I've been seeing this too, on a Debian system.  I should have realized
it was up to me to report this and/or fix it.  :-,

So, what's the deal, guys?

The deal is that several people have made changes to the NFS mount
structures.

One such change is to allow NFSv2/v3 to use RPCSEC_GSS (BTW: we're
*still* waiting to hear from this list about including the RPCSEC_GSS +
NFSv4 support daemons into the official nfs-utils) the other is a change
requested by the SELinux peoples to allow them to pass security context
information into the kernel as part of the mount process.

Cheers,
  Trond

I, for one, would like to see these daemons put in nfs-utils (sorry for not
voicing an opinion earlier).

Well, I'd be glad to look at patches for inclusion in Debian's
nfs-utils.  I'd probably put them in CVS but on a branch.

The first four patches here:

  http://www.citi.umich.edu/projects/nfsv4/linux/nfs-utils-patches/1.0.6-8/

are the ones we'd like to get into nfs-utils.  (Actually, Neil applied
the first already, so it's just 2, 3, and 4.)

The original complaint of course is about mount, for which util-linux
needs patches:

  http://www.citi.umich.edu/projects/nfsv4/linux/util-linux-patches/2.11z-3/

You might want to take a look at the  nfs-utils on my people page
(people.redhat.com/steved/nfs/nfsv4). Its got both the rpc.idmapd
and rpc.gssed integrated. The util-linux on the same page also
had the v4 mount hooks needed as well....

I dont know what the pitfalls would be, but if there arent too many, 
my vote is "in". As soon as fedora has v4 enabled nfs-utils, i intend 
to try it with rpcsec_gss.

BTW I just found that the above mentioned kernel message will not go
away entirely unless you patch it out of your kernel.  mount will try
to mount with the highest available kernel mount version by default
(usually 4 for all but very old kernels), but when that fails for some
reason, it will fall back to kernel mount version 3.
