My household primarily runs Arch and Artix for our desktop OS and never have any issues with it, however we have had no end of issues with our home server* and it often ends up being related to systemd.
I am ideally looking for something that can just be left and updated less frequently that can also run docker containers, ideally using OpenRC but can also occasionally run a package on the host system. I’d prefer something GNU as well.
Please don’t reply with any “systemd works fine for me” or “what is your problem with systemd” like most that a search turns up.
Edit*: Probably should have mentioned that its been on CentOS, Ubuntu and then OpenSuse Leap
Alpine is without Systemd tho? I see no issues there. It’s primarily made for containering too. Their init uses busybox, afaik.
Obarun comes with the excellent s6 init but uses pacman as pkgmanager, rolling. Void is semi-stable afaik, but might still fit your bill.
Then there’s Devuan (mileage my vary, since it’s a fork) but they use a weird Runit/Sysv-hybrid if you choose Runit. Or old and clunky SysV, by default. Maybe Knoppix/MX works better?
Gentoo can use OpenRC but you want stable. (there’s even an s6 repo, yay!)
AntiX, Slackware, DSL, IPFire, i have no experience with.
