Ummm.... let's back up a bit.  Nevermind I haven't a clue what stat()
and st_dev are.  If a "filesystem is not mounted", how could there be
any root (/) dir?  If the dir foo has not been mounted how can one put
a file into a dir that doesn't exist ...in a filesystem that hasn't
been mounted?  Is there some editor ....cat, vi, emacs... that will
create a filesystem and dir if a nonexistent dir/file is specified and
doesn't exist?
