Comment 18 for bug 251923

Well, the straightforward workaround for this should be:
 - create a shell script named 'mount' that maps 'mountvers=2' to 'nfsvers=2' and calls /bin/mount
 - put this shell script in /usr/local/bin
 - make sure /usr/local/bin is in the path before /bin
 - call /opt/tta_tem/bin/tem startcdm

If that doesn't work, you can use 'dpkg-divert' to permanently move /bin/mount aside in a way that will be respected on upgrades, and install your script directly as /bin/mount.

That's as may be, but we didn't touch it. You'd have to take up the question of not touching it with linux-nfs upstream.

This is not due to any Debian or Ubuntu changes; it's due to an upstream change, probably one that was meant to fix something else and only incidentally broke mount version 2 support. And it probably went unnoticed because the only thing affected was a version of the protocol that's been *obsolete* for a decade.

I agree that it's a bug to have the option stop working. I also think it's a bug that the software you're using is setting that option. Neither of these bugs are going to be a high priority for the Ubuntu team, because the number of users affected by problems with NFSv2 support is very, very small.

If by "upgrade a few packages" you mean "upgrade to the next version of the release, which is not guaranteed to be feature-compatible with the previous version", sure.

The way I see it, you have several options to get this bug fixed.
 - Talk to upstream.
 - Work out how to fix it yourself.
 - Contract someone to fix the bug. There are a number of companies that provide paid support for Linux distributions, including for Debian and Ubuntu. For information about Canonical's paid support options, see <http://www.ubuntu.com/support>.

But escalating the bug via the community bug tracker is not likely to lead to a fix in the foreseeable future, because this is going to be a deep bug and there are a lot of other bugs that need fixing.
