anchor.diff:  daemon profiles shipped within the default Tuned CR. The example above uses the
   default `openshift-control-plane` profile to accomplish this.
   ====
  +
  +*Using built-in TuneD profiles*
  +
  +Given the successful rollout of the NTO-managed daemon set, the TuneD operands
  +all manage the same version of the TuneD daemon. To list the built-in TuneD
  +profiles supported by the daemon, query any TuneD pod in the following way:
  +
  +[source,terminal]
  +----
  +$ oc exec $tuned_pod -n openshift-cluster-node-tuning-operator -- find /usr/lib/tuned/ -name tuned.conf -printf '%h\n' | sed 's|^.*/||'
  +----
  +
  +You can use the profile names retrieved by this in your custom tuning specification.
  +
  +.Example: using built-in hpc-compute TuneD profile
  +[source,yaml]
  +----
  +apiVersion: tuned.openshift.io/v1
  +kind: Tuned
  +metadata:
  +  name: openshift-node-hpc-compute
  +  namespace: openshift-cluster-node-tuning-operator
  +spec:
  +  profile:
  +  - data: |
  +      [main]
  +      summary=Custom OpenShift node profile for HPC compute workloads
  +      include=openshift-node,hpc-compute
  +    name: openshift-node-hpc-compute
  +
  +  recommend:
  +  - match:
  +    - label: tuned.openshift.io/openshift-node-hpc-compute
  +    priority: 20
  +    profile: openshift-node-hpc-compute
  +----
  +
  +In addition to the built-in `hpc-compute` profile, the example above includes
  +the `openshift-node` TuneD daemon profile shipped within the default
  +Tuned CR to use OpenShift-specific tuning for compute nodes.
  +
  +// Note the issues with including profiles sharing the same ancestor: see link:https://bugzilla.redhat.com/show_bug.cgi?id=1825882[BZ#1825882]

  The following CR applies custom node-level tuning for
  {product-title} nodes with label
  `tuned.openshift.io/ingress-node-label` set to any value.
  As an administrator, use the following command to create a custom Tuned CR.
