Not much else different? That’s kinda what I expected, about the same experience, just in Guile Scheme instead of Nix and with a different package repo.

How is Guix? I run NixOS right now, and I didn’t find Guix until like right after I invested all the time and effort to learn Nix. I kind of want to switch, but I also don’t really want to abandon Nix right after I learned it.

No, I think they understood. Android needs those settings because the process is automated. A Linux device would probably not automate updates like that and let users choose when to do so, which means they can just not do it until they get to WiFi.
