When Pass I selects no files at all for dumping (such as if you've
just finished a level 0 dump), Pass II selects every directory that
has subdirectories, and restore chokes on the resulting dump.  (Or
was it every directory that *doesn't* have subdirectories?  I haven't
seen this in a while, it was on a vax, but I seriously doubt that
Sun has fixed it).

Workaround:  create a file in each filesystem before starting.
