cc_install_hotplug:
description: |
This module will install the udev rules to enable hotplug if supported by
the datasource and enabled in the user-data. The udev rules will be
installed as ``/etc/udev/rules.d/90-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
refresh the instance metadata from the datasource, detect the device in
the updated metadata, then apply the updated network configuration.
Udev rules are installed while cloud-init is running, which means that
devices which are added during boot might not be configured. To work
around this limitation, one can wait until cloud-init has completed
before hotplugging devices.
Currently supported datasources: Openstack, EC2
