Arch is only the larval stage. When a Linuxite consumes enough CLI, they metamorphose into one of two adult forms: a Void user, or a NixOS user. As these two adult forms are incompatible, this is a rare case of species divergence within a life cycle. Even more oddly, like the axolotl, many Arch users never leave the larval stage, and continue living comfortably in their ecological niche.
