Yeah, don't get me wrong, I think Docker is great. I remember when I first heard about it thinking "Finally, something approaching jails functionality in Linux." Of course, I know it's a different level of abstraction and all that. My comments were more directed at the underlying Linux infrastructure Docker uses. Granted, I may well be wrong, it's been a long time since I was seriously in Linux land (i.e. not just a mindless day-to-day user), I'm not current with hard technicalities so it's totally possible that I'm being unjust to LXC. I'm happy to hear about plans for different backends, the jails one would be awesome if it comes to fruition.
