Discussion related to cado-nfs

[Emmanuel Thomé <Emmanuel.Thome@inria.fr>]

Many things have changed between 2.3.0 and 3.0.0-dev. Mixing and
matching clients and servers from different versions has never been a
goal (which I accept blame for. Presumably I could work to alleviate this
a little bit, but since we're not sending versions numbers in the
communication stream, there is probably not much that can be done).

The user id should not matter.

"3.0.0-dev from one year ago" is not a thing, sorry. There might be
something fishy going on, but could you please try with a more recent
version ? (ideally with python3 for the client, since we've deprecated
python2 now)

out of curiosity, what is your filesystem ?
