Hi,

I have several times over tried to install to a LUKS-partition with
btrfs and failed but last time I almost had success. guix init command
complained that the bios_grub flag wasn't set after many hours of
compiling packages and therefore didn't install grub at first. I
checked the partition with "cryptsetup luksUUID /dev/sda1" before
rerunning guix init and it gives me the luksUUID so the partition
seemed intact up to that point. However, after setting the bios_grub
flag and rerunning guix init, the installation is successful but
afterwards the cryptsetup luksUUID command says that the partition is
not a valid luks device, so it seems like the GRUB installation part
is what ruins the partition.

Interesting. Did you reserve some sectors before the first partition? Or
do you have the root partition marked as "bios_grub", which is what
seemingly wiped the LUKS headers here?
