Linux doesn't have to be complicated, even today. Slackware and Void are BSD-like in their configuration simplicity. But I appreciate the BSDs being there... especially since they have code bases that are squeaky clean and thoroughly documented, at least by Linux and GNU standards.
I've been meaning to look into non-systemd distros -- assuming you're putting Slackware and Void up as examples of that -- how do things like Docker or others that seem to require systemd cope?
Docker runs just fine on my Alpine box. You just have to ensure dockerd is started upon startup.
I don't faff about with GNOME or any of that, so if you want to run GNOME you may be out of luck. GNOME can be built without systemd dependencies, but it's probably a PITA, especially on Linux.
well there was that one big black eye with FBSD code quality with that whole wireguard fiasco... something about a rush job paid for by the Netgate folks
