Unfortunately, no.  So I'm unable to try and reproduce the
exact problem that you're seeing.

Wheh!  OK, that's good to hear.

Unfortunately, yes :-(  It certainly sounds like something in
the nfs-server is doing the wrong thing when resolving mounts
in this situation.

I'm sorry that you're seeing this problem, Rodrigo - and I
don't think that I will have the ability to dig into this
problem anytime soon.  If you have any interest in working on
resolving it, I'd be happy to hear whatever else you can
discover about the problem.
