SUMMARY: bad backups with Solaris/Disksuite/Auspexes/Budtool

the consensus of the few responses was that sunos "restore"
was not guaranteed to accept a dump made with "ufsdump".

we were in fact able to run "ufsrestore" successfully on another
solaris machine reading the tape drive through the auspex,
so the backups were being written correctly (which was our
major worry).

note that auspexes have built-in support for filesystems bigger
than the size of the solaris disk being backed up (12GB).
