+        launchd is a open-source server management system that replaces init, inetd

+        launchd allocates a socket and provides it with the unix path through the
+        DBUS_LAUNCHD_SESSION_BUS_SOCKET variable in launchd's environment. Every process
+        spawned by launchd (or dbus-daemon, if it was started by launchd) can access
+        it through its environment.
+        Other processes can query for the launchd socket by executing:
+        $ launchctl getenv DBUS_LAUNCHD_SESSION_BUS_SOCKET
