I'm afraid you're mistaken. Taken directly from https://reproducible-builds.org/ https://reproducible-builds.org/: "Second, the set of tools used to perform the build and more generally the build environment should either be recorded or pre-defined" FWIW, I'm a committer on a Linux distro specifically constructed to guarantee build reproducibility (nixos.org), so I'm pretty sure I know what is generally meant by "reproducible builds" in common industry vernacular. Byte-for-byte is important, but that's hardly the whole picture.
