# The OpenShift image has the NVMe hostid and hostnqn hardcoded, so it ends up | ||
# being the same in all the control plane nodes, which is problematic. | ||
# This MachineConfig fixes this issue by recreating both files when the hostid | ||
# doesn't match the system-uuid of the machine it is running on. | ||

Sorry, I just spotted this now, but should the role be worker? I think our other machineConfig specify master nodes, and that works in our small environments where nodes are both.
