* On some systems/configurations, dahdi init script may kick in during the time that hotplug scripts are configuring spans. * It may lead to a race since the init script runs "dahdi_auto_assign_compat" which calls "dahdi_registration" and that tries to run "dahdi_span_assignments auto ..." * Use the newly-added "dahdi_span_assignments" "unmatched" operation. * Now the "dahdi_auto_assign_compat" script only runs "dahdi_registration" if there are no "unmatched" Astribanks. * This prevents the race in fully configured systems. The race may still exist on partially-configured systems.
