Would your server, by chance, not be compiled with NFSv3 support?  If
not, I would encourage you to do so.  It is also possible that the FAI
client is compiled only with NFSv2 support, in which case I would see
the problem.  Check the kernel config options in both kernels to make
sure they're the same or at least that both are capable of the same
version (looks like 2's a winner for you).

You could propose yet another variable for the fai.conf file: NFS_SVER.
Or, a more dynamic way would include some logic to test the server's
available versions, the client kernel's existing versions, and choose
the best match during the make-fai-nfsroot tasks.

Anyway, back to the grind.
