This adds a new concept of network "zones", which are little more than bridge devices that are automatically managed by nspawn: when the first container referencing a bridge is started, the bridge device is created, when the last container referencing it is removed the bridge device is removed again. Besides this logic --network-zone= is pretty much identical to --network-bridge=. The usecase for this is to make it easy to run multiple related containers (think MySQL in one and Apache in another) in a common, named virtual Ethernet broadcast zone, that only exists as long as one of them is running, and fully automatically managed otherwise.
