Audit-policy configuration capability has been intoduced in https://gitlab.com/sylva-projects/sylva-elements/helm-charts/sylva-capi-cluster/-/merge_requests/245 to address https://gitlab.com/sylva-projects/sylva-core/-/work_items/738 It was maybe functional at that time, but now it does not work any more, since the `/etc/rancher/rke2/audit-policy.yaml` file is not referenced in `/etc/rancher/rke2/config.yaml` We should add a `/etc/rancher/rke2/config.yaml.d/audit.yaml` file that contains the required configuration: `audit-policy-file: /etc/rancher/rke2/audit-policy.yaml`
