, the following command displays
+generations that are up to 10 days old:
+
+@example
+$ guix system list-generations 10d

+@node Lancer GuixSD dans une VM
+@subsection Running GuixSD in a Virtual Machine
+
+@cindex virtual machine
+To run GuixSD in a virtual machine (VM), one can either use the pre-built
+GuixSD VM image distributed at
+@indicateurl{ftp://alpha.gnu.org/guix/guixsd-vm-image-@value{VERSION}.@var{system}.tar.xz}
+, or build their own virtual machine image using @command{guix system
+vm-image} (@pxref{Invoquer guix system}).  The returned image is in qcow2
+format, which the @uref{http://qemu.org/, QEMU emulator} can efficiently
+use.
+
+@cindex QEMU
+If you built your own image, you must copy it out of the store (@pxref{Le dépôt}) and give yourself permission to write to the copy before you can use
+it.  When invoking QEMU, you must choose a system emulator that is suitable
+for your hardware platform.  Here is a minimal QEMU invocation that will
+boot the result of @command{guix system vm-image} on x86_64 hardware:
+
+@example
+$ qemu-system-x86_64 \
+   -net user -net nic,model=virtio \
+   -enable-kvm -m 256 /tmp/qemu-image
+@end example
+
+Here is what each of these options means:
+
+@table @code
+@item qemu-system-x86_64
+This specifies the hardware platform to emulate.  This should match the
+host.
+
+@item -net user
+Enable the unprivileged user-mode network stack.  The guest OS can access
+the host but not vice versa.  This is the simplest way to get the guest OS
+online.
+
+@item -net nic,model=virtio
+You must create a network interface of a given model.  If you do not create
+a NIC, the boot will fail.  Assuming your hardware platform is x86_64, you
+can get a list of available NIC models by running
+@command{qemu-system-x86_64 -net nic,model=help}.
+
+@item -enable-kvm
+If your system has hardware virtualization extensions, enabling the virtual
+machine support (KVM) of the Linux kernel will make things run faster.
+
+@item -m 256
+RAM available to the guest OS, in mebibytes.  Defaults to 128@tie{}MiB,
+which may be insufficient for some operations.
+
+@item /tmp/qemu-image
+The file name of the qcow2 image.
+@end table
+
+The default @command{run-vm.sh} script that is returned by an invocation of
+@command{guix system vm} does not add a @command{-net user} flag by
+default.  To get network access from within the vm add the
+@code{(dhcp-client-service)} to your system definition and start the VM
+using @command{`guix system vm config.scm` -net user}.  An important caveat
+of using @command{-net user} for networking is that @command{ping} will not
+work, because it uses the ICMP protocol.  You'll have to use a different
+command to check for network connectivity, for example @command{guix
+download}.
+
+@subsubsection Connecting Through SSH
+
+@cindex SSH
+@cindex SSH server
+To enable SSH inside a VM you need to add a SSH server like
+@code{(dropbear-service)} or @code{(lsh-service)} to your VM.  The
+@code{(lsh-service}) doesn't currently boot unsupervised.  It requires you
+to type some characters to initialize the randomness generator.  In addition
+you need to forward the SSH port, 22 by default, to the host.  You can do
+this with
+
+@example
+`guix system vm config.scm` -net user,hostfwd=tcp::10022-:22
+@end example
+
+To connect to the VM you can run
+
+@example
+ssh -o UserKnownHostsFile=/dev/null -o StrictHostKeyChecking=no -p 10022
+@end example
+
+The @command{-p} tells @command{ssh} the port you want to connect to.
+@command{-o UserKnownHostsFile=/dev/null} prevents @command{ssh} from
+complaining every time you modify your @command{config.scm} file and the
+@command{-o StrictHostKeyChecking=no} prevents you from having to allow a
+connection to an unknown host every time you connect.
+
+@subsubsection Using @command{virt-viewer} with Spice
+
+As an alternative to the default @command{qemu} graphical client you can use
+the @command{remote-viewer} from the @command{virt-viewer} package.  To
+connect pass the @command{-spice port=5930,disable-ticketing} flag to
+@command{qemu}.  See previous section for further information on how to do
+this.
+
+Spice also allows you to do some nice stuff like share your clipboard with
+your VM.  To enable that you'll also have to pass the following flags to
+@command{qemu}:
+
+@example
+-device virtio-serial-pci,id=virtio-serial0,max_ports=16,bus=pci.0,addr=0x5
+-chardev spicevmc,name=vdagent,id=vdagent
+-device virtserialport,nr=1,bus=virtio-serial0.0,chardev=vdagent,
+name=com.redhat.spice.0
+@end example
+
+You'll also need to add the @pxref{Miscellaneous Services, Spice service}.

