Code review comment for lp:~mbp/launchpad/800295-delete-buildd

it turned out that it is not easily possible for lamont to change the setting, so in http://bazaar.launchpad.net/~launchpad-dev/launchpad-buildd/trunk/revision/17 i've made it just autostart based on the hostname, which should be tolerably safe for other people without disrupting the buildds

i've added python-lpbuildd to launchpad-developer-dependencies in https://code.launchpad.net/~launchpad-committers/meta-lp-deps/trunk

i apparently need to manually update the ec2 image before it can be relied upon

i've created a recipe building from lp:launchpad-buildd into the launchpad ppa
