The element builds dracut from source on Ubuntu because the Ubuntu dracut package is broken and very old, so it can't be installed properly and causes a number of other issues that are fixed by using a newer version of Dracut. This initial version should work in virtualized environments. Further validation of its suitability for real baremetal deployments will need to be done in the future, but this should be sufficient to enable that work. Regarding Dracut specifically, in order to limit the changes needed in the existing scripts this element continues to use a cut down version of the /init script that we were building for the existing ramdisk. However, instead of running it as pid 0 it is run as a Dracut pre-mount hook. This allows Dracut to set up all of the hardware and system bits, while falling early enough in the Dracut sequence to complete the deployment before Dracut would try to boot off the hard disk. bp tripleo-juno-dracut-ramdisks Change-Id: I144c8993fe040169f440bd4f7a428fdbe3d745cf |

Build Dracut-based ramdisks
This is an alternative to the ramdisk element that uses
Dracut to provide the base system functionality instead of
Busybox.
