The udev rules will be installed as ``/etc/udev/rules.d/10-cloud-init-hook-hotplug.rules``. When hotplug is enabled, newly added network devices will be added to the system by cloud-init. After udev detects the event, cloud-init will referesh the instance metadata from the datasource, detect the device in the updated metadata, then apply the updated network configuration.
