[K12OSN] NFS Error

With NFS exports, unlike Windows shares, any directory beneath exported 
directory can be mounted on another machine.  IOW, if /opt/ltsp is exported, the 
client machine can mount, say, /opt/ltsp/i386 under whatever mountpoint he 
chooses.  Or the client could mount /opt/ltsp/i386/etc under the desired 
mountpoint.  You are not limited to only mounting at the directory exported.

That aside, try booting a fat client on your thin client network and see if you 
can manually mount what the server is exporting.  If you can, then at least you 
know NFS is working correctly.  If you can't, then at least you've narrowed the 
scope of the problem.
