Ian Wienand 99f10f9380 rockylinux : create machine-id early
Somewhere between the upstream container
rockylinux/rockylinux:8.6.20220515 and the latest release, systemd
started to be pre-installed in the container.

With <= 20220515 installing the kernel-core package would end up
pulling in systemd.  As part of the systemd package installation, the
/etc/machine-id file is created and populated.

The kernel package post-install steps install the kernel with
/bin/kernel-install; this is responsible for copying the kernel
binaries into /boot.  It does this based on the machine-id, and it
seems its failure case with a blank machine-id is to simply skip
copying the kernels into /boot.  To compound this problem, it seems
our bootloader installation doesn't notice that we don't have a kernel
installed, so we end up building an unbootable image.

Testing is/was showing us this; but as rocky is non-voting and this
occured at a random time (rather than in response to a dib change) I
think it slipped by us.

To work around this, create the machine-id early in the container.  We
already have paths that remove the machine-id from final images.

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:
