The very next day, Congress passed the Omnibus Crime Control and Safe Streets Act of 1968, the first federal gun-control law in 30 years. Months later, the Gun Control Act of 1968 amended and enlarged it.

This is exactly the approach that Chef has chosen. They built Omnibus, an automation system which spawns an army of VMs for building platform-specific packages. It works, but it's heavyweight and a big hassle. You need a big build machine for that if you want to have reasonable build time. And be prepared to make 20 cups of coffee.
