I'm very sure you are actually just rebuilding the container images themselves, not the package tree you are depending on. Building reproducible ISOs, or container images, with a package repository as a base isn't particularly hard these days.

I see what you mean. Thanks for clarifying. Even so, Nix is no worse placed than those other distributions for bit reproducibility. Correct?

It's unclear at the moment because of the limited testing (minimal ISO and a Gnome ISO) vs Arch/Debian/Guix rebuilding entire package repositories.