+@node Composition de services
+@subsubsection Composition de services
+
+@cindex services
+@cindex daemons
+Here we define a @dfn{service} as, broadly, something that extends the
+functionality of the operating system.  Often a service is a process---a
+@dfn{daemon}---started when the system boots: a secure shell server, a Web
+server, the Guix build daemon, etc.  Sometimes a service is a daemon whose
+execution can be triggered by another daemon---e.g., an FTP server started
+by @command{inetd} or a D-Bus service activated by @command{dbus-daemon}.
+Occasionally, a service does not map to a daemon.  For instance, the
+``account'' service collects user accounts and makes sure they exist when
+the system runs; the ``udev'' service collects device management rules and
+makes them available to the eudev daemon; the @file{/etc} service populates
+the @file{/etc} directory of the system.
+
+@cindex service extensions
+GuixSD services are connected by @dfn{extensions}.  For instance, the secure
+shell service @emph{extends} the Shepherd---the GuixSD initialization
+system, running as PID@tie{}1---by giving it the command lines to start and
+stop the secure shell daemon (@pxref{Networking Services,
+@code{lsh-service}}); the UPower service extends the D-Bus service by
+passing it its @file{.service} specification, and extends the udev service
+by passing it device management rules (@pxref{Desktop Services,
+@code{upower-service}}); the Guix daemon service extends the Shepherd by
+passing it the command lines to start and stop the daemon, and extends the
+account service by passing it a list of required build user accounts
+(@pxref{Services de base}).
+
+All in all, services and their ``extends'' relations form a directed acyclic
+graph (DAG).  If we represent services as boxes and extensions as arrows, a
+typical system might provide something like this:
+
+@image{images/service-graph,,5in,Typical service extension graph.}
+
+@cindex system service
+At the bottom, we see the @dfn{system service}, which produces the directory
+containing everything to run and boot the system, as returned by the
+@command{guix system build} command.  @xref{Référence de service}, to learn
+about the other service types shown here.  @xref{system-extension-graph, the
+@command{guix system extension-graph} command}, for information on how to
+generate this representation for a particular operating system definition.
+
+@cindex service types
+Technically, developers can define @dfn{service types} to express these
+relations.  There can be any number of services of a given type on the
+system---for instance, a system running two instances of the GNU secure
+shell server (lsh) has two instances of @var{lsh-service-type}, with
+different parameters.
+
+The following section describes the programming interface for service types
+and services.
+
+@node Types service et services
+@subsubsection Types service et services
+
+A @dfn{service type} is a node in the DAG described above.  Let us start
+with a simple example, the service type for the Guix build daemon
+(@pxref{Invoquer guix-daemon}):
+
+@example
+(define guix-service-type
+  (service-type
+   (name 'guix)
+   (extensions
+    (list (service-extension shepherd-root-service-type guix-shepherd-service)
+          (service-extension account-service-type guix-accounts)
+          (service-extension activation-service-type guix-activation)))
+   (default-value (guix-configuration))))
+@end example
+
+@noindent
+It defines three things:
+
+@enumerate
+@item
+A name, whose sole purpose is to make inspection and debugging easier.
+
+@item
+A list of @dfn{service extensions}, where each extension designates the
+target service type and a procedure that, given the parameters of the
+service, returns a list of objects to extend the service of that type.
+
+Every service type has at least one service extension.  The only exception
+is the @dfn{boot service type}, which is the ultimate service.
+
+@item
+Optionally, a default value for instances of this type.
+@end enumerate
+
+In this example, @var{guix-service-type} extends three services:
+
+@table @var
+@item shepherd-root-service-type
+The @var{guix-shepherd-service} procedure defines how the Shepherd service
+is extended.  Namely, it returns a @code{<shepherd-service>} object that
+defines how @command{guix-daemon} is started and stopped (@pxref{Services Shepherd}).
+
+@item account-service-type
+This extension for this service is computed by @var{guix-accounts}, which
+returns a list of @code{user-group} and @code{user-account} objects
+representing the build user accounts (@pxref{Invoquer guix-daemon}).
+
+@item activation-service-type
+Here @var{guix-activation} is a procedure that returns a gexp, which is a
+code snippet to run at ``activation time''---e.g., when the service is
+booted.
+@end table
+
+A service of this type is instantiated like this:
+
+@example
+(service guix-service-type
+         (guix-configuration
+           (build-accounts 5)
+           (use-substitutes? #f)))
+@end example
+
+The second argument to the @code{service} form is a value representing the
+parameters of this specific service instance.
+@xref{guix-configuration-type, @code{guix-configuration}}, for information
+about the @code{guix-configuration} data type.  When the value is omitted,
+the default value specified by @code{guix-service-type} is used:
+
+@example
+(service guix-service-type)
+@end example
+
+@var{guix-service-type} is quite simple because it extends other services
+but is not extensible itself.
+
+@c @subsubsubsection Extensible Service Types
+
+The service type for an @emph{extensible} service looks like this:
+
+@example
+(define udev-service-type
+  (service-type (name 'udev)
+                (extensions
+                 (list (service-extension shepherd-root-service-type
+                                          udev-shepherd-service)))
+
+                (compose concatenate)       ;concatenate the list of rules
+                (extend (lambda (config rules)
+                          (match config
+                            (($ <udev-configuration> udev initial-rules)
+                             (udev-configuration
+                              (udev udev)   ;the udev package to use
+                              (rules (append initial-rules rules)))))))))
+@end example
+
+This is the service type for the
+@uref{https://wiki.gentoo.org/wiki/Project:Eudev, eudev device management
+daemon}.  Compared to the previous example, in addition to an extension of
+@var{shepherd-root-service-type}, we see two new fields:
+
+@table @code
+@item compose
+This is the procedure to @dfn{compose} the list of extensions to services of
+this type.
+
+Services can extend the udev service by passing it lists of rules; we
+compose those extensions simply by concatenating them.
+
+@item extend
+This procedure defines how the value of the service is @dfn{extended} with
+the composition of the extensions.
+
+Udev extensions are composed into a list of rules, but the udev service
+value is itself a @code{<udev-configuration>} record.  So here, we extend
+that record by appending the list of rules it contains to the list of
+contributed rules.
+
+@item description
+This is a string giving an overview of the service type.  The string can
+contain Texinfo markup (@pxref{Overview,,, texinfo, GNU Texinfo}).  The
+@command{guix system search} command searches these strings and displays
+them (@pxref{Invoquer guix system}).
+@end table
+
+There can be only one instance of an extensible service type such as
+@var{udev-service-type}.  If there were more, the @code{service-extension}
+specifications would be ambiguous.
+
+Still here? The next section provides a reference of the programming
+interface for services.
+
+@node Référence de service
+@subsubsection Référence de service
+
+We have seen an overview of service types (@pxref{Types service et services}).  This section provides a reference on how to manipulate services
+and service types.  This interface is provided by the @code{(gnu services)}
+module.
+
+@deffn {Scheme Procedure} service @var{type} [@var{value}]
+Return a new service of @var{type}, a @code{<service-type>} object (see
+below.)  @var{value} can be any object; it represents the parameters of this
+particular service instance.
+
+When @var{value} is omitted, the default value specified by @var{type} is
+used; if @var{type} does not specify a default value, an error is raised.
+
+For instance, this:
+
+@example
+(service openssh-service-type)
+@end example
+
+@noindent
+is equivalent to this:
+
+@example
+(service openssh-service-type
+         (openssh-configuration))
+@end example
+
+In both cases the result is an instance of @code{openssh-service-type} with
+the default configuration.
+@end deffn
+
+@deffn {Scheme Procedure} service? @var{obj}
+Return true if @var{obj} is a service.
+@end deffn
+
+@deffn {Scheme Procedure} service-kind @var{service}
+Return the type of @var{service}---i.e., a @code{<service-type>} object.
+@end deffn
+
+@deffn {Scheme Procedure} service-value @var{service}
+Return the value associated with @var{service}.  It represents its
+parameters.
+@end deffn
+
+Here is an example of how a service is created and manipulated:
+
+@example
+(define s
+  (service nginx-service-type
+           (nginx-configuration
+            (nginx nginx)
+            (log-directory log-directory)
+            (run-directory run-directory)
+            (file config-file))))
+
+(service? s)
+@result{} #t
+
+(eq? (service-kind s) nginx-service-type)
+@result{} #t
+@end example
+
+The @code{modify-services} form provides a handy way to change the
+parameters of some of the services of a list such as @var{%base-services}
+(@pxref{Services de base, @code{%base-services}}).  It evaluates to a list of
+services.  Of course, you could always use standard list combinators such as
+@code{map} and @code{fold} to do that (@pxref{SRFI-1, List Library,, guile,
+GNU Guile Reference Manual}); @code{modify-services} simply provides a more
+concise form for this common pattern.
+
+@deffn {Scheme Syntax} modify-services @var{services} @
+  (@var{type} @var{variable} => @var{body}) @dots{}
+
+Modify the services listed in @var{services} according to the given
+clauses.  Each clause has the form:
+
+@example
+(@var{type} @var{variable} => @var{body})
+@end example
+
+where @var{type} is a service type---e.g., @code{guix-service-type}---and
+@var{variable} is an identifier that is bound within the @var{body} to the
+service parameters---e.g., a @code{guix-configuration} instance---of the
+original service of that @var{type}.
+
+The @var{body} should evaluate to the new service parameters, which will be
+used to configure the new service.  This new service will replace the
+original in the resulting list.  Because a service's service parameters are
+created using @code{define-record-type*}, you can write a succinct
+@var{body} that evaluates to the new service parameters by using the
+@code{inherit} feature that @code{define-record-type*} provides.
+
+@xref{Utiliser le système de configuration}, for example usage.
+
+@end deffn
+
+Next comes the programming interface for service types.  This is something
+you want to know when writing new service definitions, but not necessarily
+when simply looking for ways to customize your @code{operating-system}
+declaration.
+
+@deftp {Data Type} service-type
+@cindex service type
+This is the representation of a @dfn{service type} (@pxref{Types service et services}).
+
+@table @asis
+@item @code{name}
+This is a symbol, used only to simplify inspection and debugging.
+
+@item @code{extensions}
+A non-empty list of @code{<service-extension>} objects (see below).
+
+@item @code{compose} (default: @code{#f})
+If this is @code{#f}, then the service type denotes services that cannot be
+extended---i.e., services that do not receive ``values'' from other
+services.
+
+Otherwise, it must be a one-argument procedure.  The procedure is called by
+@code{fold-services} and is passed a list of values collected from
+extensions.  It may return any single value.
+
+@item @code{extend} (default: @code{#f})
+If this is @code{#f}, services of this type cannot be extended.
+
+Otherwise, it must be a two-argument procedure: @code{fold-services} calls
+it, passing it the initial value of the service as the first argument and
+the result of applying @code{compose} to the extension values as the second
+argument.  It must return a value that is a valid parameter value for the
+service instance.
+@end table
+
+@xref{Types service et services}, for examples.
+@end deftp
+
+@deffn {Scheme Procedure} service-extension @var{target-type} @
+                              @var{compute} Return a new extension for services of type
+@var{target-type}.  @var{compute} must be a one-argument procedure:
+@code{fold-services} calls it, passing it the value associated with the
+service that provides the extension; it must return a valid value for the
+target service.
+@end deffn
+
+@deffn {Scheme Procedure} service-extension? @var{obj}
+Return true if @var{obj} is a service extension.
+@end deffn
+
+Occasionally, you might want to simply extend an existing service.  This
+involves creating a new service type and specifying the extension of
+interest, which can be verbose; the @code{simple-service} procedure provides
+a shorthand for this.
+
+@deffn {Scheme Procedure} simple-service @var{name} @var{target} @var{value}
+Return a service that extends @var{target} with @var{value}.  This works by
+creating a singleton service type @var{name}, of which the returned service
+is an instance.
+
+For example, this extends mcron (@pxref{Scheduled Job Execution}) with an
+additional job:
+
+@example
+(simple-service 'my-mcron-job mcron-service-type
+                #~(job '(next-hour (3)) "guix gc -F 2G"))
+@end example
+@end deffn
+
+At the core of the service abstraction lies the @code{fold-services}
+procedure, which is responsible for ``compiling'' a list of services down to
+a single directory that contains everything needed to boot and run the
+system---the directory shown by the @command{guix system build} command
+(@pxref{Invoquer guix system}).  In essence, it propagates service
+extensions down the service graph, updating each node parameters on the way,
+until it reaches the root node.
+
+@deffn {Scheme Procedure} fold-services @var{services} @
+                            [#:target-type @var{system-service-type}] Fold @var{services} by propagating
+their extensions down to the root of type @var{target-type}; return the root
+service adjusted accordingly.
+@end deffn
+
+Lastly, the @code{(gnu services)} module also defines several essential
+service types, some of which are listed below.
+
+@defvr {Scheme Variable} system-service-type
+This is the root of the service graph.  It produces the system directory as
+returned by the @command{guix system build} command.
+@end defvr
+
+@defvr {Scheme Variable} boot-service-type
+The type of the ``boot service'', which produces the @dfn{boot script}.  The
+boot script is what the initial RAM disk runs when booting.
+@end defvr
+
+@defvr {Scheme Variable} etc-service-type
+The type of the @file{/etc} service.  This service is used to create files
+under @file{/etc} and can be extended by passing it name/file tuples such
+as:
+
+@example
+(list `("issue" ,(plain-file "issue" "Welcome!\n")))
+@end example
+
+In this example, the effect would be to add an @file{/etc/issue} file
+pointing to the given file.
+@end defvr
+
+@defvr {Scheme Variable} setuid-program-service-type
+Type for the ``setuid-program service''.  This service collects lists of
+executable file names, passed as gexps, and adds them to the set of
+setuid-root programs on the system (@pxref{Programmes setuid}).
+@end defvr
+
+@defvr {Scheme Variable} profile-service-type
+Type of the service that populates the @dfn{system profile}---i.e., the
+programs under @file{/run/current-system/profile}.  Other services can
+extend it by passing it lists of packages to add to the system profile.
+@end defvr

