The idea is to use another module which will replace your <filename>configuration.nix</filename> to configure the system that would be installed on the CD. </para> <para> Default CD/DVD configurations are available inside <filename>nixos/modules/installer/cd-dvd</filename>. <screen> <prompt>$ </prompt>git clone https://github.com/NixOS/nixpkgs.git <prompt>$ </prompt>cd nixpkgs/nixos <prompt>$ </prompt>nix-build -A config.system.build.isoImage -I nixos-config=modules/installer/cd-dvd/installation-cd-minimal.nix default.nix</screen> </para> <para> Before burning your CD/DVD, you can check the content of the image by mounting anywhere like suggested by the following command: <screen> <prompt># </prompt>mount -o loop -t iso9660 ./result/iso/cd.iso /mnt/iso</screen> </para> <para> If you want to customize your NixOS CD in more detail, or generate other kinds of images, you might want to check out <link xlink:href="https://github.com/nix-community/nixos-generators">nixos-generators</link>. This can also be a good starting point when you want to use Nix to build a 'minimal' image that doesn't include a NixOS installation. </para> </chapter>
