+dnl The OVS initscripts never make an empty database (one without even an
+dnl Open_vSwitch record) visible to ovs-vswitchd, but hand-rolled scripts
+dnl sometimes do.  At one point, "ovs-vswitchd --detach" would never detach
+dnl and use 100% CPU if this happened, so this test checks for regression.
