function that transforms a nixOS module into a nix2dream service module.

[DrRuhe]

this would allow users to quickly "generalize" a given nixos service module to each service defined in nixpkgs.

Alternatively, it might be worth exploring migration using LLMs. If the migration guides are written and specific enough, LLMs could potentially produce nix2dream service definitions (although they should obviously be checked and tested before releasing :) ).
