legacyPackages
Can now also build with (1) instead of just (2) - `nix build .#topology` (from `legacyPackages`, hidden in `nix flake show`) - `nix build .#topology.${system}.config.output` (raw flake output)
Export all `./nix/` flake modules Modularize `configurations` on `machines` dir Also move `toposort` images to a single attrset binding
