Debian, installed without systemd as per the wiki. So far I've not hit any issues, whilst I've recently ended up diving through both kernel and systemd code to find the root cause of an issue I was hitting on one server. I could have just bodged past it, but I wanted to actually understand what the issue was, and what else it was going to affect.

Alpine Linux would be my favourite, although I only use it as a server distro. I use Artix as my daily driver for personal computers because of the AUR and glibc (Alpine is musl). I also enjoy Void but it's not got as much software as Artix repos + AUR.

I don't care about the init system, however i do love void mainly because of the package manager.

I like FreeBSD, OpenBSD, Alpine, and Devuan.

Artix is an under-appreciated gem.

What's SystemD and what is it bad?

Guix

I have to write startup scripts time-to-time and I have to say that I don’t miss at all the old init-system.

Not that systemd don’t have flaws, but in old init-system even simplest daemon took too many lines. Not to mention hacky comment definitions.

PalmOS. So simplistic yet powerful. I miss those old PDAs :(

Debian that i haven't updated in 10 years

Lot's of Systemd apologists, barely one answer to the question.

I misread and wondered when did systemd release cat as in the software not the animal.

Offtopic, but... Another ANeko user :D

OpenWRT

Totally Guix, it has no systemd and is able to roll back to the last working in case you break anything somehow

postmarketOS, though they are in the process of migrating to systemd. Not that I personally mind terribly much, even if it feels like a bit of an odd choice. So maybe I should say Alpine.

MacOS.

But my actually favourite OS does use systemd.
