@SomeoneSerge I thought I had more things pending on the documentation side but I think this is the only comment that was pending from your side. Please let me know if I overlooked something.

As promised I'll check how to improve the implementation with a proper closure support.

As promised I'll check how to improve the implementation with a proper closure support.

I forget if I mentioned but it's a similar problem in nix-required-mounts (it's using exportReferencesGraph but it could be still more general than that) and we should probably write a more abstract tool solving both tasks so we can test it better...
