I’m not sure I agree with this… I’m using nix on several different generation thinkpads, two older generation MacBooks (one air and one pro), two different older generation imacs, as well as my home built PC, and an OEM built pc… All with little to no tinkering whatsoever.
All my tinkering was first setting nix up and figuring out how to use it… Then I saved and copied my config and use the same one on all the machines (albeit with subtle changes on first install).
I’ve used arch a handful of times over the years, and it is without question, significantly more “needy” over time, imo.
