In addition, `node.kubernetes.io/unschedulable:NoSchedule` toleration is added
automatically to DaemonSet Pods. The DaemonSet controller ignores
`unschedulable` Nodes when scheduling DaemonSet Pods. You must enable
`TaintNodesByCondition` to ensure that the default scheduler behaves the same
way and schedules DaemonSet pods on `unschedulable` nodes.

When this feature and `TaintNodesByCondition` are enabled together, if DaemonSet
uses the host network, you must also add the
