A better way to write that might be: when the "filesystem" is
not a filesystem.  The point with dump is that it only operates
on filesystems.  Although it allows you to use directory names,
it won't give you any joy unless they have a filesystem mounted
on them.  If you use device names, then you're sure that you're
actually dealing with a filesystem -- and you can also dump
filesystems that are not mounted.

Oh no!  Ability to understand dump's diagnostics is one of the
things that separates the experienced Unix hackers from the
newbies :-)
