The present invention allows Red Hat Package Manager (RPM) systems to work with non-RPM packages. In particular, the present invention provides for installing an RPM subsystem on a system that has its own native packaging subsystem. The RPM subsystem is initially delivered as a package wrapped in the non-RPM format of the native packaging system and installed. An administrator may then install RPM packages using the RPM tools of the RPM subsystem. When an RPM package is installed, the RPM subsystem is also configured to create a stub entry in the native packaging, non-RPM system. The stub entry may contain the normal package information, such as name, version, description, as well as a list of files contained in a package. The stub may also contain uninstallation logic, which serves as a "callback" into the RPM subsystem during package removal and causes the RPM subsystem to remove the package when invoked. Removal of a RPM package via RPM tools also causes the removal of the stub entry. Accordingly, both the RPM subsystem and native packaging, non-RPM subsystem may have consistent states.
