Solaris does achieve 'NFS-mounts from the local Server' via a special
"Filesystem", the so called "Loopback Filesystem (lsof)". If you give me
a few days I can look what the lsof does. I expect, that it does
something like a "redirect" or a "special hard-link" without increasing
the Link-Counter.
So what I think you have to do is to write a new filesystem with a new
mount-command (mount.lsof), so that you can do a mount -F lsof
localhost:/export/home/bla /home/bla.
In my opinion this isn't too easy to handle. By the way: I would never
let inexperienced people work on the Fileserver; even I wouldn't let any
person except Administrators work on the fileserver.
