https://github.com/nix-community/nixos-generatorsA tool previously used to build various NixOS system images such as ISO, cloud images, and VM images. Now deprecated as of NixOS 25.05, its functionality has been integrated into the core NixOS nixos-rebuild build-image command.
To build a standard ISO image, use the nixos-rebuild build-image command with the --image-variant iso flag.
If you need to explicitly specify your NixOS configuration path and a specific nixpkgs checkout, use environment variables:
NIX_PATH=nixpkgs=../nixpkgs NIXOS_CONFIG="/etc/nixos/nixos-configuration.nix" nixos-rebuild build-image --image-variant isonixos-rebuild build-image --image-variant isoWhen using Flakes, you can build an ISO image from a specific NixOS configuration defined in your flake output (e.g., nixosConfigurations.myhost) using the --flake flag.
nixos-rebuild build-image --image-variant iso --flake .#myhostAlternatively, if you want to expose an installable package within your flake (similar to the old nixos-generators.nixosGenerate function), you can access the system.build.images attribute in your configuration:
packages.x86_64-linux.myhost-iso = self.nixosConfigurations.myhost.config.system.build.images.isonixos-generators is deprecated because its functionality has been upstreamed into nixpkgs. The primary replacement for the nixos-generate command is the new nixos-rebuild build-image command. Users should migrate to using nixos-rebuild for building system images.nixos-generators and their status/equivalent in the new nixos-rebuild build-image command. Use the --image-variant flag with these names to specify the output format.
