Hi Ludo,

Very cool work, I'll have to check it out. One queston and one quick note:

Does the referenced derivation need to actually be in nixpkgs? I assume this works by calling nix-instantiate?

Just FYI, multiple-outputs support is not complete at the nix-store level. In particular, if you have one output of a derivation realized but not all (because you gc'd the others or got the one via a substitutor), nix-store can't realize the non-realized ones directly yet. There may be other issues I'm not aware of too.

Cheers,
Shea