+@node Services Shepherd

+@cindex init system
+The @code{(gnu services shepherd)} module provides a way to define services
+managed by the GNU@tie{}Shepherd, which is the GuixSD initialization
+system---the first process that is started when the system boots, also known
+as PID@tie{}1 (@pxref{Introduction,,, shepherd, The GNU Shepherd Manual}).
+
+Services in the Shepherd can depend on each other.  For instance, the SSH
+daemon may need to be started after the syslog daemon has been started,
+which in turn can only happen once all the file systems have been mounted.
+The simple operating system defined earlier (@pxref{Utiliser le système de configuration}) results in a service graph like this:
+
+@image{images/shepherd-graph,,5in,Typical shepherd service graph.}
+
+You can actually generate such a graph for any operating system definition
+using the @command{guix system shepherd-graph} command
+(@pxref{system-shepherd-graph, @command{guix system shepherd-graph}}).
+
+The @var{%shepherd-root-service} is a service object representing
+PID@tie{}1, of type @var{shepherd-root-service-type}; it can be extended by
+passing it lists of @code{<shepherd-service>} objects.

+@item @code{requirements} (default: @code{'()})
+List of symbols denoting the Shepherd services this one depends on.

+Whether to restart the service when it stops, for instance when the
+underlying process dies.
+
+@item @code{start}
+@itemx @code{stop} (default: @code{#~(const #f)})
+The @code{start} and @code{stop} fields refer to the Shepherd's facilities

+@cindex searching for documentation
+@cindex Info, documentation format
+@cindex man pages
+@cindex manual pages
+In most cases packages installed with Guix come with documentation.  There
+are two main documentation formats: ``Info'', a browseable hypertext format
+used for GNU software, and ``manual pages'' (or ``man pages''), the linear
+documentation format traditionally found on Unix.  Info manuals are accessed
+with the @command{info} command or with Emacs, and man pages are accessed
+using @command{man}.
+
+You can look for documentation of software installed on your system by
+keyword.  For example, the following command searches for information about
+``TLS'' in Info manuals:
+
+@example
+$ info -k TLS
+"(emacs)Network Security" -- STARTTLS
+"(emacs)Network Security" -- TLS
+"(gnutls)Core TLS API" -- gnutls_certificate_set_verify_flags
+"(gnutls)Core TLS API" -- gnutls_certificate_set_verify_function
+@dots{}
+@end example
+
+@noindent
+The command below searches for the same keyword in man pages:
+
+@example
+$ man -k TLS
+SSL (7)              - OpenSSL SSL/TLS library
+certtool (1)         - GnuTLS certificate tool
+@dots {}
+@end example
+
+These searches are purely local to your computer so you have the guarantee
+that documentation you find corresponds to what you have actually installed,
+you can access it off-line, and your privacy is respected.
+
+Once you have these results, you can view the relevant documentation by
+running, say:
+
+@example
+$ info "(gnutls)Core TLS API"
+@end example
+
+@noindent
+or:
+
+@example
+$ man certtool
+@end example
+
+Info manuals contain sections and indices as well as hyperlinks like those
+found in Web pages.  The @command{info} reader (@pxref{Top, Info reader,,
+info-stnd, Stand-alone GNU Info}) and its Emacs counterpart (@pxref{Misc

