Building the app is not the problem, Nix adds minimal overhead for that. Deploying the app is annoying because changing a systemd service requires a nixos-rebuild, which is pretty slow on a Raspberry Pi.

There’s no good way to have an auto-updating non-NixOS systemd service on NixOS, because it’s not designed to co-exist with other things.

Also, NixOS is pretty much a DSL around systemd for this kind of thing. Systemd is already fairly declarative, so the indirection seems a bit unnecessary.
