The proposal allows for a succinct up-front mechanism to ascertain the operations supported by the server in one round-trip. One could also figure out the minor versions supported by the server if the supported operations in the reply was zero. I don't see how one could achieve the same with NFS4ERR_NOTSUPP, maybe i'm missing something.. -- Robert.. _______________________________________________ nfsv4 mailing list nfsv4@ietf.org https://www1.ietf.org/mailman/listinfo/nfsv4
