text: libgtop is not reproducible, since it embed the output of into one of its binaries. See or build on 2 machines with different kernel versions. Report attached since r13y will not keep it, I think: libgtop build should be reproducible. This patch works from a nixpkgs perspective: However, it should ideally be reported and fixed upstream.
