No, having nlink == 1 is not a bug and we should expect that behavior, the
same with the -ESTALE return for a directory.  This is true, at least, for
the linux client.

I'd like that as well, since there are a number of tests that just don't
make sense at all for NFS..  I'll figure out a way to do that.  We have
groups of tests right now, and NFS is one, but those seem to be tests that
should be run only by NFS.
