On a hypervisor, binding on link local IPs is undesirable IMHO and that's why I always added a similar ignore to the one you proposed. That said, NTP works well over link local addresses so some folks are probably using it.

Currently it is "too" open on that. I see it trying to bing link local addresses for each of the KVM guests I spawn. They get virtual network devices and due to that ntp sees it tries to bind and fails.
