   Not quite.  The name that is matched is the name that the requesting
   machine sends the server.  It's strange to do the security check this
   way because a requesting machine could lie about its name.

   You have to start /etc/mountd with the -i option to make it verify
   the IP address as described above (which is not the DEC default).

not only is it not supported, but on an DECstation 3100 with Ultrix 3.1,
we get...

# /etc/mountd -i
# ps -augx | grep mountd
root     28387  0.0  0.3   40   32 p0 S     0:00 grep mountd
# /etc/mountd
# !ps
ps -augx | grep mountd
root     28389  0.0  1.3  192  156 p0 S     0:00 /etc/mountd
root     28391  0.0  0.3   40   32 p0 S     0:00 grep mountd
#

i.e. /etc/mountd doesn't appear to work.

and yes, I'd file an SPR, but I *still* don't know how to do this
electroniclly (or at all, actually).
