A large number of unsigned /nix/store paths were uploaded to an S3 cache by mistake and it turns out that this is EXTREMELY difficult to fix. Moreover, these unsigned paths represented several really expensive build products (including ghc and all of its reverse dependencies) and they permanently poison the cache until fixed. This brought development on the tip of our master branch to a standstill today, but fortunately I was able to fix it.
holy shit lol
i think that Nix hasn't been thoroughly tested with some of that tooling....
