nolockd
Do not forward fcntl(2) locks over the wire. All locks
will be local and not seen by the server and likewise not
seen by other NFS clients. This removes the need to run
the rpcbind(8) service and the rpc.statd(8) and
rpc.lockd(8) servers on the client. Note that this
option will only be honored when performing the initial
mount, it will be silently ignored if used while updating
the mount options.
