Hello Mr. Lepiller,

Thank you for the tip. For the moment, I want to poke around this issue.
Perhaps I get absolutely tired of it (or find a good hack - and an ugly
patch). I did manage to learn a bit more about union-builds in general. So,
that's a silver lining.

Also, your work on guix-android seems so very cool! Please keep up the
great work!
