Our build farms have limited capacity, so they probably won=E2=80=99t keep everything forever, but that=E2=80=99s the mission of Software Heritage (SW= H). Guix automatically falls back to SWH for some time now, and SWH archives all of gitlab.com, so I=E2=80=99m not very concerned: https://guix.gnu.org/en/blog/2019/connecting-reproducible-deployment-to-a= -long-term-source-code-archive/ A shortcoming of our code, as Maxime mentions, is that it doesn=E2=80=99t correctly handle retrieval of recursive checkouts from SWH. That=E2=80=99s= a bug to fix, and there=E2=80=99s another one in this area: https://issues.guix.gnu.org/48540 > Okay great then.

Other than checking whether =E2=80=98guix lint -c archival PKG=E2=80=99 com= plains, one can run: guix build -S PKG --check HTH! Ludo=E2=80=99.
