RKE2
This flavor uses RKE2 for the kubernetes distribution. By default it configures the cluster with the CIS profile:
Using the generic cis profile will ensure that the cluster passes the CIS benchmark (rke2-cis-1.XX-profile-hardened) associated with the Kubernetes version that RKE2 is running. For example, RKE2 v1.28.XX with the profile: cis will pass the rke2-cis-1.7-profile-hardened in Rancher.
Until this upstream PR is merged, CIS profile enabling will not work for RKE2 versions >= v1.29.
