I’ve used NixOS on my laptop as a learning experience for the past year and find your summary solid. Rollbacks = 🍰. The bug bear for me has been the Nix language itself. It’s functional, (a first for me,) and with the documentation lacking, I’ve been thrown for more than a few loops. That said, i have indeed learned quite a bit as a result. Still a ways to go but here’s to the journey!
