Right now.
I’m running Dietpi (Which is pretty much a “tweaked” debian) on my orange pi 5 max and arch linux on my x86_64 pc. Both are bare metal installations, so the “killer feature” is, er… whatever I want, pretty much. I also have a orange pi zero 3 running dietpi serving me nextdns under docker… and another orange pi zero 3 serving as my “Theres a blackout going on in town and all I have to do is to play retropie” pc.
Been using sway on my orange pi’s and hyprland on my x86_64 PC for years and I never had any issues with em. And I suppose with openbox the experience will be exactly the same thing.
