Given the discussion on the linux-nfs list, I actually doubt this change
will be reverted. I can see that this could potentially be desired
behavior, but in some circumstances, it's catastrophic. For example, in
our environment we have kerberized nfs home directories. If a user runs
something in screen and logs out, they can't ever log back in to renew
credentials if they expire. Also, if they're logged into a graphical
workstation and credentials expire while the screensaver is running, it
can't ever pop up the dialog prompting for password - ouch!

I'm testing the patch provided by John Hughes on the Debian bug and it
seems to work really well. The only catch is that you have to edit the
gssd.conf upstart script directly, since it doesn't read RPCGSSD_OPTS
from the nfs-utils defaults file any more. (bug #564043)

I'm rolling this out to a few of our more public machines this weekend
and if all goes well, I'll put together a debdiff.
