DBus Interface
===============

New in blivet-2.2 is an experimental (see the :ref:`todo`) DBus interface. This
interface provides methods for examining blivet's ``DeviceTree``, creating
devices using blivet's ``DeviceFactory``, and removing devices.


The interface uses the bus name ``com.redhat.Blivet0``.
