From 3b09332adf7ce8e976a4d117a62c586a53af04aa Mon Sep 17 00:00:00 2001 From: Ludovic Courtès Date: Sat, 29 Nov 2014 14:40:26 +0100 Subject: system: Add a 'needed-for-boot?' field to 'mapped-device'. * gnu/system/file-systems.scm ()[needed-for-boot?]: New field. * gnu/system.scm (operating-system-user-mapped-devices, operating-system-boot-mapped-devices): Use it instead of trying to guess. Guessing doesn't work when one refers to a partition using its label, for instance. * doc/guix.texi (Mapped Devices): Document 'needed-for-boot?'. --- gnu/system.scm | 17 ++++------------- gnu/system/file-systems.scm | 5 ++++- 2 files changed, 8 insertions(+), 14 deletions(-) (limited to 'gnu') diff --git a/gnu/system.scm b/gnu/system.scm index e1ed1a2f19..731f9de55f 100644 --- a/gnu/system.scm +++ b/gnu/system.scm @@ -250,23 +250,14 @@ as 'needed-for-boot'."
