@novet Flakes are a mechanism for distributing Nix files, but you can't reference them without a revision lock or update them without rebuilding the system that includes them.I think what @johbo said is about right – when we want a live deployment of an application, we don't think about that on the "core system" level, we ideally want to have a separate layer just for "end-user" applications that can be more dynamic. But with NixOS that isn't really possible.
