That's what I did as well. But I also continue to use Slackware which doesn't have any current plans to move to SystemD.

It was the first Linux distro I ever used and I still love it to this day. I've used many different systems for work over the years but I've kept at least one Slackware laptop or desktop going since early 1995 when I first found a Slackware CDROM in the back of a book about learning Linux.

Although it gets new software, bug fixes and minor updates here and there it's remarkably similar today to what it was then. And I find it Just Works, I've had very little trouble with it over the years.

I think I like it too because it always felt like the most traditional Unix like distro I've ever used and also more BSD than System V which I also generally prefer.

I do have Slackware as well, so far it hasn't left its roots.

I like OpenBSD a lot, but I have to nitpick your description: OpenBSD diverges from "standards" when they decide the standard doesn't make sense. They are not afraid to tear down working things when they decide it's necessary, and I've faced a lot of release-to-release breakage, forced reconfigurations, or features I've relied on go completely missing without a lot of warning.

Still a great project that I use every day, I'm not knocking it. It's just not a great example of a change-averse type of stability.
