I was thinking rather of just returning an EIO if people try. We know
that there are breakages w.r.t. certain operations as I pointed out in
my previous email.

I suppose it really boils down to the following:

Is there really a community of people out there relying on being able to
do ecryptfs over NFS today?
If so, what are they using it for, and are they going to care about
those breakages?

Cheers
