> An already built container is reproducible in the same way that a binary artifact is reproducible. Nix is reproducible to its core, including hash integrity of every tool used to execute the build. Anybody should be able to build a bit-for-bit identical copy from scratch. This is the goal, but not actually the case. Nix/guix does many things to make reproducible outputs more likely, however people are very good at putting things in a package that are not deterministic, such as the build time down to the milisecond.
