Tell them to RTFM.

I can't imagine why they would say that. It is a trivial matter to do
what you ask. Tell them to take a look at "exports","exportfs" and
"mount" in the man pages. That might refresh their memory.

You need to explicity state (in /etc/exports) that a certain machine
can have superuser priveleges on a remote filesystem. The one hole I
see is if you decide to be mean and...

1) make a new user with a uid and gid which are the same as one on the
	Sun4 
2) delete all their files

You wouldn't do that would you?
