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