nfs server fails to start

[Bill Rees]

Ok,
    I'm clueless.  I had nfs sharing and mounting working when running 
fc2 but now that fc4 is the os, I'm getting "FATAL: unable to load 
sunrpc" messages which is how starting up nfs fails for me.  The daemon 
starts but the mapper doesn't.  And while I'm at it, trying to build a 
kernel with this module built in is non-trivial for me as well.

    So the big question is, what do I do to be able to share a directory 
from one machine to the whole world and then mount it from another 
machine (without the permission denied messages) without specifiying a 
particular user or machine?  In my situation, I've got diskless clients 
that need to mount from a well known server, but the clients have random 
names.

    Help?  Please?
