Question for the beautiful people out there who main guixsd: did guix's whole reproducible builds thing prevent the xz backdoor? I heard it was only present in binaries from the maintainer, so #guix should be immune right?
@aeva it was only (fully) present in _source tarballs_ from maintainer (but not in the repo), so that depends on where guix was getting its sources from.
Also, its activation conditions were pretty strict (both at build time as well as at runtime), so there's a good chance it wouldn't enable itself there even if the malicious sources were used.
@robryk aaaah
