Ah, you're most likely right on this! It didn't occur me before... but: j@uriah 598% /sbin/dump 0f /dev/null /usr/src DUMP: Date of this level 0 dump: Sat Oct 12 13:17:54 1996 DUMP: Date of last level 0 dump: the epoch DUMP: Dumping /usr/src to /dev/null DUMP: bad sblock magic number DUMP: The ENTIRE dump is aborted.
