+create_htb <int>
+Whether or not ulogd should rebuild the htb hierarchy (when using FPS). 0 will
+not rebuild it, any other value will. Set this to zero when the hierarchy is
+managed externally (for instance, by PlanetLab's node manager). When this is
+set to 0, identities require htb_node and htb_parent properties in the drl xml
+config.
