- system-image: collect the deivce.tar.gz
* live-build/ubuntu-core/hooks/09-move-kernel-to-device-tar.binary:
- create a device.tar.gz from the installed kernel/modules and
remove it from the rootfs
* live-build/ubuntu-core/hooks/10-remove-documentation.binary:
- strip documentation
* live-build/ubuntu-core/hooks/11-remove-extra-packages.chroot:
- remove extra packages like libicu52/libqt that are still on the
image because vivid system-image has a dependency on u-d-m which
depends on libqt
* live-build/ubuntu-core/hooks/12-add-docker-user.chroot:
- add a docker user/group into the image (this can go once we have
a hook for this)
