That is so cool! Such tedious work, thank you for doing it! With the [funding for the full-source bootstrap chain](https://discourse.nixos.org/t/nixpkgs-supply-chain-security-project/34345), I’m looking forward to seeing a full-source reproduced build of NixOS in the future. That would be an amazing achievement.

One question: did you measure how long this full rebuild took? If not exactly, what time-frame are we talking about here? Hours? Days? Weeks even?
