I recently imported lite-2 for most of /sbin (that was relevant),
and did a cleanup of the source that it it compiles when the
WARNS=1 make(1) variable is set.

Whilst most things went hassle free, I had to spend a fair bit of
time hand merging fsck_ffs, and I also had to be careful in the
mount, umount and mount_* programs. As these are important programs
(with respect to users' information), I felt it important to ask
you to be on the lookout for any new problems.

Please send-pr any *new* problems with mount or fsck_ffs that you
notice from sources compiled from the sup that occurred today (or
later). However, I don't expect any (major) problems :-)
