There is something fishy about 'dump -L'.  When I dump a busy mail
server and then restore the dumps, I often get the message lile

./CommuniGate/Domains/mail.tomsk.ru/mptdkfe.macnt/account.info: (inode 7206930) not found on tape

However, restoring this filesystems has always worked in general, with
a few file lost like shown above.

If you have SU+J, you cannot use -L at all, 'dump -L' (or mksnap_ffs)
will complain.
