The problem would manifest itself by this cryptic GRUB error: "error: attempt to read or write outside of disk `proc'" The solution was to have a separate *and* standalone boot partition. The separate part is easy; just create a new partition and mount it as /boot in your config file system definitions. The second "standalone" part is not taken care by Guix System yet; with the help of Tobias I devised the following script that copies the minimum (init RAM disks and kernel images) to /boot and strips the prefixes on these paths, if any (I use Btrfs subvolumes): --8<---------------cut here---------------start------------->8--- #!/usr/bin/env bash set -e # Copy kernel and initrd images to /boot images=$(grep -E '^ (linux|initrd) ' /boot/grub/grub.cfg \ | awk '{ print $2 }' | sed 's|.*/gnu|/gnu|g' | sort | uniq) for image in $images; do mkdir -p /boot$(dirname $image) if [ ! -e /boot$image ] || ! cmp -s $image /boot$image; then echo copying cp $image to /boot$image... > /dev/error cp $image /boot$image fi done # Adjust /boot/grub/grub.cfg. sed -E -e 's/.*search.*--set.*//' \ -e 's/^insmod luks.*//' \ -e 's/^cryptomount.*//' \ -e 's,^( (linux|initrd) )[^ ]*(/gnu/[^ ]* ?),\1\3,' \ -i.bak /boot/grub/grub.cfg --8<---------------cut here---------------end--------------->8--- It's on my TODO to address this properly in Guix when I'll have the bandwidth. I hope that helps, Thanks! Maxim
