Gentoo Linux

Ha, yeah - the Arch wiki calls it a "service manager" although OpenRC describes itself as a "dependency-based init system". When I wrote that reply I'd started to be more pedantic about the terms but changed it to reflect my core problem that it's not an apples-to-apples comparison to compare all of systemd to the underlying init system (you see loads of "are you using OpenRC or systemd" posts but never systemd vs sysvinit).
