In my (fairly considerable) experience with Linux's NFS systems, it is
probably easier (and more reliable) to get the BSD machine to accept
non-root NFS requests.  IMHO this restriction is silly anyway, as there
are so many single-user PC-type machines which allow anything to grab
ports below the 1024 mark with impunity that the root restrictions are all
but useless now anyway.

The other thing to check is your exports file.  Most exports file parsers
I've looked at (Linux's and IIRC BSD's too) are broken in a number of
respects (mine is, too, before you ask ;-).  You are best off making sure
that each machine is explicitly named in the exports file, with the
correct options on each, and not relying on any wildcards in addresses.

IIRC, adding a '-P' to the commandline of the nfsd should make it ignore
root ports, but you'd better check the man page.
