%description
In the transition between docker<=1.9 and docker>=1.10, the image manifest
format has changed. Upon restarting Docker, it will go through a lengthy
migration process. This package allows for the bulk of the migration to be done
while still on docker<=1.9, allowing for minimal-to-no downtime (while
restarting Docker will cause downtime during the migration).

Please run

for the migration to start. This script will source /etc/sysconfig/docker to
ascertain the storage driver and storage options used by Docker. If you wish to
add any extra options, you can specify them as arguments to the script.
