I think I was a bit hasty in saying this worked. Another possible reason
is guix system init doesn't try to do anything with these directories
anyway so maybe the fact that these subvolumes are "supported" is a
false positive.

I've tried an even simpler layout: no subvolumes, just

mount -t btrfs -o defaults,compress=lzo,ssd,noatime LABEL=btrfs /mnt
mount -o X-mount.mkdir /dev/nvme0n1p1 /mnt/boot/efi

However, I'm experiencing the same decryption error with this setup.
