as nixos user i looked at habitat and the thing that i will never switch to habitat is that environments are not (build) reproducible. basically habitat is more like docker where it snapshots "successful" build and you use that input for further building.

what i loved about habitat is the supervisor part. i there is a way to use habitat's supervisor with nix. then you get best of both tools.

until then i'll just have to stick to python's supervisord.
