Right now, with MSDOS floppies, with no userids, the user owning the
mount point gets his userid applied to the entire disk. This allows me to
mount my floppies, etc. on mount points that I own, and I own all
the resulting files. I think you want the same thing as an option for
UFS mounts.

I don't think this is entirely true, and isn't a useful or enforceable
restriction.

Only with SYSV chown semantics that allow non-root to make files not
owned by them.

This is solved by having the "nouid" or somesuch thing add to /etc/fstab
by the admin who knows which ones should be trusted. Linux provides "user"
to get the behaviour that we get for free.

See what AT&T did with RFS. This may be a negative example (i.e. don't do
this).
