I tried pulling that >chain once before, and it's going to take some careful thought. I have no issue fixing that, if there's a better way. The only goal of the chain-pulling is to redirect the side protocols to UDP/TCP, much like the "mountproto=" option does. NLM, as you mention, is the tricky one, since it literally reaches into the NFS clnt struct and "borrows" the transport identifier by value. Tom.
