You can rely on the maintainers of the Linux distribution to do the work for reproducibility. While also providing security updates. And vetting packages for licensing issues. That's what distributions are for.
You can for the packages they support and at the specific versions that they support, but if you have other packages you’re on your own.I certainly appreciate the package maintainers’ toil, but it would be better for everyone if they weren’t doing work that would be easy for a program to do.
