NixOS is a Linux distribution built around the Nix package manager. Unlike traditional Linux distributions, NixOS is configured using a functional language that describes the system configuration. It generates complete system profiles, enabling reproducible deployments, atomic upgrades, and system rollbacks.
NixOS relies on the Nixpkgs collection of package definitions and the Nix expression language for declaring packages and system options. It is free and open-source software under the MIT License.
