Comment 20 for bug 1912844

So I would think it to be odd to not have `ovs-vsctl` available if you're running Open vSwitch, but as you point out we have no way of knowing how or where other distributions or image builders would think to put the binary, so that is a fair point.

I'm leaning towards specifically checking for '/sys/class/net/ovs-system' and '/sys/class/net/ovs-netdev' for now and then add new datapath types as we become aware of them and/or add the optional runtime detection with dependency on external binary when needed.
