I think what he means is a related problem like in
173923c41aee6533532024ece8cd0fb62b06d316 . With NFS we should really not do
become_root usually I think. As we don't know if the underlaying filesystem is
NFS or not, how about querying the quota without root first and fall back to
root if it fails? (Or the other way round?)