+
+@node Installer les fichiers de débogage
+@section Installer les fichiers de débogage
+
+@cindex debugging files
+Program binaries, as produced by the GCC compilers for instance, are
+typically written in the ELF format, with a section containing
+@dfn{debugging information}.  Debugging information is what allows the
+debugger, GDB, to map binary code to source code; it is required to debug a
+compiled program in good conditions.
+
+Le problème avec les informations de débogage est qu'elles prennent pas mal
+de place sur le disque. Par exemple, les informations de débogage de la
+bibliothèque C de GNU prend plus de 60 Mo. Ainsi, en tant qu'utilisateur,
+garder toutes les informations de débogage de tous les programmes installés
+n'est souvent pas une possibilité. Cependant, l'économie d'espace ne devrait
+pas empêcher le débogage — en particulier, dans le système GNU, qui devrait
+faciliter pour ses utilisateurs l'exercice de leurs libertés
+(@pxref{Distribution GNU}).
+
+Thankfully, the GNU Binary Utilities (Binutils) and GDB provide a mechanism
+that allows users to get the best of both worlds: debugging information can
+be stripped from the binaries and stored in separate files.  GDB is then
+able to load debugging information from those files, when they are available
+(@pxref{Separate Debug Files,,, gdb, Debugging with GDB}).
+
+The GNU distribution takes advantage of this by storing debugging
+information in the @code{lib/debug} sub-directory of a separate package
+output unimaginatively called @code{debug} (@pxref{Des paquets avec plusieurs résultats}).  Users can choose to install the @code{debug} output of a package
+when they need it.  For instance, the following command installs the
+debugging information for the GNU C Library and for GNU Guile:
+
+@example
+guix package -i glibc:debug guile:debug
+@end example
+
+GDB must then be told to look for debug files in the user's profile, by
+setting the @code{debug-file-directory} variable (consider setting it from
+the @file{~/.gdbinit} file, @pxref{Startup,,, gdb, Debugging with GDB}):
+
+@example
+(gdb) set debug-file-directory ~/.guix-profile/lib/debug
+@end example
+
+From there on, GDB will pick up debugging information from the @code{.debug}
+files under @file{~/.guix-profile/lib/debug}.
+
+In addition, you will most likely want GDB to be able to show the source
+code being debugged.  To do that, you will have to unpack the source code of
+the package of interest (obtained with @code{guix build --source},
+@pxref{Invoquer guix build}), and to point GDB to that source directory
+using the @code{directory} command (@pxref{Source Path, @code{directory},,
+gdb, Debugging with GDB}).
+
+@c XXX: keep me up-to-date
+The @code{debug} output mechanism in Guix is implemented by the
+@code{gnu-build-system} (@pxref{Systèmes de construction}).  Currently, it is
+opt-in---debugging information is available only for the packages with
+definitions explicitly declaring a @code{debug} output.  This may be changed
+to opt-out in the future if our build farm servers can handle the load.  To
+check whether a package has a @code{debug} output, use @command{guix package
+--list-available} (@pxref{Invoquer guix package}).

+containing only security updates.)  The @command{guix lint} tool helps

+
+Guix suit une discipline de gestion de paquets fonctionnelle
+(@pxref{Introduction}), ce qui implique que lorsqu'un paquet change,
+@emph{tous les paquets qui en dépendent} doivent être reconstruits. Cela
+peut grandement ralentir le déploiement de corrections dans les paquets du
+cœur comme libc ou bash comme presque toute la distribution aurait besoin
+d'être reconstruite. Cela aide d'utiliser des binaires pré-construits
+(@pxref{Substituts}), mais le déploiement peut toujours prendre plus de
+temps de souhaité.
+
+@cindex grafts
+To address this, Guix implements @dfn{grafts}, a mechanism that allows for
+fast deployment of critical updates without the costs associated with a
+whole-distribution rebuild.  The idea is to rebuild only the package that
+needs to be patched, and then to ``graft'' it onto packages explicitly
+installed by the user and that were previously referring to the original
+package.  The cost of grafting is typically very low, and order of
+magnitudes lower than a full rebuild of the dependency chain.
+
+@cindex replacements of packages, for grafts
+For instance, suppose a security update needs to be applied to Bash.  Guix
+developers will provide a package definition for the ``fixed'' Bash, say
+@var{bash-fixed}, in the usual way (@pxref{Définition des paquets}).  Then, the
+original package definition is augmented with a @code{replacement} field
+pointing to the package containing the bug fix:
+
+@example
+(define bash
+  (package
+    (name "bash")
+    ;; @dots{}
+    (replacement bash-fixed)))
+@end example
+
+From there on, any package depending directly or indirectly on Bash---as
+reported by @command{guix gc --requisites} (@pxref{Invoquer guix gc})---that
+is installed is automatically ``rewritten'' to refer to @var{bash-fixed}
+instead of @var{bash}.  This grafting process takes time proportional to the
+size of the package, usually less than a minute for an ``average'' package
+on a recent machine.  Grafting is recursive: when an indirect dependency
+requires grafting, then grafting ``propagates'' up to the package that the
+user is installing.
+
+Currently, the length of the name and version of the graft and that of the
+package it replaces (@var{bash-fixed} and @var{bash} in the example above)
+must be equal.  This restriction mostly comes from the fact that grafting
+works by patching files, including binary files, directly.  Other
+restrictions may apply: for instance, when adding a graft to a package
+providing a shared library, the original shared library and its replacement
+must have the same @code{SONAME} and be binary-compatible.
+
+The @option{--no-grafts} command-line option allows you to forcefully avoid
+grafting (@pxref{Options de construction communes, @option{--no-grafts}}).  Thus, the
+command:
+
+@example
+guix build bash --no-grafts
+@end example
+
+@noindent
+returns the store file name of the original Bash, whereas:
+
+@example
+guix build bash
+@end example
+
+@noindent
+returns the store file name of the ``fixed'', replacement Bash.  This allows
+you to distinguish between the two variants of Bash.
+
+To verify which Bash your whole profile refers to, you can run
+(@pxref{Invoquer guix gc}):
+
+@example
+guix gc -R `readlink -f ~/.guix-profile` | grep bash
+@end example
+
+@noindent
+@dots{} and compare the store file names that you get with those above.
+Likewise for a complete GuixSD system generation:
+
+@example
+guix gc -R `guix system build my-config.scm` | grep bash
+@end example
+
+Lastly, to check which Bash running processes are using, you can use the
+@command{lsof} command:
+
+@example
+lsof | grep /gnu/store/.*bash
+@end example

