AT_BANNER([ovs-vswitchd])
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.
AT_SETUP([ovs-vswitchd detaches correctly with empty db])
