      Previously, {product-title} clusters that were installed on AWS using 4.1 boot images were not able to scale up. This issue occurred because two systemd units, configured from Ignition then rendered and launched by the MCO during the initial boot of a new machine, have a dependency on the application Afterburn. Because {product-title} 4.1 boot images do not contain Afterburn, this issue prevented new nodes from being able to join the cluster. Now, systemd units contain an additional check for Afterburn along with fallback code that does not rely on the presence of Afterburn.
