Speaking of which, what's missing now? I see text-based mounts, client-side
IPv6 RPC and server-side transport switch (of which the first two are already
in mainline, and the last seems to be on its way) -- my impression was that
these are all important building blocks. I guess nfs-utils will also need
some patching, and an IPv6 transport will be needed for plugging into the
server side transport switch, but after that?

The client very much needs server support to be present in order to
function correctly. NFSv2/v3 NLM locking callbacks and NFSv4 delegations
will fail to work without server side IPv6 support.

We also need to convert rpc.statd and the kernel rpc.statd upcall.

Finally, we need to convert rpc.gssd/rpc.svcgssd and rpc.idmapd to work
with IPv6.

Cheers
Trond
