Feature Overview

OCP 4 clusters still maintain pinned boot images. We have numerous clusters installed that have boot media pinned to first boot images as early as 4.1. In the future these boot images may not be certified by the OEM and may fail to boot on updated datacenter or cloud hardware platforms. These "pinned" boot images should be updateable so that customers can avoid this problem and better still scale out nodes with boot media that matches the running cluster version.
