I've been using luks + dm-crypt
to encrypt / and /home. Both are using ext4. For some reason, mounting /
always works, but sometimes I get an error that my /home partition
"doesn't describe a valid ext2 filesystem". If I reboot, it usually
works (I would guess it fails around 50% of the time). It's listed in
/etc/fstab as ext4. Is there anywhere else I need to put the filesystem
type? /etc/crypttab didn't seem to have a section for filesystem type.
