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. Also adds an
    ``os_release`` variable in the same file, with a default value of
    ``8-stream`` when ``os_distribution`` is ``centos`` or ``focal`` when
    ``os_distribution`` is ``ubuntu``.
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.
