Upgrade to jaunty

AMD64 dist upgrade to jaunty from ibex.

Waited a month for the Ubuntu servers to calm down after the initial release. Didn't get all packages downloaded on first try, but the installer picked up where it failed and worked on the second try.

• postgrey moved from port 60000 to 10023, had to update postfix/main.cfg
• ufw: keep current rules

After reboot, all seemed to be working except for the wiki which yielded SQL errors on some pages and wouldn't allow any edits.

Luckily, I knew the following trick:

php /var/lib/mediawiki/maintenance/update.php

That put everything in order immediately.

Trackerd doesn't seem to be working very well. It says the index is corrupt and offers to re-index everything, but then fails with the index is corrupt error.
