The *networking* service, which is actually a legacy init script, is
provided by the *initscripts* package on RHEL and its derivatives. This
service needs to be running in order for the configuration generated by
the *rhel-network* role to be applied to the managed node.
The `network.yml` playbook is used to configure the network interfaces
on a managed node. Currently, it only supports the Red Hat configuration
style (i.e. `/etc/sysconfig/network-scripts/ifcfg-*` files).
