4.4. Extending polkit Configuration

Support for replacing the back-end authority implementation has been removed. A similar level of flexibility can be achieved by writing a JavaScript .rules file that calls an external program.
Support for replacing the PolkitBackendActionLookup implementation (the interface used to provide data to authentication dialogs) has also been removed from polkit in Red Hat Enterprise Linux 7.
For more information on polkit, see the polkit(8) man page.
