+### Cgroup drivers
 
 When systemd is chosen as the init system for a Linux distribution, the init process generates
-and consumes a root cgroup and acts as a cgroup manager. Systemd has a tight integration with
-cgroups and will allocate cgroups per process. It's possible to configure your container
-runtime and the kubelet to use `cgroupfs`. This means that there will then be two different

+Control groups are used to constrain resources that are allocated to processes.
 A single cgroup manager will simplify the view of what resources are being allocated
 and will by default have a more consistent view of the available and in-use resources. When we have
 two managers we end up with two views of those resources. We have seen cases in the field
