When we enable techpreview and we create a MachineOsConfig resource for the worker pool, the controller pod and the os-builder pods panic.
    

pre-merge https://github.com/openshift/machine-config-operator/pull/4327
    

Always
    

    1. enable techpreview
oc patch featuregate cluster --type=merge -p '{"spec":{"featureSet": "TechPreviewNoUpgrade"}}'


    2. Create a MachineOsConfig resource for the worker pool


 oc create -f - << EOF                                                     
apiVersion: machineconfiguration.openshift.io/v1alpha1
kind: MachineOSConfig
metadata:
  name: worker
spec:
  machineConfigPool:
    name: worker
  buildInputs:
    imageBuilder:
      imageBuilderType: PodImageBuilder
    baseImagePullSecret:
      name: $(oc get secret -n openshift-config pull-secret -o json | jq "del(.metadata.namespace, .metadata.creationTimestamp, .metadata.resourceVersion, .metadata.uid, .metadata.name)" | jq '.metadata.name="pull-copy"' | oc -n openshift-machine-config-operator create -f - &> /dev/null; echo -n "pull-copy")
    renderedImagePushSecret:
      name: $(oc get -n openshift-machine-config-operator sa builder -ojsonpath='{.secrets[0].name}')
    renderedImagePushspec: "image-registry.openshift-image-registry.svc:5000/openshift-machine-config-operator/ocb-image:latest"
EOF


    

The build pod is triggered, and once it finishes the os-builder pod and the controller pod panic
    

No pod should panic
