Apart from the error, this is the only place that anything looks odd.
When / is exported a v4root, there doesn't need to be a uuid=.
It is the same uuid as for /home.
When I experiment I don't get a uuid= for /.
I don't know that this would cause a problem, but maybe it does.
Two extra pieces of debugging info that might be useful:
1/ Get a network trace for port 2049 traffic between client and server
with tcpdump.
Be sure to use "-s 0" and provide the binary packet capture - compress
it and attach it to the email.
2/ Before attempting the mount, and after restarting rpc.mountd on the
server and running "exportfs -f", run "strace -s 1000 -o /tmp/somefile -p ..." on the
rpc.mountd process, then try the mount, then kill strace.
Then provide /tmp/somefile.
