Ian Wienand 53d04d27c6 centos: work around 9-stream BLS issues
Per the bug mentioned upstream, grub2-mkconfig will currently not set
the kernel options for BLS entries prefixed with a machine-id
different to the running system.

This affects the centos element, as the upstream .qcow2 comes with a
pre-existing BLS entry but a blank machine-id.  This only affects
9-stream -- prior releases either don't use BLS or have entries
configured to use a common variable from grubenv which is updated
correctly.

We currently can not end-to-end test this in OpenDev because we run
our functional tests on Ubuntu Focal (they use devstack), whose kernel
can not read the XFS format on the 9-stream .qcow2.  This expands the
functional tests (that run on Debian Buster, with a later kernel) to
add the vm element, so the bootloader path is exercised (this requires
a block-device too).  This at least runs the bootloader install, we
can confirm the kernel options look right from the dumping provided
the logs.

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.
