Yes, see my last sentence above. :)

Err, well, when we run fsck on an existing partition, we shouldn't say
'fsck /dev/ad0s1a', we should use 'fsck_ffs /dev/ad0s1a'. Does that make sense
now? We shouldn't be calling fsck_4.2bsd for these filesystems because they
aren't 4.2BSD file systems per se, they are FFS, possibly with softupdates.

With devfs /dev should have all existing disks and partitions. At least if you
open the device it will create it for you if it is valid. We should always
use the devfs /dev if it is present and fall back to /mnt/dev from the CD if
it is not.
