I've been using luks + dm-crypt (http://wiki.archlinux.org/index.php/System_Encryption_with_LUKS_for_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. -Brendan Long
