[arch-releng] automated installation media builds?

1) should we automatically build images all the time and improve things gradually instead of releasing every 2 kernel versions? I think we should. It would be nice to have "testing" images continuously updated, and perhaps a way for users to easily provide feedback so we can have an idea on how stable the images are. and sometimes we could still build/release "stable" images. But, IIRC some people (Aaron?) said some mirror admins might not like the increased traffic caused by continuously changing images. 2) how clean are our chroots at this point? It should be safe to just run '/usr/local/bin/releng-chroots recreate' whenever we want, but afaik we had various patches. are all of these integrated now?
