NixOS-like services for Nix flakes, as a [process-compose-flake](https://github.com/Platonic-Systems/process-compose-flake) module (based on flake-parts).
Thanks to [the devenv project](https://github.com/cachix/devenv/tree/main/src/modules/services) on which much of our services implementation is based on.
This is currently not possible (nor prioritized by the devenv project), which is why we must create our own services. See https://github.com/cachix/devenv/issues/75
