Huh? LXD is Canonicals, but I don't think LXC is in any sense a "Canonical" project? (I thought) LXC's primitives are what Docker is actually using. Why would LXC need a registry any more than say Rkt? scp a tarball, or host the tarball on an https endpoint? Done, no?

Docker stopped used LXC stuff a while ago. Sure docker uses Linux namespaces and such, but that has a lot more to do with OpenVZ then LXC. People seem to like LXC because they want to treat containers as 'light weight virtual machines' and run full stack Linux OSes in them with init systems and multiprocesses and such things. However that isn't the direction the industry is moving, which is focusing on containers as simple runtime packaging were you have the absolute minimum needed to run a single application. RKT is interesting because it doesn't depend on a a separate daemon to manage containers. Instead you use the host's systemd daemon to manage containers in a similar way you manage everything else in a system. It simplifies things like managing cgroups and improves reliability.
