One of our dependencies, Docker, only works with the btrfs storage driver
on Trusty. All other storage drivers for Trusty are DOA on Trusty without
kernel recompiles. CentOS 7 works well with all storage drivers, although
overlayfs is a little flakey when building images because of the yum OVL
plugin. We recommend in the docs to upgrade the kernel to Willy howver
Xenail should work as well.
What comes out of this is a recommendation to use BTRFS as the storage
backend when using Trusty. We should be documenting that anyway.
