We have a customer with industrial hardware which stores data (logs?)
via NFSv2.  So we might need to continue to support v2 indefinitely.

Possibly we could use a user-space-nfsd solution if/when v2 service is
removed from the kernel, but I would rather not.

Reverting the nfs-utils patches which remove v2 support is fairly easy. 
Reverting kernel patches that remove v2 support wouldn't be so easy in
the long term.

So I'd vote for not removing NFSv2 from the server.
