Idempotent role
---------------

The role is idempotent. For example, if Poudriere is configured to build packages for two architectures

.. code-block:: yaml

   poudriere_pkg_arch: [amd64, arm]

there should be no changes reported when the playbook is run repeatedly with the same data

.. code-block:: yaml
