From 6412e58a6843aaec573a65bacf58308ac4ee9035 Mon Sep 17 00:00:00 2001 From: Ludovic Courtès Date: Tue, 9 Dec 2014 11:06:22 +0100 Subject: system: Don't make /boot/grub/grub.cfg a symlink to the store. This would not work when /boot is a separate partition, as reported by Nikita Karetnikov in . This fixes a regression introduced in 39d1f82. * gnu/build/install.scm (install-grub): Copy GRUB.CFG instead of symlinking it, as was the case before 39d1f82. * gnu/build/vm.scm (register-grub.cfg-root): Add 'grub.cfg' parameter. Make it a permanent GC root instead of an indirect GC root. (initialize-hard-disk): Adjust accordingly. * guix/scripts/system.scm (install-grub*): Replace use of 'add-indirect-root' by the addition of a permanent GC root in %GC-ROOTS-DIRECTORY. --- gnu/build/install.scm | 13 ++++++++----- gnu/build/vm.scm | 19 ++++++------------- 2 files changed, 14 insertions(+), 18 deletions(-) (limited to 'gnu') diff --git a/gnu/build/install.scm b/gnu/build/install.scm index 111b79ee59..aa901f6971 100644 --- a/gnu/build/install.scm +++ b/gnu/build/install.scm @@ -36,15 +36,18 @@ (define-module (gnu build install) (define* (install-grub grub.cfg device mount-point) "Install GRUB with GRUB.CFG on DEVICE, which is assumed to be mounted on -MOUNT-POINT.
