Can't register a node from a new template on a downstream cluster about rke

Never mind, the fault was that I mounted /var/lib/docker with the noexec option...

Now I have another problem where the kubelet container can't reserve ephemeral-storage, but it's not likely that it's related to RKE so I'm closing this. Sorry to bother.

If anyone wonders - the second error was actually because of a misconfigured /var/lib/kubelet/config.yaml (didn't quote the keys).
This is a working config.yaml for example:
