This is the baremetal (IE: real hardware) element.

Does the following:

 * extracts the kernel and initial ramdisk of the built image.
Create a new baremetal element Rather than using a script to mount the image using nbd to extract the kernel and ramdisk, make a new element called baremetal, which contains a cleanup.d script that will copy them out to <image name>.{vmlinuz,initrd}.

baremetal element: Enable stable interface names By default most cloud images have disabled the udev rules which give us stable network interface names. While this is a reasonable default for something like EC2 (the target for these images) this is very bad behavour on bare metal and can cause a "musical NICs" situation to occur where on reboot the NIC names get swapped. In this commit we re-enable stable interface naming by removing the dev nulled rules softlink and installing the biosdevname package. Once this is done interface names should again show up as em1, em2 instead of the old eth0, eth1. We also remove some the common, statically configured eth0 config files on some distributions. Equivalent files (if needed) may be auto-generated by using the dhcp-all-interfaces element. Change-Id: Idd67977342719e2f295e2fa2c0ed6cfa8602171a 2014-02-07 21:18:28 +00:00			`Does the following:`
