Strictly speaking, we’re talking about two different package objects, hence the different IDs. Now, there are cases were we have multiple package objects mapping to a single derivation. That’s OK. You can use “guix graph -t bag” or similar if you want nodes that correspond to derivations. HTH! Ludo’.
