As the article notes, NixOS' design increases reproducibility at certain levels and in certain respects, but not all. In particular, it doesn't have any magic for achieving the final condition for 'reproducible builds' as in reproducible-builds.org: guaranteeing that builds given the same sources produce bit-for-bit identical binaries. For that kind of reproducibility, NixOS is on the same quest as other distros like Debian and Fedora and Arch— and benefits from the work developers of those distros do with upstreams to eliminate non-determinism from their build processes and tools.
