Comment 1 for bug 689961

Actually, can we have the pidfile be written to /srv/codebrowse.launchpad.net/var/ (for production), which I think is where it was before. We also need to make sure there's some way of preventing pidfile locations from changing in production (unless we really want to, and have warning ahead of time) because initscripts depend on them, and if they change, it breaks rollouts in a very painful way.
