NFS: "[no]resvport" mount option changes mountd client too 



If the admin has specified the "noresvport" option for an NFS mount
point, the kernel's NFS client uses an unprivileged source port for
the main NFS transport.  The kernel's mountd client should use an
unprivileged port in this case as well.
