Merge lp:~ubuntu-on-ec2/livecd-rootfs/cpc into lp:livecd-rootfs

[Dan Watkins]

This merge proposal contains the changes required to use livecd-rootfs to build our base cloud images. We are currently using it in a PPA for building the vivid cloud images using the Launchpad buildds.

(Resubmitting because LP seems to have got unhappy about diffs/conflicts)

[Steve Langasek (vorlon)]

This MP still shows a conflict over the live-build/ubuntu-core/hooks/99zz-check-uid-gid.chroot file, and wants to move the existing file aside and replace it. Could you please resolve this conflict (probably requires a fresh branch and a new MP)?

review: Needs Fixing
