As expected from the docs, that's why I was surprised to see you mention Nix on a Chromebook, it seemed like order of magnitude wrong. 128GB is an unusual amount of local storage for a Chromebook.

I have a little Arch/Hyprland install that fits a comfortable environment in like 8 of the 16GB in my Dell 3189 right now - It was kind of a fun project fitting it and chasing down all the little annoyances, I think it all works now other than the lack of pluming to make use of the fold sensors, and an occasional ASoC bug for which patches have landed upstream in Linux or Pipewire since the last releases.
