The distribution constructor creates images based on settings specified in DC manifests. DC manifests are XML files that contain specifications for the images you want to create. The distribution constructor package includes sample manifests to help you build the images.
All the fields in each DC manifest file provide preset default values that will create the type of image you need. You can edit fields in the manifest file to further customize the resulting image.
You can also create custom scripts to modify your installation image. Then, you add checkpoints to the manifest to run these custom scripts. Checkpoints enable you to stop and start the image building process for purposes of debugging. At the end of the process, a simple log file and a detailed log file are generated.
