Subject: [PATCH nfs-utils] Give useful error if mount.nfs not installed setuid.


If mount.nfs is not installed setuid, an attempt to perform a "user"
or "users" mount will fail with a fairly obscure error message,
typically about getting "permission denied" from the server.

This patch gives a more helpful message in that case.
