feat: nixpkgs-ify and unflake-ify system-manager
Make it easier to use system-manager as a flake-library.
Will remove from all dependents at least 230 lines worth of locks from this project (Example), while still keeping the same library.
Further adds flexibility to calling the libraries and package adding the possibility to use default.nix or invoking the files directly. (Example)
Note differences in calling lib.nix directly, the removal of the flake layout of default.nix being a breaking change, and most importantly the packages.nix only having a single wrapped binary output called system-manager instead of the four previous ones. Open to change anything here (like adding back packages).
Thanks for this project! :tada:
Note, using system-manager outside of a flake.nix is entirely untested currently.
TODO: Should add in aliases for the removed packages? Possibly re-add them? Unsure if they are meant to be used outside of system-manager's development cycle.
Tried to find a better way to expose the nix-vm-test project, but i cannot really find a good way to let it auto update but also not propagate as a dev dependency to all users of system-manager.
We could eye out moving all the nix libraries in here to a system-manager-modules as well as making a PR to nixpkgs to add a system-manager based upon the work here. Then it would become a lot simpler to use system-manager, and there wouldn't be a need to simply the developer nix flake here. Only add a new input for inputs.system-manager-modules for the modules.
But it is annoying to have to split it up like this however.
Another way is to create a ./dev flake, we do this in a couple of projects. It allows hiding the dev dependencies from the user's flake.lock. You can find an example of it in https://github.com/nix-community/srvos. This would make the management of the nix-vm-test input easier.
But this is good enough to be merged already.
