Not really hopelessly broken. What of course doesn't work is mounting /usr via nfs in combination with NM since NM resides on /usr. Other than that, NFS volumes are mounted via the usual if-up.d hooks you mentioned above. The thing that broke here, is that Andrew added a ADDRFAM check to the mountnfs hook which clashes with NM uses of ADDRFAM.
