But it's also a load of unrelated utilities like this one. Unfortunately if you get systemd as an init system, you generally get all this other stuff (unless you take steps to remove them, which in some cases is simple and in others is painful).
Some of these utilities might be a good idea, but they should be separate projects, not bundled.