+@node Modules de paquets
+@section Modules de paquets
+
+From a programming viewpoint, the package definitions of the GNU
+distribution are provided by Guile modules in the @code{(gnu packages
+@dots{})} name space@footnote{Note that packages under the @code{(gnu
+packages @dots{})} module name space are not necessarily ``GNU packages''.
+This module naming scheme follows the usual Guile module naming convention:
+@code{gnu} means that these modules are distributed as part of the GNU
+system, and @code{packages} identifies modules that define packages.}
+(@pxref{Modules, Guile modules,, guile, GNU Guile Reference Manual}).  For
+instance, the @code{(gnu packages emacs)} module exports a variable named
+@code{emacs}, which is bound to a @code{<package>} object (@pxref{Définition des paquets}).
+
+The @code{(gnu packages @dots{})} module name space is automatically scanned
+for packages by the command-line tools.  For instance, when running
+@code{guix package -i emacs}, all the @code{(gnu packages @dots{})} modules
+are scanned until one that exports a package object whose name is
+@code{emacs} is found.  This package search facility is implemented in the

+

+@cindex package module search path
+Users can store package definitions in modules with different names---e.g.,

+@xref{Modules and the File System,,, guile, GNU Guile Reference Manual}, for

+can invoke commands such as @command{guix package} and @command{guix build}
+with the @code{-e} option so that they know where to find the package.
+Better yet, they can use the @code{-L} option of these commands to make
+those modules visible (@pxref{Invoquer guix build, @code{--load-path}}), or
+define the @code{GUIX_PACKAGE_PATH} environment variable.  This environment
+variable makes it easy to extend or customize the distribution and is

+

+
+@cindex packages, creating
+The GNU distribution is nascent and may well lack some of your favorite
+packages.  This section describes how you can help make the distribution
+grow.  @xref{Contribuer}, for additional information on how you can help.
+
+Free software packages are usually distributed in the form of @dfn{source
+code tarballs}---typically @file{tar.gz} files that contain all the source
+files.  Adding a package to the distribution means essentially two things:
+adding a @dfn{recipe} that describes how to build the package, including a
+list of other packages required to build it, and adding @dfn{package
+metadata} along with that recipe, such as a description and licensing
+information.
+
+In Guix all this information is embodied in @dfn{package definitions}.
+Package definitions provide a high-level view of the package.  They are
+written using the syntax of the Scheme programming language; in fact, for
+each package we define a variable bound to the package definition, and
+export that variable from a module (@pxref{Modules de paquets}).  However,
+in-depth Scheme knowledge is @emph{not} a prerequisite for creating
+packages.  For more information on package definitions, @pxref{Définition des paquets}.
+
+Once a package definition is in place, stored in a file in the Guix source
+tree, it can be tested using the @command{guix build} command
+(@pxref{Invoquer guix build}).  For example, assuming the new package is
+called @code{gnew}, you may run this command from the Guix build tree
+(@pxref{Lancer Guix avant qu'il ne soit installé}):
+
+@example
+./pre-inst-env guix build gnew --keep-failed
+@end example
+
+Using @code{--keep-failed} makes it easier to debug build failures since it
+provides access to the failed build tree.  Another useful command-line
+option when debugging is @code{--log-file}, to access the build log.
+
+If the package is unknown to the @command{guix} command, it may be that the
+source file contains a syntax error, or lacks a @code{define-public} clause
+to export the package variable.  To figure it out, you may load the module
+from Guile to get more information about the actual error:
+
+@example
+./pre-inst-env guile -c '(use-modules (gnu packages gnew))'

+@c Adapted from http://www.gnu.org/philosophy/philosophy.html.
+@cindex free software
+The GNU operating system has been developed so that users can have freedom
+in their computing.  GNU is @dfn{free software}, meaning that users have the
+@url{http://www.gnu.org/philosophy/free-sw.html,four essential freedoms}: to
+run the program, to study and change the program in source code form, to
+redistribute exact copies, and to distribute modified versions.  Packages
+found in the GNU distribution provide only software that conveys these four
+freedoms.
+
+In addition, the GNU distribution follow the
+@url{http://www.gnu.org/distros/free-system-distribution-guidelines.html,free
+software distribution guidelines}.  Among other things, these guidelines
+reject non-free firmware, recommendations of non-free software, and discuss
+ways to deal with trademarks and patents.
+
+Some otherwise free upstream package sources contain a small and optional
+subset that violates the above guidelines, for instance because this subset
+is itself non-free code.  When that happens, the offending items are removed
+with appropriate patches or code snippets in the @code{origin} form of the
+package (@pxref{Définition des paquets}).  This way, @code{guix build --source}
+returns the ``freed'' source rather than the unmodified upstream source.
+
+
+@node Conventions de nommage
+@subsection Conventions de nommage
+
+@cindex package name
+A package has actually two names associated with it: First, there is the
+name of the @emph{Scheme variable}, the one following @code{define-public}.
+By this name, the package can be made known in the Scheme code, for instance
+as input to another package.  Second, there is the string in the @code{name}
+field of a package definition.  This name is used by package management
+commands such as @command{guix package} and @command{guix build}.
+
+Both are usually the same and correspond to the lowercase conversion of the
+project name chosen upstream, with underscores replaced with hyphens.  For
+instance, GNUnet is available as @code{gnunet}, and SDL_net as
+@code{sdl-net}.
+
+We do not add @code{lib} prefixes for library packages, unless these are
+already part of the official project name.  But @pxref{Modules python} and
+@ref{Modules perl} for special rules concerning modules for the Python and
+Perl languages.
+
+Font package names are handled differently, @pxref{Polices de caractères}.
+
+
+@node Numéros de version
+@subsection Numéros de version
+
+@cindex package version
+We usually package only the latest version of a given free software
+project.  But sometimes, for instance for incompatible library versions, two
+(or more) versions of the same package are needed.  These require different
+Scheme variable names.  We use the name as defined in @ref{Conventions de nommage}
+for the most recent version; previous versions use the same name, suffixed
+by @code{-} and the smallest prefix of the version number that may
+distinguish the two versions.
+
+The name inside the package definition is the same for all versions of a
+package and does not contain any version number.
+
+For instance, the versions 2.24.20 and 3.9.12 of GTK+ may be packaged as
+follows:
+
+@example
+(define-public gtk+
+  (package
+    (name "gtk+")
+    (version "3.9.12")
+    ...))
+(define-public gtk+-2
+  (package
+    (name "gtk+")
+    (version "2.24.20")
+    ...))
+@end example
+If we also wanted GTK+ 3.8.2, this would be packaged as
+@example
+(define-public gtk+-3.8
+  (package
+    (name "gtk+")
+    (version "3.8.2")
+    ...))
+@end example
+
+@c See <https://lists.gnu.org/archive/html/guix-devel/2016-01/msg00425.html>,
+@c for a discussion of what follows.
+@cindex version number, for VCS snapshots
+Occasionally, we package snapshots of upstream's version control system
+(VCS) instead of formal releases.  This should remain exceptional, because
+it is up to upstream developers to clarify what the stable release is.  Yet,
+it is sometimes necessary.  So, what should we put in the @code{version}
+field?
+
+Clearly, we need to make the commit identifier of the VCS snapshot visible
+in the version string, but we also need to make sure that the version string
+is monotonically increasing so that @command{guix package --upgrade} can
+determine which version is newer.  Since commit identifiers, notably with
+Git, are not monotonically increasing, we add a revision number that we
+increase each time we upgrade to a newer snapshot.  The resulting version
+string looks like this:
+
+@example
+2.0.11-3.cabba9e
+  ^    ^    ^
+  |    |    `-- upstream commit ID
+  |    |
+  |    `--- Guix package revision
+  |
+latest upstream version
+@end example
+
+It is a good idea to strip commit identifiers in the @code{version} field
+to, say, 7 digits.  It avoids an aesthetic annoyance (assuming aesthetics
+have a role to play here) as well as problems related to OS limits such as
+the maximum shebang length (127 bytes for the Linux kernel.)  It is best to
+use the full commit identifiers in @code{origin}s, though, to avoid
+ambiguities.  A typical package definition may look like this:
+
+@example
+(define my-package
+  (let ((commit "c3f29bc928d5900971f65965feaae59e1272a3f7")
+        (revision "1"))          ;Guix package revision
+    (package
+      (version (git-version "0.9" revision commit))
+      (source (origin
+                (method git-fetch)
+                (uri (git-reference
+                      (url "git://example.org/my-package.git")
+                      (commit commit)))
+                (sha256 (base32 "1mbikn@dots{}"))
+                (file-name (git-file-name name version))))

