   An update that has one optional fix can now be installed.

Description:


   By default Docker uses loopback mounted "devices" to store docker images
   and metadata. This default storage configuration (100 GB for image
   storage) leads to a rather lengthy start up phase of docker when initially
   launched.

   When docker is enabled by default, such as in the Amazon Container Service
   images for SUSE Linux Enterprise, the slow start up time of docker upon
   instance creation provides a sub optimal user experience. Additionally
   other services that depend on docker being operational may time out.

   The script and systemd unit file in the docker-img-store-setup package
   address the problem described above. The script creates a 100 GB device
   file that is then formatted with btrfs. The mounted device allows docker
   to use the btrfs storage driver and the start up process is very fast.
