version of Publican (docbook building tool). The one we have in 10.04
(1.0~20090927-2) is really outdated and sometimes causes issues (build
warnings or errors) when documentation build scripts run. Precise comes
with 2.8-2 which I use on my dev box and works fine.

In light of the recent arguments put forward by Paul wrt some xen bug in
the kernel being a potential reason for the frequent crashes we're
suffering (it is not proven that it's indeed the root cause btw), I
think it would be worth a shot to try an upgrade now. I think
12.04LTS/precise has been out long enough that major issues would have
been sorted by now.
That said, except for the publican issue I mentioned above, there are no
major immediate benefits that I can see, other than running generally
more recent software - which can also be a shortcoming as we could be
introducing new issues ;-).
With regards to the upgrade process, I do not recommend upgrading
in-place, due to the long potential downtime and risk of failure
As I was saying in some other e-mail, I think we should instead work on
a copy of mantisbt.org as a test platform. That means running 2 servers
concurrently (assuming Linode allows us to do that), the live site and a
test upgrade one. If the upgrade proves successful, then we can bring
mantisbt.org offline, copy the databases over to the upgraded box then
switch the images.
