RuncDeprecated

[DanielFroehlich]

After the latest update #390 , we see Infor Alert:

The runc OCI runtime has been deprecated and support will be removed in a future release. Migrate to crun before upgrading to a future OpenShift release. See https://docs.redhat.com/en/documentation/openshift_container_platform/latest/html/machine_configuration/machine-configs-custom#config-container-runtime_machine-configs-custom for migration steps.

Thanks, I would add it to the "special" tasks for next patch day.

What do you think?

[DanielFroehlich]

fully agree, as this requires reboot of the nodes.
