Julia Kreger 69187bae3f Provide an ability to disable serial console injection
By default, we attempt to inject a serial console, which may, or may not
be needed, for example, Centos Stream 9 cloud images already configure
a console setting, and repeating it just might be undesirable and cause
workload performance degredation if the kernel or an application has to
report anything to a console.

This change generally results in original console entries being preserved,
which might actually be a bug and get fixed in a latter patch.

Generally, users of dib *should* likely be specific what they want to do
with their console setting, and without setting the new
DIB_BOOTLOADER_USE_SERIAL_CONSOLE paramter to false, the default will
be adhered to, and any pre-existing serial console entries will *not* be
de-duplicated from the base image. That too is *likely* a bug, but a
harder one to fix.

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 that are responsible for building disk images. They are also used extensively to build images for testing OpenStack itself, particularly with nodepool. Platforms supported include Ubuntu, CentOS, RHEL and Fedora.
