    Hi,
    I think you are right but nevertheless customers often require to be =

compliant IPV6
    in their system even they don't use IPV6. Soon, IPV6 deployed, NFS =

will be
    one of the first applications used. Some others UNIX systems also =

have it,
    so interoperabity it would be good Linux have it.
    But that is true it will be interested to know when and who on the =

nfs lists is interested in
    to use it.

     After a first rejected solution and some new discussion on the =

NFSV4 mailing list,
Bull (Aur=E9lien) supplied a new document described the current =

implementation. This little design document is still here: =

http://nfsv4.bullopensource.org/doc/nfs_ipv6.php

 Any new remarks are welcome.

     May be some on this nfs mailing list have this kind of environmments.
     What  Bull can do is to run the robustness tests we are doing for =

IPV4 on IPV6.
