Ben Nemec 088f0eb7ac Move busybox binary-dep to ramdisk element
Busybox should be installed and managed from the ramdisk element,
since that is common to all elements that need busybox.  In
addition, we do not want busybox installed when building Dracut
ramdisks, so it can't be in the deploy-* elements.

This is the ramdisk element.

Almost any user building a ramdisk will want to include this in their build, as it triggers many of the vital functionality from the basic diskimage-builder libraries (such as init script aggregation, busybox population, etc).

An example of when one might want to use this toolchain to build a ramdisk would be the initial deployment of baremetal nodes in a TripleO setup. Various tools and scripts need to be injected into a ramdisk that will fetch and apply a machine image to local disks. That tooling/scripting customisation can be easily applied in a repeatable and automatable way, using this element.

NOTE: ramdisks require 1GB minimum memory on the machines they are booting.

See the top-level README.md of the project, for more information about the mechanisms available to a ramdisk element.
