To hopefully help with your= questions, there has already been some discussion on guix-devel about the = backdoor and how it should be handled now and in the future: https://lists.gnu.org/archive/html/guix-devel/2024-03/msg00281.html https://lists.gnu.org/archive/html/guix-devel/2024-03/msg00292.html The quick summary is that Guix currently shouldn't be affected because a) G= uix currently packages xz 5.2.8, which predates the backdoor, and b) the ba= ckdoor includes checks based on absolute paths e.g. under /usr and Guix exe= cutable paths generally don't match the patterns checked for.
