The current beta apache config is somewhat of a mess. It's diverged, and is well behind that of production.
After Giuseppe has merged and deployed (and it's working!) https://gerrit.wikimedia.org/r/#/c/170300/ I'm planning on rebuilding/rebasing the beta cluster apache config ontop of the current production one, so it's not so far diverged.
We can then probably try and then get some puppet magic to have it deploy 2 versions of the config (templates?), without having 2 physical versions on disk.
We might be actually able to do something along those lines to do the beta config from production... Maybe?
