Ah. Simple implementation.
I *will* give them that. Vanilla SysV init was a bit too complex from that perspective.
The tragedy of the prevalence of false dichotomy arguments is that it prevents people from exploring other alternatives.
(For the record, I *do* use systemd on some boxes. I don't love it, nor fear it. It has some strong points, but is desperately in need of a serious code audit, and some *massive* scope-creep policing)
