The rootfs of the containers use large disk space and is defaulted to
/var/lib/lxc. It's desirable to configure an alternative rootfs directory on a
partition with large enough free space to hold the rootfs.
The rootfs of a container is hard-linked to the lxc cache when created by lxc
templates. Therefore both have to reside on the same partition and the lxc
cache shall be configurable as well as the rootfs directory.
The lxc-ubuntu template is patched by lxc-host role to use the configured lxc
cache folder. This patch should be removed once the updated upstream lxc with
support of configuring the cache path goes mainstream.
To confgiure these parameters, set the following variables in global_overrides
of openstack_user_config.yml:
- lxc_container_directory, defaults to /var/lib/lxc
- lxc_container_cache_path, defaults to /var/cache/lxc
