Well, again it's me confusing stuff.
With MOUNTD_TCP=no I thought I could prevent the clients from mounting
the server with NFS over tcp... which is something I already have,
because current RH kernels don't have NFS server support over TCP
enabled in the kernel.

Thanks for your time.

Greetings,
    Marc
