Ian Wienand 6c8d7432a6 Set grub device in /etc/default/grub Currently we run grub-mkconfig then go and edit the generated output in /boot/grub/grub.cfg to override the "root=" arguments to our label. If another element like project-config's finalise.d/99-fix-grub-timeout then goes and re-runs grub2-install, it overwrites these changes. Grub has GRUB_DEVICE which should override the root device. Let's try using this. Maybe it wasn't around at the time, this code is more-or-less unchanged from I7d83bb2b359e7a8c3858eca04c96e35cf4e1fe9e Change-Id: Ibaaa81124098f3c6febe48e455d3e1cd0a5f1761		2017-01-16 09:53:56 +00:00

Image building tools for OpenStack
==================================

``diskimage-builder`` is a flexible suite of components for building a
wide-range of disk images, filesystem images and ramdisk images for
use with OpenStack.

This repository has the core functionality for building such images,
both virtual and bare metal.  Images are composed using `elements`;
while fundamental elements are provided here, individual projects have
the flexibility to customise the image build with their own elements.

For example::

  $ DIB_RELEASE=trusty disk-image-create -o ubuntu-trusty.qcow2 vm ubuntu

will create a bootable Ubuntu Trusty based ``qcow2`` image.

``diskimage-builder`` is useful to anyone looking to produce
customised images for deployment into clouds.  These tools are the
components of `TripleO <https://wiki.openstack.org/wiki/TripleO>`__
that are responsible for building disk images.  They are also used
extensively to build images for testing OpenStack itself, particularly
with `nodepool
<http://docs.openstack.org/infra/system-config/nodepool.html>`__.
Platforms supported include Ubuntu, CentOS, RHEL and Fedora.

Full documentation, the source of which is in ``doc/source/``, is
published at:
