In case you use docker-machine to manage a local VirtualBox-based machines the solution is as simple as for boot2docker:

docker-machine upgrade MACHINE_NAME

It asks docker-machine to download the latest boot2docker.iso and place it as a new root filesystem in the upgraded VM.

By the way, the VirtualBox-backed docker machine has its root filesystem readonly. That mean it's not possible for any manual update survive the machine reboot. That was a surprise for me.
