--- features: - The container cache preparation process now allows ``overlayfs`` to be set as the ``lxc_container_backing_store``. When this is set a base container will be created using a name of the form ``-`distribution-release>`-``. 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. The ``overlayfs`` backing store is not recommended to be used for production unless the host kernel version is 3.18 or higher.
