One more question. Looking back at your NFS_START_SERVER script, I 
noticed that you are starting the NFS server "by hand" and not using 
your distro's scripts. I'm wondering if there if there is some aspect 
of the server configuration missing. Are you able to do a normal TCP 
or UDP mount of the server?
