Yeah that=E2=80=99s something I noticed here:

  https://lists.gnu.org/archive/html/guix-devel/2020-04/msg00032.html

Commit a322e9d16b227484ce04721fee0f99618cb1007e does that.

The result is not optimal yet because it just says =E2=80=9Cduplicate entri=
es=E2=80=9D.
Ideally we=E2=80=99d be able to show a =E2=80=98fold-services=E2=80=99 trac=
e of sorts telling
showing where the faulty entries come from.

Thanks,
Ludo=E2=80=99.
