[Linaro-validation] More attempts to deploy to mustang in LAVA

Hi,

I'm still trying to deploy to the disk of a mustang in the LAVA lab (without rewriting the dispatcher). I have something that looks like it should work:

https://github.com/mwhudson/lava-deploy-job/blob/master/job.json

It dd's an Ubuntu cloud image (just a raw image made out of the ubuntu-provided qcow) onto /dev/sda, reboots and tries to run flash kernel to render it bootable. This isn't quite going to work for a couple of reasons, but the failure is confusing to me:

Why doesn't the device reboot between the steps? (I'm also not sure why the networking fails when chrooted but that's separate I think).

CHeers, mwh
