Not wanting to hijack this (interesting) thread, but ..
I have to concur with Rick P - that's rather a odd requirement when each
FreeBSD install since at least 2.2 has come with root and toor (in that
order) in /etc/passwd. I don't use toor, but often enough read about
folks who do, and don't recall it ever being an issue with NFSv3. Are
you sure this is a problem that cannot be coded around in NFSv4?
