The issue was that if you build a tarball with guix pack, without guix time-machine, you can't reproduce it with guix-time-machine. Between the two tarballs, everything is the same but the provenance file. So here the idea is to make sure that the provenance file is the same between tarballs made with and without guix time-machine. Here I get a diff between tarballs made with and without guix time-machine, with or without your patch, so the patch doesn't fix it yet for guix master of yesterday. Between when I reported the bug and the test I did yesterday, the HEAD of guix master changed though. Denis.
