vgoyal added a new comment to an issue you are following:
``
Upstream dokcer-storage-setup will continue to have devicemapper as default graph driver.
So for this to work properly on atomic host, we probably require following two options set
in /etc/sysconfig/docker-storage-setup.
STORAGE_DRIVER=overlay2
DOCKER_ROOT_VOLUME=yes
By default, a logical volume will be created which will consume 40% of free space.
Remaining will remain free and can be used for growing either rootfs or docker logical
volume. But growing step is manual and there is no automation.