+@node Synopsis et descriptions
+@subsection Synopsis et descriptions
+
+@cindex package description
+@cindex package synopsis
+As we have seen before, each package in GNU@tie{}Guix includes a synopsis
+and a description (@pxref{Définition des paquets}).  Synopses and descriptions
+are important: They are what @command{guix package --search} searches, and a
+crucial piece of information to help users determine whether a given package
+suits their needs.  Consequently, packagers should pay attention to what
+goes into them.
+
+Synopses must start with a capital letter and must not end with a period.
+They must not start with ``a'' or ``the'', which usually does not bring
+anything; for instance, prefer ``File-frobbing tool'' over ``A tool that
+frobs files''.  The synopsis should say what the package is---e.g., ``Core
+GNU utilities (file, text, shell)''---or what it is used for---e.g., the
+synopsis for GNU@tie{}grep is ``Print lines matching a pattern''.
+
+Keep in mind that the synopsis must be meaningful for a very wide audience.
+For example, ``Manipulate alignments in the SAM format'' might make sense
+for a seasoned bioinformatics researcher, but might be fairly unhelpful or
+even misleading to a non-specialized audience.  It is a good idea to come up
+with a synopsis that gives an idea of the application domain of the
+package.  In this example, this might give something like ``Manipulate
+nucleotide sequence alignments'', which hopefully gives the user a better
+idea of whether this is what they are looking for.
+
+Descriptions should take between five and ten lines.  Use full sentences,
+and avoid using acronyms without first introducing them.  Please avoid
+marketing phrases such as ``world-leading'', ``industrial-strength'', and
+``next-generation'', and avoid superlatives like ``the most
+advanced''---they are not helpful to users looking for a package and may
+even sound suspicious.  Instead, try to be factual, mentioning use cases and
+features.
+
+@cindex Texinfo markup, in package descriptions
+Descriptions can include Texinfo markup, which is useful to introduce
+ornaments such as @code{@@code} or @code{@@dfn}, bullet lists, or hyperlinks
+(@pxref{Overview,,, texinfo, GNU Texinfo}).  However you should be careful
+when using some characters for example @samp{@@} and curly braces which are
+the basic special characters in Texinfo (@pxref{Special Characters,,,
+texinfo, GNU Texinfo}).  User interfaces such as @command{guix package
+--show} take care of rendering it appropriately.
+
+Synopses and descriptions are translated by volunteers
+@uref{http://translationproject.org/domain/guix-packages.html, at the
+Translation Project} so that as many users as possible can read them in
+their native language.  User interfaces search them and display them in the
+language specified by the current locale.
+
+To allow @command{xgettext} to extract them as translatable strings,
+synopses and descriptions @emph{must be literal strings}.  This means that
+you cannot use @code{string-append} or @code{format} to construct these
+strings:
+
+@lisp
+(package
+  ;; @dots{}
+  (synopsis "This is translatable")
+  (description (string-append "This is " "*not*" " translatable.")))
+@end lisp
+
+Translation is a lot of work so, as a packager, please pay even more
+attention to your synopses and descriptions as every change may entail
+additional work for translators.  In order to help them, it is possible to
+make recommendations or instructions visible to them by inserting special
+comments like this (@pxref{xgettext Invocation,,, gettext, GNU Gettext}):
+
+@example
+;; TRANSLATORS: "X11 resize-and-rotate" should not be translated.
+(description "ARandR is designed to provide a simple visual front end
+for the X11 resize-and-rotate (RandR) extension. @dots{}")

+@node Modules python
+@subsection Modules python
+
+@cindex python
+We currently package Python 2 and Python 3, under the Scheme variable names
+@code{python-2} and @code{python} as explained in @ref{Numéros de version}.  To
+avoid confusion and naming clashes with other programming languages, it
+seems desirable that the name of a package for a Python module contains the
+word @code{python}.
+
+Some modules are compatible with only one version of Python, others with
+both.  If the package Foo compiles only with Python 3, we name it
+@code{python-foo}; if it compiles only with Python 2, we name it
+@code{python2-foo}. If it is compatible with both versions, we create two
+packages with the corresponding names.
+
+If a project already contains the word @code{python}, we drop this; for
+instance, the module python-dateutil is packaged under the names
+@code{python-dateutil} and @code{python2-dateutil}.  If the project name
+starts with @code{py} (e.g. @code{pytz}), we keep it and prefix it as
+described above.
+
+@subsubsection Specifying Dependencies
+@cindex inputs, for Python packages
+
+Dependency information for Python packages is usually available in the
+package source tree, with varying degrees of accuracy: in the
+@file{setup.py} file, in @file{requirements.txt}, or in @file{tox.ini}.
+
+Your mission, when writing a recipe for a Python package, is to map these
+dependencies to the appropriate type of ``input'' (@pxref{Référence de paquet,
+inputs}).  Although the @code{pypi} importer normally does a good job
+(@pxref{Invoquer guix import}), you may want to check the following check
+list to determine which dependency goes where.
+
+@itemize
+
+@item
+We currently package Python 2 with @code{setuptools} and @code{pip}
+installed like Python 3.4 has per default.  Thus you don't need to specify
+either of these as an input.  @command{guix lint} will warn you if you do.
+
+@item
+Python dependencies required at run time go into @code{propagated-inputs}.
+They are typically defined with the @code{install_requires} keyword in
+@file{setup.py}, or in the @file{requirements.txt} file.
+
+@item
+Python packages required only at build time---e.g., those listed with the
+@code{setup_requires} keyword in @file{setup.py}---or only for
+testing---e.g., those in @code{tests_require}---go into
+@code{native-inputs}.  The rationale is that (1) they do not need to be
+propagated because they are not needed at run time, and (2) in a
+cross-compilation context, it's the ``native'' input that we'd want.
+
+Examples are the @code{pytest}, @code{mock}, and @code{nose} test
+frameworks.  Of course if any of these packages is also required at
+run-time, it needs to go to @code{propagated-inputs}.
+
+@item
+Anything that does not fall in the previous categories goes to
+@code{inputs}, for example programs or C libraries required for building
+Python packages containing C extensions.
+
+@item
+If a Python package has optional dependencies (@code{extras_require}), it is
+up to you to decide whether to add them or not, based on their
+usefulness/overhead ratio (@pxref{Envoyer des correctifs, @command{guix size}}).

