stub lockd. This implements just the protocol, but does not interact with the kernel. It says "Yes!" to all requests. This is useful if you have people using tools that do locking for no reason (eg: some PC NFS systems running some Microsoft products) and will happily report they couldn't lock the file and merrily proceed anyway. Running this will not change the reliability of sharing files, it'll just keep it out of everybody's face.
