(Ludo suggested to report this as a bug, so this issue won’t get lost.)
While booting, GRUB prints this error:
error: file
‘/gnu/store/rz…-linux-libre-3.17.3/bzImage’ not found.
which is not surprising since the store is encrypted.
I’ve tried putting these lines after the “setparams” line in the GRUB
config (by hitting the ‘e’ key):
insmod luks
cryptomount hd0,gpt3
set root=crypto0
After pressing the ‘F10’ key, I get a password prompt. And after that, a
bunch of warnings about ‘/dev/mapper/main’:
ext2fs_check_if_mount: Can’t check if filesystem is mounted due to
missing mtab file while determining whether /dev/mapper/main is mounted.
fsck.ext3: No such file or directory while trying to open
/dev/mapper/main
Possibly non-existent device?
‘fsck.ext3’ exited with code 8 on /dev/mapper/main; spawning REPL
