You could say that the bug was that rpcbind starts before the NFS server has registered... but as the NFS server *cannot* register before rpcbind starts, that would be a little harsh. RPC_PROGNOTREGISTERED is a very close analogy to ECONNREFUSED. They both say "The server process isn't listening (yet)". One at the TCP/IP level, one at the SUNRPC level. If we started all daemons before enabling the network interface, and if we could register all RPC services before rpcbind responds to external requests, then these windows could be closed. Unfortunately our forefathers didn't have that foresight. Thanks, NeilBrown
