Void Linux on my Thinkpad and Thinkstation. On Pinephone and Pinetab I'm running postmarketOS. I really like postmarketOS and using apk, so if I were to get a new laptop or every change the distro on my laptop or desktop, then I might try Alpine. On raspberry pi 3, it's raspbian. I use that mainly to run pi-hole and pivpn.

I distro hopped for a little while, but then settled on Void. It does what I need and was easy to get set up how I want. It's a rolling release and I haven't ever had any big issues with upgrading. The worst issue I've had was when they recently removed pipewire-media-session and switched to wireplumber. After checking a couple posts on reddit and on void's documentation, I got it set up the recommended way without any trouble and audio is working fine.

edit: wanted to add that my Thinkpad also has OpenBSD as a dual boot option, but I haven't booted into it in a long time. One day I'd like to try a BSD as a server(not on a laptop, of course.) Also, the Thinkstation has Windows 10/Void dual boot, but I never boot into Windows.
