Fair play, as you say it is a “love it or hate it” affair. I personally really like the simplicity and stability of old school UNIX.
OpenBSD comes to mind as the closest thing in contemporary times and I would use it as a daily driver but I need Linux for a few bits.
Void to me seems like the Linux equivalent. Minimal, stable, no bullshit. Alpine also fits this criteria but is a bit more sparse in some packages that I use. Both great distros.
Systemd is 1.5+ million lines of code! However convenient, it felt forced by Redhat into the Linux world and many of us who do not like it feel bent over backwards to be fucked in the arse by Poettering et al.
As solely an init system, may I suggest a superior alternative, s6?
