From: Jeff Layton <jlayton@xxxxxxxxxx> I occasionally see people that expect valid info when running showmount against a server that may export some or all filesystems via NFSv4. Let's make it clear that it only works by talking to the remote MNT service, and that that may not be available from a v4-only server.
