Oh, right. Hm. I don't actually understand exactly what the obstacles are to maintaining it reliably, though intuitively it's easy to believe that it's impossible. Is the problem just clients that die and never come back, or are there inherent race coditions updating the rmtab on unmount? > nfsd.export is needed because once auth.unix.ip and nfsd.fh have > provided their information - it combines the two together to get > export options. I don't see why this *has* to be done on demand, though, unless the export table is extremely large and only sparsely used. I might be missing something. > That leaves nfs4.nametoid and nfs4.idtoname.
