According to https://docs.google.com/document/d/1fgP6Kv1D-75e1Ot0Kg-W2qPyxWDp2_CALltlBLuseec/edit#heading=h.ny6l9ud82fxx this seems to be a known condition but it's not clear how to prevent that from happening and therefore ensure installation are working as expected.

The major difference found between /etc/mcs-machine-config-content.json on the OpenShift Container Platform 4 - Control-Plane Node and the rendered-master-${hash} are within the following files.

 - /etc/mco/proxy.env
 - /etc/kubernetes/kubelet-ca.crt

OpenShift Container Platform 4.13.4

Random

1. Install OpenShift Container Platform 4.13.4 on AWS with platform:none, proxy defined and both machineCIDR and machineNetwork.cidr set.

Installation is stuck and will eventually fail as the MachineConfigPool is failing to rollout required MachineConfig for master MachineConfigPool

Installation to work or else provide meaningful error messaging
