"""
Thanks to libcontainer, Docker out of the box can now manipulate namespaces, control groups, capabilities, apparmor profiles, network interfaces and firewalling rules – all in a consistent and predictable way, and without depending on LXC or any other userland package. This drastically reduces the number of moving parts, and insulates Docker from the side-effects introduced across versions and distributions of LXC. In fact, libcontainer delivered such a boost to stability that we decided to make it the default.

Thanks, but that's still not saying what was flaky.
In fact it doesn't point out any problems with LXC at all except a general hand-wavy statement about stability (which sounds a lot like NIH-justification).
I was looking for actual problems - since I've never encountered any with LXC/Docker, I'd be interested.
Not because I don't take your argument at face value, but because I'm interested to know what exactly they consider flaky.
