Right, =E2=80=98guix pull=E2=80=99 doesn=E2=80=99t survive updates of the b= ootstrap Guile tarballs, because it doesn=E2=80=99t try to download it (see =E2=80=98build= -guix=E2=80=99 in guix/build/pull.scm.) That=E2=80=99s rare in practice, but still a serious limitation as you note. :-/ There are other things to do in =E2=80=98guix pull=E2=80=99, such as authen= tication, and improved bandwidth usage. For the latter an option would be to resort to git, and perhaps for the former too. Ludo=E2=80=99.