+@node Modules perl
+@subsection Modules perl
+
+@cindex perl
+Perl programs standing for themselves are named as any other package, using
+the lowercase upstream name.  For Perl packages containing a single class,
+we use the lowercase class name, replace all occurrences of @code{::} by
+dashes and prepend the prefix @code{perl-}.  So the class @code{XML::Parser}
+becomes @code{perl-xml-parser}.  Modules containing several classes keep
+their lowercase upstream name and are also prepended by @code{perl-}.  Such
+modules tend to have the word @code{perl} somewhere in their name, which
+gets dropped in favor of the prefix.  For instance, @code{libwww-perl}
+becomes @code{perl-libwww}.
+
+
+@node Paquets java
+@subsection Paquets java
+
+@cindex java
+Java programs standing for themselves are named as any other package, using
+the lowercase upstream name.
+
+To avoid confusion and naming clashes with other programming languages, it
+is desirable that the name of a package for a Java package is prefixed with
+@code{java-}.  If a project already contains the word @code{java}, we drop
+this; for instance, the package @code{ngsjava} is packaged under the name
+@code{java-ngs}.
+
+For Java packages containing a single class or a small class hierarchy, we
+use the lowercase class name, replace all occurrences of @code{.} by dashes
+and prepend the prefix @code{java-}.  So the class @code{apache.commons.cli}
+becomes package @code{java-apache-commons-cli}.
+
+
+@node Polices de caractères
+@subsection Polices de caractères
+
+@cindex fonts
+For fonts that are in general not installed by a user for typesetting
+purposes, or that are distributed as part of a larger software package, we
+rely on the general packaging rules for software; for instance, this applies
+to the fonts delivered as part of the X.Org system or fonts that are part of
+TeX Live.
+
+To make it easier for a user to search for fonts, names for other packages
+containing only fonts are constructed as follows, independently of the
+upstream package name.
+
+The name of a package containing only one font family starts with
+@code{font-}; it is followed by the foundry name and a dash @code{-} if the
+foundry is known, and the font family name, in which spaces are replaced by
+dashes (and as usual, all upper case letters are transformed to lower
+case).  For example, the Gentium font family by SIL is packaged under the
+name @code{font-sil-gentium}.
+
+For a package containing several font families, the name of the collection
+is used in the place of the font family name.  For instance, the Liberation
+fonts consist of three families, Liberation Sans, Liberation Serif and
+Liberation Mono.  These could be packaged separately under the names
+@code{font-liberation-sans} and so on; but as they are distributed together
+under a common name, we prefer to package them together as
+@code{font-liberation}.
+
+In the case where several formats of the same font family or font collection
+are packaged separately, a short form of the format, prepended by a dash, is
+added to the package name.  We use @code{-ttf} for TrueType fonts,
+@code{-otf} for OpenType fonts and @code{-type1} for PostScript Type 1
+fonts.

