To ``add MATE'' means that @code{polkit} and @code{dbus} are extended appropriately, allowing MATE to operate with elevated privileges on a limited number of special-purpose system interfaces.  Additionally, adding a service of type @code{mate-desktop-service-type} adds the MATE metapackage to the system profile.  ``Adding Enlightenment'' means that @code{dbus} is extended appropriately, and several of Enlightenment's binaries are set as setuid, allowing Enlightenment's screen locker and other functionality to work as expected."

Occasionally, a service does not map to a daemon.
