OpenRC, s6, rc.d (the BSD), are more simpler than the systemd ecosystem which is feature ladden and not easy to use on the common line. They are also way easier to hack upon, especially when you want to run a lean system (small vm, containers). systemd feels like running windows server for a small php application. The happy path is easy, anything outside of that is torture.
