From e34ae75dc14acb97f661a2787a3c626d7ce65b24 Mon Sep 17 00:00:00 2001 From: Ludovic Courtès Date: Thu, 15 Nov 2018 18:39:18 +0100 Subject: linux-initrd: Return file-like objects instead of monadic values. This is an incompatible change visible to users via the 'initrd' field of 'operating-system'. However, assuming the user's 'initrd' value tail-calls to 'raw-initrd' or 'base-initrd', the switch to non-monadic style is invisible. * gnu/system/linux-initrd.scm (expression->initrd): Use 'computed-file' instead of 'gexp->derivation'. (raw-initrd, base-initrd): Adjust docstring to mention non-monadic return. * gnu/system/vm.scm (expression->derivation-in-linux-vm): Adjust accordingly. * gnu/system.scm (operating-system-directory-base-entries) (operating-system-initrd-file) (operating-system-boot-parameters): Adjust accordingly. * doc/guix.texi (operating-system Reference) (Initial RAM Disk): Update. --- doc/guix.texi | 14 +++++++------- 1 file changed, 7 insertions(+), 7 deletions(-) (limited to 'doc') diff --git a/doc/guix.texi b/doc/guix.texi index a9c6e975a7..53ff744ea7 100644 --- a/doc/guix.texi +++ b/doc/guix.texi @@ -9860,7 +9860,7 @@ The list of Linux kernel modules that need to be available in the initial RAM disk. @xref{Initial RAM Disk}. @item @code{initrd} (default: @code{base-initrd}) -A monadic procedure that returns an initial RAM disk for the Linux +A procedure that returns an initial RAM disk for the Linux kernel.
