| Changes to `.cluster` configuration for Kubernetes components will not take effect until the Kubernetes cluster is [upgraded]({{< relref "../../kubernetes-guides/upgrading-kubernetes" >}}) and the components are restarted - either manually or via a reboot. |

There was a problem hiding this comment.
I think we might need more careful wording here.
There are two types of components configured in .cluster section:
- control plane components running as static pods (API server, controller manager and scheduler) - changes to these components are applied immediately on the fly
- other settings which in fact update bootstrap manifests - manifests themselves, CNI, kube-proxy configuration - these are not applied automatically, only missing resources are created, but existing ones are not updated (and never removed) - these require a Kubernetes upgrade to be applied

Why? (reasoning)
It is not currently clear that editing the
clusterpart of the machine config also requires these extra steps before the components will be running with the new config.Acceptance
