The job retrieves the image from the given URL, provisions the image on the device at IP address ``DEVICE_IP``, and prints the distribution-specific information on the provisioned device:

+Data specified in the ``provision_data`` section varies on device types. For example, to provision server images on a MAAS device, the ``distro`` field should be used to indicate the system version. The following YAML file defines a job that provisions the Ubuntu 22.04 LTS (Jammy Jellyfish) server install image on a MAAS device and prints the information about its processors and network interface configurations:
