I use git branches to deal with this.
My `develop` branch would contain the test config, and all development
would be done here, or in branches merged back into here.
I'd then create `server-test` and `server-live` branches (you may have
more or less, depending on your workflow) in which I'd modify the
config for that server.
I only ever merge from `develop` into the `server-*` branches - never
back into `develop`.
