+       On start, the server opens a transport, creates a mutex and a shared
+       memory section containing the related session bus address. This mutex will be
+       inspected by the dbus client library to detect a running dbus session bus.
+       The access to the mutex and the shared memory section are protected by a
+       global lock named "UniqueDBusInitMutex".
+      </para>
+      <para>
+       The mutex and shared memory section name depends on the value of the scope
+       attribute and are listed in the following table:
