Pinning Nixpkgs, wiring NixOS modules, and managing system generations all matter, yet they can be hard to connect into a day to day workflow.\u003c\/p\u003e\u003cp\u003eThis book walks you through concrete upgrade and rollback drills so you can treat NixOS as an operational tool, not a science experiment.
