Pertaining to my previous email, I noticed that when I upgraded my Ubuntu
14.04's default 3.13 kernel to 3.15 using instructions at
http://ubuntuhandbook.org/index.php/2014/06/install-upgrade-linux-kernel-3-15,
it lacks AUFS support causing Docker to use VFS.
I need to test the same system as yours with 3.15 kernel and AUFS support.
What are you using?
