I don’t provision any two devices exactly the same way, and if I did there’s nothing stopping that provisioning script/tool from changing or becoming out of date over time since I’d only run it once every couple of years. I briefly looked at nixos but as another reply said, the major hurdle was the documentation and trying to get “the right way” to do things. I remember flakes being mentioned but being experimental and there being two other things competing as the solution to the same problem and at that point I lost interest. I moved to fedora for the first time in a decade recently and installed what I needed via dnf. It wasn’t a difficult enough process to justify learning another programming language.
I’ve not used it in anger but the principle just seems like inline-styles with extra steps. However I’ve also had to change something in a large project that had a lot of dedicated classes with specific and shared styles and trying to sort that out without breaking stuff was a massive pain.
