RPM binary bundles and packages can be created using the -native flag. The flags -rpmlicense and -rpmprefix can be used to insert alternate information in the rpm header of each package. The binary bundles are a collection of rpms that are wrapped in the same way that GPT packages are. Therefore they can be installed the same way the other binary bundles are. When the bundles are installed the information in the bundle definition file is not stored in the RPM database. The database will contain the information for each package in the bundle. GPT does not have any way to create source rpm's.
