Note that you can use runC (the underlying runtime for Docker) in a similar way to rkt (except you also don't have to deal with images if you don't want to -- runC just runs a rootfs). And runC doesn't have a daemon as well, and is the canonical implementation of the Open Container Initiative runtime specification. We're also working on ocid, which is a way to run kubernetes purely on an OCI stack (no Docker required). Though, shoutouts to the rkt guys. They really are awesome and have been helping out a lot in the OCI effort.
