Isn't that exactly what your first source and OP are about? They check that the binaries are the same when built from the same sources on different machines. The point is exactly that the binaries don't change with every build.

Yeah, that represent maybe 1% of the packages in nixpkgs (only the installation iso).
Sure but the goal is the same, binary reproducibility, and it is systematic. It's just less far along than Debian.
Also I'm pretty sure a big percent of nixpkgs is already reproducible, we just don't know for sure.
They say the next step might be the GNOME-based ISO, which would be a big achievement because it's basically a full-featured system.
