Perhaps something like btrfs could work.
By creating your base image in a subvol or individual file you can then snapshot that and mount the snapshot into the container?
additionally it lets you piggy back on the stuff that inktank and openstack are doing with ceph and btrfs
distributed storage with cow images for VMs for your container servers
- shykes 13y agobtrfs is one of the alternatives we plan on supporting. In fact there is already an experimental branch with btrfs support. However, wearing my user / operator hat, if I had to choose I would stick to aufs in production. If I had to switch (and the apparently stupid move by ubuntu to drop it might indeed force me to), I would first try to use more proven code, like lvm or raid/dm. btrfs and overlayfs are neat, promising technology for the future - that place where our production deployments can't go :)
