features:
  - The container cache preparation process now allows ``copy-on-write`` to be
    set as the ``lxc_container_backing_method`` when the
    ``lxc_container_backing_store`` is set to ``lvm``. When this is set a base
    container will be created using a name of the form
    `<linux-distribution>`-`distribution-release>`-`<host-cpu-architecture>`.
    The container will be stopped as it is not used for anything except to be
    a backing store for all other containers which will be based on a snapshot
    of the base container.
  - When using copy-on-write backing stores for containers, the base container
    name may be set using the variable ``lxc_container_base_name`` which
    defaults to
    `<linux-distribution>`-`distribution-release>`-`<host-cpu-architecture>`.
