Mostly, yes (=E2=80=9Cmostly=E2=80=9D because derivations using =E2=80=9Cbu= iltin:git-download=E2=80=9D will automatically be fixed once we=E2=80=99ve updated the =E2=80=98guix=E2= =80=99 package, but that only helps if you=E2=80=99re traveling to after September 2023 (commit 13b0cf85eb31e1b1ea674debbbfb0f35a32d1374). > For instance, redoing your ReScience paper from 2020 using only SWH as I > did [1] some months ago is now broken (because a change on SWH side). Indeed. :-/ That=E2=80=99s a real bummer, but that=E2=80=99s the nature of software: we= cannot retroactively fix bugs. > Well, I am fine to keep this bug closed but for the posterity we need > something like: > > guix swh get -C channels.scm -m manifest.scm Exactly! We have the demonstration of just how important that is. Ludo=E2=80=99.
