But we might decide we want separate processes for servicing MOUNT requests and export upcalls anyway. In which case, call one rpc.mountd, the other nfsd-cache-helper, don't bother running "rpc.mountd" in the v4-only case, and, yay, we never have to answer the "why do I still have to run rpc.mountd?" question again. I dunno. --b.
