I use etckeeper. https://wiki.archlinux.org/index.php/Etckeeper https://wiki.archlinux.org/index.php/Etckeeper I find it nice to be able to simply make changes as I need directly on the system without going through any config management abstractions. But then I have a record of previous state a can revert to. It's simple and works well.
