> I agree Arch and rolling release is great to avoid breaks. Paradoxically, people are afraid of it for the opposite reason. > I am considering to migrate to NixOS or GuixSD (currently toying with 2 virtual machines). I find Arch to be a great imperative distro, but functional ones are simply superior. Declarative system configuration, declarative package recipes, and the ability to install multiple versions of the same package is key if you have a complex setup (e.g. doing deep learning). I've been eying NixOS, but haven't heard of GuixSD. I'll look into it, would be interested to hear your comparison. The main downside to NixOS seems to be package availability. I get the impression that you spend a lot of time repackaging things for it because the coverage isn't there yet.
