@radieschen I am running a small personal instance ( https://bonfire.fishinthecalculator.me ) on top of the Guix System. I see my setup guide has already been posted, in case you are interested in more details feel free to contact me!

I am also developing an OCI backed NixOS module ( https://github.com/bonfire-networks/bonfire-nix ) which will essentially allow to run Bonfire over NixOS with Podman/Docker, much like the setup I have on the Guix System.
