rootfs of node is used for volume of pods

[donbowman]

flatcar.raw is ~3G in size, a single partition.
It is in turn used to run the node.
The node in turn uses this for the volume (host, emptydir) of pods. Its not enough.

I think the /var/lib/kubelet needs to be mounted somewhere outside this container, or some provisioner needs to mount things inside it for space (e.g. empty dir type).
