Just the PID 1 manager is multiple times larger in LoC than any alternative. There is no metric in which systemd is more lightweight that I could find.

I'm not sure this is true in practice, if we're counting init scripts themselves. Which we should, because init scripts are code and they often re-implement standard systemd features. Usually in wonky, broken ways.

		What about other init systems? The GP said "any alternative." I am not familiar with how complex they are but was under the impression that there are a number much simpler than sysv init?

		I think that even if we count init scripts which are way different level of complexity than C LoC, the Systemd would still be larger. Especially if we count just the scripts that are deployed.
