<title>Building Your Own NixOS CD</title>

<para>Building a NixOS CD is as easy as configuring your own computer. 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>
$ git clone https://github.com/NixOS/nixpkgs.git
$ cd nixpkgs/nixos
$ 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>
# mount -o loop -t iso9660 ./result/iso/cd.iso /mnt/iso</screen>

</para>
