Secure floppy filesyetms (was Re: interesting feature on AMIX..)

[Wolfram Schmidt]

Quote from the Ultrix 3.1 mount manual page (whithout permission, of course):

         General users can only mount file systems with certain res-
         trictions.  For example, the user, other than the superuser,
         performing the mount must own the directory directory.
         Furthermore, no users other than the superuser can execute
         setuid or setgid programs on the mounted file systems.  In
         addition, users other than the superuser cannot access block
         or special character devices such as rra0g on the mounted
         file systems.

If it works, that's what we need!
