Looking things up, someone has linked the Flatpak containerisation tech (bubblewrap) into the Nix store: https://github.com/fgaz/nix-bubblewrap

It looks... somewhat abandoned, but I'd wager it still works today. Failing that, setting up a shell alias to launch a regular binary in bubblewrap isn't too hard either.

It's a long standing goal of mine to put together a distro with the system management aspect of NixOS, the isolation of bubblewrap and the lightness of Alpine. I'm gonna start this project when I have time™.
