Puzzling over NFS4 [some progress]

[Petrus de Calguarium]

Although one doesn't need to reboot in Linux, only this solved the 'access 
denied' and 'MTAB does not exist' errors. I was now able to transfer files.

This does not work. I tried it on both computers (after the reboot and solving 
of the transmission problem) and sunrpc and nfsd remain mounted, even after 3 
or 4 iterations.

What doesn't give?
