I use OpenBSD on my prod machine and vps, and that's serving me very well (other than suspend and usb expansions cards being buggy on my framework laptop (latter might be hardware issues))

I have the default SteamOS on my steam deck; I'm not a fan of its immutable filesystem paradigm and not shipping with any real package manager besides flatpak, so I'm thinking of putting Void Linux on it at some point.

My phone runs PostmarketOS (alpine based mobile OS); which is adding support for systemd and making it default for phosh, kde and gnome installations; which I'm disappointed about to say the least. openrc will still be supported, but given it's no longer the default (and requires recompilation to change), it's probably taking a backseat to systemd. openrc will still ship by default on sxmo, but I'm ready to find an alternative at this point. Maybe I should look into trying to port OpenBSD to the pinephone again, as much as a dream as that seems like. Looks like there's also been some effort put into porting Void Linux to the pinephone, so I'll check that out.
