imho, he is missing the most important point, and walking in the wrong direction instead.<p>He is true, that science requires recomputation, the ability to verify or falsify results. But recomputation in science is more then just the ability to run the black magic box again. A black magic box makes it worse, because the box might change and fail over time, and its black magic VM. Recomputation requires source code, that is human readable.<p>So my suggestion instead is to use a combination of Gentoo and Linux Containers instead. Gentoo enforces that everything on the machine has its source code that did run through the compiler, and Linux Containers encapsulate the project in a way, that a simple backup can preserve it.<p><i>well</i> I normally prefer Debian because of lower maintenance cost. But Gentoo could play out its strength in this edge case.
