features:
- To ensure the deployment system remains clean the Ansible execution environment is
contained within a virtual environment. The virtual environment is created at
"/opt/ansible-runtime" and the "ansible.*" CLI commands are linked within /usr/local/bin
to ensure there is no interruption in the deployer workflow.
deprecations:
- Installation of Ansible on the root system, outside of a virtual environment, will
no longer be supported.
