How to start multiple Fabric8 containers at boot time on Linux?

Issue

• Fuse 6.x is supplied with sample init scripts or unit files to start a single container at boot time. How can multiple containers be started? For example, how can a parent container and all its associated child containers be started in a single operation?
• After a machine restart, Fuse Fabric starts up but our child containers will not start automatically. How how do we get our child containers to start automatically?
