The purpose of 'groundhog' is to support reproducible research. As Uwe Ligges pointed out, there are practical limits to that. Since I am typing this on a 10-year-old machine, it's clearly feasible in *some* instances, but as an illustration of Uwe's point, Ubuntu still supports 32-bit applications, but it does not support 32-bit x86 hardware (since 20.04 IIRC).
I think it is fair to say that 'groundhog' *supports* reproducible research, but nothing can *guarantee* it.
