At the service level / terraform provider, the default for additional worker pools is RHEL 8 even if the cluster / default worker pool was created specifying RHCOS. I think this is slightly confusing behavior of the provider / ROKS service, and the module should probably be coded so that it force the users' of the module to "think" - by explicitly requiring to always set the operating system on the worker pool inputs and not using an empty default.
