--- features: - | Adds an ``os_distribution`` variable in ``etc/kayobe/globals.yml``, with a default value of ``centos``. The variable can also be set to ``ubuntu``, and sets sensible default values for other variables. upgrade: - | Modifies the default value of ``controller_bootstrap_user``, ``compute_bootstrap_user``, ``seed_bootstrap_user``, ``seed_hypervisor_bootstrap_user`` and ``storage_bootstrap_user`` from using the ``$USER`` environment variable of the Ansible control host to ``os_distribution``. This provides a more predictable default that does not depend on the Ansible execution environment.
