Ignoring the setuid would certainly be orders of magnitude simpler to
implement.  Off hand I can't think of any reason a user would need files
that were setuid to himself, since he is already himself.   ;^)

He can't create files that are setuid to anyone else unless he is root, and
no one else is depending on files that are setuid to himself, because his
filesystem is temporary.

Can anyone think of a reason why setuid bits need to be securely enabled (as
opposed to being ignored) on a temporary filesystem like a floppy disk?
