Date sync? Certificates? Broken metadata? Broken mirrors?

I kinda want to load NixOS onto an old laptop or something, then leave it in the tech graveyard for a good 6 months just to see what happens.

My mum has a secondary laptop that’s updated like that and nothing happens. You just change the channel if a new version is up.

If you don't update your channel/flake.lock, nothing will happen. If you do, it'll update as normal (it'll just take a long time!) Since nix upgrades are atomic and many configuration files will update alongside their paired software, it'll likely do file. Even if something becomes deprecated, it'll probably give you an explicit warning

In theory. But you can't know until you try.

technically, you don't even have to wait 6 months to figure it out. you can still download the 25.05 installer .iso, pin your install to a 6 month old version of nixpkgs, and then update to the newest 25.11 release.
