Hello,

Hartmut Goebel <h.goebel <at> crazy-compilers.com> skribis:

This is expected.  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!
