The distribution constructor creates images based on settings specified in XML files, called manifest files. The manifest files contain specifications for the contents and parameters for the ISO images that you create using the distribution constructor. The distribution-constructor package provides sample manifests that can be used to create a custom x86 Live Media ISO, an x86 or SPARC Automated Install ISO image, or an x86 or SPARC text installation ISO image.
The elements in each manifest file provide preset, default values that will create the type of ISO image you need. You can manually edit these preset elements in a manifest file to customize the resulting image. In addition, you can create custom scripts to further modify your image. Then, reference the new scripts in the manifest file.
