The Machine Config Operator (MCO) manages updates to systemd, CRI-O and Kubelet, the kernel, Network Manager and other system features. It also offers a `MachineConfig` CRD that can write configuration files onto the host (see link:https://github.com/openshift/machine-config-operator#machine-config-operator[machine-config-operator]). Understanding what MCO does and how it interacts with other components is critical to making advanced, system-level changes to an {product-title} cluster. Here are some things you should know about MCO, machine configs, and how they are used:

* Machine configs are processed alphabetically, in lexicographically increasing order, of their name. The render controller uses the first machine config in the list as the base and appends the rest to the base machine config.
