Hi,
I'm trying to install guix (inside qemu) with "/" on lvm on luks on
sda2. sda1 contains the efi partition:
NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINTS
fd0 2:0 1 4K 0 disk
sda 8:0 0 30G 0 disk
├─sda1 8:1 0 600M 0 part /mnt/efi
└─sda2 8:2 0 29.4G 0 part
└─lukspart 253:0 0 29.4G 0 crypt
└─lvmSystem-volRoot 253:1 0 29.4G 0 lvm /tmp
/mnt
sr0 11:0 1 813.9M 0 rom
sr1 11:1 1 1024M 0 rom
The installation finishes with no problem. However on reboot grub errors
out:
error: disk

Looks like it cannot load the modules luks / luks2. Is it looking for
those on the root partition? That lvmid belongs to my root partition.
Well, that's still encrypted. I attached the grub.cfg created by guix
system init.
I don't know how this chicken-egg problem is generally solved by grub.
On my day-to-day system I have a similar setup (root on lvm on luks),
but I don't know, why/how this works. I do have a 1M grub partition,
though I believe I just followed a bad guide and it is only used on
bios+gpt systems.
Is there something wrong with my config.scm, or is this a guix bug?
