We have successfully created an independent, bit-by-bit-identical rebuild of the nixos-minimal ISO published by Hydra 🎉 Why is this useful? While there are a number of ‘side-benefits’, the main point of Reproducible Builds is that it gives us a reliable way to verify the binaries we ship are faithful to their sources, and have not been tampered with anywhere in the build pipeline (e.g. on Hydra). For general information on Reproducible Builds see: What exactly was reproduced? This me...
A large amount aren’t but, OTOH, a large amount also are because Nix does almost everything it can to set up an environment without easily preventable sources of non-determinism such as general filesystem access, networking or other means of communication with some uncontrolled system.
Reading this thread I am even more confused about Linux in general.
