        Change the backend storage driver from devicemapper to AUFS.
        The device mapper storage engine is known to be problematic, and AUFS
        is not enabled by default in Ubuntu. This will install AUFS support and
        swap the backend. **NOTE** It is not recommended to reconfigure this post
        deployment. You may incur dataloss.
