Well, NFS really doesn't go that deep. Keep in mind, when an NFS client
exec's a read or a write, that action is passed to the client OS, which then
exec's an RPC to the NFS server. The NFS server's nfsd gets the RPC, and
passes the request for a read/write off to the server's OS, which just handles
it as a normal read/write request to UFS (or ext2). That data then gets
passed back to the client via RPC again. It's all FM :)
