Subject: [PATCH 1/2] Allow greeter to start dbus and transition
Date: Fri, 21 Dec 2018 01:41:25 +0000 [thread overview]
Message-ID: <20181221014026.2867-1-dsugar@tresys.com> (raw)
The display manager lightdm (and I think gdm) start a dbus binary.
This allows that to happen in a special dbus domain.
