From 2e04ab7147948b51d4e437ca9ba910530ac2a788 Mon Sep 17 00:00:00 2001 From: Ludovic Courtès Date: Wed, 16 Jan 2019 11:18:34 +0100 Subject: services: avahi: Deprecate the 'avahi-service' procedure. * gnu/services/avahi.scm (): Export getters. Add default values. (avahi-service-type)[default-value]: New field. (avahi-service): Mark as deprecated. * gnu/services/desktop.scm (%desktop-services): Use the 'service' form instead of calling 'avahi-service'. * gnu/tests/base.scm (%avahi-os): Likewise. * doc/guix.texi (Base Services): Adjust example accordingly. (Networking Services): Update accordingly. --- doc/guix.texi | 71 ++++++++++++++++++++++++++++++++++++++++------------------- 1 file changed, 48 insertions(+), 23 deletions(-) (limited to 'doc') diff --git a/doc/guix.texi b/doc/guix.texi index 2039ff67cf..1cdf99dba7 100644 --- a/doc/guix.texi +++ b/doc/guix.texi @@ -10848,7 +10848,9 @@ system, you will want to append services to @var{%base-services}, like this: @example -(cons* (avahi-service) (lsh-service) %base-services) +(cons* (service avahi-service-type) + (service openssh-service-type) + %base-services) @end example @end defvr @@ -12709,31 +12711,54 @@ browsers, from accessing Facebook.
