features:
- Add docker-storage-driver parameter to baymodel to
allow user select from the supported drivers. Until
now, only devicemapper was supported. This release
adds support for OverlayFS on Fedora Atomic hosts with
kernel version >= 3.18 (Fedora 22 or higher) resulting
significant performance improvement. To use OverlayFS,
SELinux must be enabled and in enforcing mode on the
physical machine, but must be disabled in the container.
Thus, if you select overlay for docker-storage-driver
SELinux will be disable inside the containers.