+@node Bootstrapping
+@section Bootstrapping
+
+@c Adapted from the ELS 2013 paper.
+
+@cindex bootstrapping
+
+Bootstrapping in our context refers to how the distribution gets built
+``from nothing''.  Remember that the build environment of a derivation
+contains nothing but its declared inputs (@pxref{Introduction}).  So there's
+an obvious chicken-and-egg problem: how does the first package get built?
+How does the first compiler get compiled? Note that this is a question of
+interest only to the curious hacker, not to the regular user, so you can
+shamelessly skip this section if you consider yourself a ``regular user''.
+
+@cindex bootstrap binaries
+The GNU system is primarily made of C code, with libc at its core.  The GNU
+build system itself assumes the availability of a Bourne shell and
+command-line tools provided by GNU Coreutils, Awk, Findutils, `sed', and
+`grep'.  Furthermore, build programs---programs that run @code{./configure},
+@code{make}, etc.---are written in Guile Scheme (@pxref{Dérivations}).
+Consequently, to be able to build anything at all, from scratch, Guix relies
+on pre-built binaries of Guile, GCC, Binutils, libc, and the other packages
+mentioned above---the @dfn{bootstrap binaries}.
+
+These bootstrap binaries are ``taken for granted'', though we can also
+re-create them if needed (more on that later).
+
+@unnumberedsubsec Preparing to Use the Bootstrap Binaries
+
+@c As of Emacs 24.3, Info-mode displays the image, but since it's a
+@c large image, it's hard to scroll.  Oh well.
+@image{images/bootstrap-graph,6in,,Dependency graph of the early bootstrap
+derivations}
+
+The figure above shows the very beginning of the dependency graph of the
+distribution, corresponding to the package definitions of the @code{(gnu
+packages bootstrap)} module.  A similar figure can be generated with
+@command{guix graph} (@pxref{Invoquer guix graph}), along the lines of:
+
+@example
+guix graph -t derivation \
+  -e '(@@@@ (gnu packages bootstrap) %bootstrap-gcc)' \
+  | dot -Tps > t.ps
+@end example
+
+At this level of detail, things are slightly complex.  First, Guile itself
+consists of an ELF executable, along with many source and compiled Scheme
+files that are dynamically loaded when it runs.  This gets stored in the
+@file{guile-2.0.7.tar.xz} tarball shown in this graph.  This tarball is part
+of Guix's ``source'' distribution, and gets inserted into the store with
+@code{add-to-store} (@pxref{Le dépôt}).
+
+But how do we write a derivation that unpacks this tarball and adds it to
+the store? To solve this problem, the @code{guile-bootstrap-2.0.drv}
+derivation---the first one that gets built---uses @code{bash} as its
+builder, which runs @code{build-bootstrap-guile.sh}, which in turn calls
+@code{tar} to unpack the tarball.  Thus, @file{bash}, @file{tar}, @file{xz},
+and @file{mkdir} are statically-linked binaries, also part of the Guix
+source distribution, whose sole purpose is to allow the Guile tarball to be
+unpacked.
+
+Once @code{guile-bootstrap-2.0.drv} is built, we have a functioning Guile
+that can be used to run subsequent build programs.  Its first task is to
+download tarballs containing the other pre-built binaries---this is what the
+@code{.tar.xz.drv} derivations do.  Guix modules such as
+@code{ftp-client.scm} are used for this purpose.  The
+@code{module-import.drv} derivations import those modules in a directory in
+the store, using the original layout.  The @code{module-import-compiled.drv}
+derivations compile those modules, and write them in an output directory
+with the right layout.  This corresponds to the @code{#:modules} argument of
+@code{build-expression->derivation} (@pxref{Dérivations}).
+
+Finally, the various tarballs are unpacked by the derivations
+@code{gcc-bootstrap-0.drv}, @code{glibc-bootstrap-0.drv}, etc., at which
+point we have a working C tool chain.
+
+
+@unnumberedsubsec Building the Build Tools
+
+Bootstrapping is complete when we have a full tool chain that does not
+depend on the pre-built bootstrap tools discussed above.  This no-dependency
+requirement is verified by checking whether the files of the final tool
+chain contain references to the @file{/gnu/store} directories of the
+bootstrap inputs.  The process that leads to this ``final'' tool chain is
+described by the package definitions found in the @code{(gnu packages
+commencement)} module.
+
+The @command{guix graph} command allows us to ``zoom out'' compared to the
+graph above, by looking at the level of package objects instead of
+individual derivations---remember that a package may translate to several
+derivations, typically one derivation to download its source, one to build
+the Guile modules it needs, and one to actually build the package from
+source.  The command:
+
+@example
+guix graph -t bag \
+  -e '(@@@@ (gnu packages commencement)
+          glibc-final-with-bootstrap-bash)' | dot -Tps > t.ps
+@end example
+
+@noindent
+produces the dependency graph leading to the ``final'' C
+library@footnote{You may notice the @code{glibc-intermediate} label,
+suggesting that it is not @emph{quite} final, but as a good approximation,
+we will consider it final.}, depicted below.
+
+@image{images/bootstrap-packages,6in,,Dependency graph of the early
+packages}
+
+@c See <http://lists.gnu.org/archive/html/gnu-system-discuss/2012-10/msg00000.html>.
+The first tool that gets built with the bootstrap binaries is
+GNU@tie{}Make---noted @code{make-boot0} above---which is a prerequisite for
+all the following packages.  From there Findutils and Diffutils get built.
+
+Then come the first-stage Binutils and GCC, built as pseudo cross
+tools---i.e., with @code{--target} equal to @code{--host}.  They are used to
+build libc.  Thanks to this cross-build trick, this libc is guaranteed not
+to hold any reference to the initial tool chain.
+
+From there the final Binutils and GCC (not shown above) are built.  GCC uses
+@code{ld} from the final Binutils, and links programs against the just-built
+libc.  This tool chain is used to build the other packages used by Guix and
+by the GNU Build System: Guile, Bash, Coreutils, etc.
+
+And voilà! At this point we have the complete set of build tools that the
+GNU Build System expects.  These are in the @code{%final-inputs} variable of
+the @code{(gnu packages commencement)} module, and are implicitly used by
+any package that uses @code{gnu-build-system} (@pxref{Systèmes de construction,
+@code{gnu-build-system}}).
+
+
+@unnumberedsubsec Building the Bootstrap Binaries
+
+@cindex bootstrap binaries
+Because the final tool chain does not depend on the bootstrap binaries,
+those rarely need to be updated.  Nevertheless, it is useful to have an
+automated way to produce them, should an update occur, and this is what the
+@code{(gnu packages make-bootstrap)} module provides.
+
+The following command builds the tarballs containing the bootstrap binaries
+(Guile, Binutils, GCC, libc, and a tarball containing a mixture of Coreutils
+and other basic command-line tools):
+
+@example
+guix build bootstrap-tarballs
+@end example
+
+The generated tarballs are those that should be referred to in the
+@code{(gnu packages bootstrap)} module mentioned at the beginning of this
+section.
+
+Still here? Then perhaps by now you've started to wonder: when do we reach a
+fixed point? That is an interesting question! The answer is unknown, but if
+you would like to investigate further (and have significant computational
+and storage resources to do so), then let us know.
+
+@unnumberedsubsec Reducing the Set of Bootstrap Binaries
+
+Our bootstrap binaries currently include GCC, Guile, etc.  That's a lot of
+binary code! Why is that a problem? It's a problem because these big chunks
+of binary code are practically non-auditable, which makes it hard to
+establish what source code produced them.  Every unauditable binary also
+leaves us vulnerable to compiler backdoors as described by Ken Thompson in
+the 1984 paper @emph{Reflections on Trusting Trust}.
+
+This is mitigated by the fact that our bootstrap binaries were generated
+from an earlier Guix revision.  Nevertheless it lacks the level of
+transparency that we get in the rest of the package dependency graph, where
+Guix always gives us a source-to-binary mapping.  Thus, our goal is to
+reduce the set of bootstrap binaries to the bare minimum.
+
+The @uref{http://bootstrappable.org, Bootstrappable.org web site} lists
+on-going projects to do that.  One of these is about replacing the bootstrap
+GCC with a sequence of assemblers, interpreters, and compilers of increasing
+complexity, which could be built from source starting from a simple and
+auditable assembler.  Your help is welcome!
+
+
+@node Porter
+@section Porting to a New Platform
+
+As discussed above, the GNU distribution is self-contained, and
+self-containment is achieved by relying on pre-built ``bootstrap binaries''
+(@pxref{Bootstrapping}).  These binaries are specific to an operating system
+kernel, CPU architecture, and application binary interface (ABI).  Thus, to
+port the distribution to a platform that is not yet supported, one must
+build those bootstrap binaries, and update the @code{(gnu packages
+bootstrap)} module to use them on that platform.
+
+Fortunately, Guix can @emph{cross compile} those bootstrap binaries.  When
+everything goes well, and assuming the GNU tool chain supports the target
+platform, this can be as simple as running a command like this one:
+
+@example
+guix build --target=armv5tel-linux-gnueabi bootstrap-tarballs
+@end example
+
+For this to work, the @code{glibc-dynamic-linker} procedure in @code{(gnu
+packages bootstrap)} must be augmented to return the right file name for
+libc's dynamic linker on that platform; likewise,
+@code{system->linux-architecture} in @code{(gnu packages linux)} must be
+taught about the new platform.
+
+Once these are built, the @code{(gnu packages bootstrap)} module needs to be
+updated to refer to these binaries on the target platform.  That is, the
+hashes and URLs of the bootstrap tarballs for the new platform must be added
+alongside those of the currently supported platforms.  The bootstrap Guile
+tarball is treated specially: it is expected to be available locally, and
+@file{gnu/local.mk} has rules do download it for the supported
+architectures; a rule for the new platform must be added as well.
+
+In practice, there may be some complications.  First, it may be that the
+extended GNU triplet that specifies an ABI (like the @code{eabi} suffix
+above) is not recognized by all the GNU tools.  Typically, glibc recognizes
+some of these, whereas GCC uses an extra @code{--with-abi} configure flag
+(see @code{gcc.scm} for examples of how to handle this).  Second, some of
+the required packages could fail to build for that platform.  Lastly, the
+generated binaries could be broken for some reason.

+@chapter Remerciements
+
+Guix is based on the @uref{http://nixos.org/nix/, Nix package manager},
+which was designed and implemented by Eelco Dolstra, with contributions from
+other people (see the @file{nix/AUTHORS} file in Guix.)  Nix pioneered
+functional package management, and promoted unprecedented features, such as
+transactional package upgrades and rollbacks, per-user profiles, and
+referentially transparent build processes.  Without this work, Guix would
+not exist.
+
+The Nix-based software distributions, Nixpkgs and NixOS, have also been an
+inspiration for Guix.
+
+GNU@tie{}Guix itself is a collective work with contributions from a number
+of people.  See the @file{AUTHORS} file in Guix for more information on
+these fine people.  The @file{THANKS} file lists people who have helped by
+reporting bugs, taking care of the infrastructure, providing artwork and
+themes, making suggestions, and more---thank you!

+Subject: [PATCH] multiboot: bss_end_addr can be zero
+
+The multiboot spec (https://www.gnu.org/software/grub/manual/multiboot/),
+section 3.1.3, allows for bss_end_addr to be zero.
+
+A zero bss_end_addr signifies there is no .bss section.
