      As an OpenShift cluster admin, I want my small-medium sized cluster to be fully functional even when the default TuneD profiles (openshift, openshift-node, openshift-control-plane) are not applied by NTO.

      This means that I need the sysctl setting 

      vm.max_map_count=262144

      so that OpenShift logging (ElasticSearch) works by default. I also need 

      net.ipv4.conf.all.arp_announce=2

      set.

      I understand that disabling NTO may reduce the performance and scalability of my cluster.
