Ubuntu 15.04 will come up with its own file system
Canonical has introduced LXCFS, its own file system for LXC, which will be released with the next version of Ubuntu 15.04 Vivid Verbet.
It will be available with Apache 2.0 license and it will provide the possibility to view Linux virtual containers and CPU or memory, among other information.
In addition, it will allow to boot LXC on Ubuntu in processes with and without privileges, thus adding some level of security.
If you want to try it before the next Ubuntu version is released, you can download the code on GitHub.
