Clark Boylan 3294aecca2 Properly set grub2 root device when using efi
We've noticed that centos8 arm64 images have a root devices of
/dev/mapper/loop7p3 which make sense within a dib image build context
but not at boot time. Dib intends to use labels to set the root device
but when efi is used we end up running grub2-mkconfig against the efi
grub config path before we configure grub to use labels.

Fix this by running grub2-mkconfig after its configuration is set.
This should avoid confusion and complicated paths through the scripts
that configure this for us. We then copy the resulting config to the efi
specific grub.cfg location for platforms that have it.

There is also a small refactoring that is done to try and make the ~3
boot variants more clear:

 1) Booting with legacy bios
 2) Booting with uefi without a signed shim that directly calls grub
 3) Booting with uefi and a signed shim that calls grub

Options 1 and 2 share the /boot/grub*/grub.cfg file. Option 3 needs its
grub.cfg to live alongside distro specific efi target.

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=bionic disk-image-create -o ubuntu-bionic.qcow2 vm ubuntu

will create a bootable Ubuntu Bionic 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
<https://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:

* https://docs.openstack.org/diskimage-builder/latest/
