uhm, big problem there. It was auto-mounted, using the /net/machinename/exportname stuff; you don't get to mention any mount options that way..
Which, means if 2.2 ships with this bug, it's a NFS DOS attack.
Why do I consider it a DOS attack? you can kill off nfsd's with this bug, and the only way to recover is to reboot the machine...

that would be nice.. is it both server and client, or just one? and if one, which one?
