Blog post by @luj that escaped my attention until now asking just how reproducible nix and NixOS is at scale? Turns out, he's been studying this exact question since 2017 and did a part of his PhD study on it. https://luj.fr/blog/is-nixos-truly-reproducible.html The answer? In 2017, about 60% of builds from nixpkgs were bitwise reproducible. Now, it's over 90%. This is great news! Especially since we don't have any tools that actively monitor this, so there isn't any active process that enforces reproducibility outside of nix itself (and the reproducibility team, let's not forget) Great work, and great writeup. I look forward to reading more in the paper he teases in the post. #Nix #NixOS #nixpkgs
