I doubt that this would solve the problem since in the scenario I had, the 
client already had mounted a directory from a server. Then on the server the 
minor ids of exported NFS volumes changed and then the client did see 
the "wrong" contents in the "right" NFS share mounted from the server. The 
problem is that NFS relies on major, minor numbers in its protocol, I think. 
So UUIDs could only help  in an initial mount but not later.
