Make a version-less RHEL element to handle both '7' and '8' DIB_RELEASE. The element usage should align with other elements which operate in the same way such as the Fedora element. Additionally, this patch adds support for RHEL8 that operates with Python 3. As of now, users of diskimage-builder will still be able to use the 'rhel7' element, or migrate to 'rhel' and specify their respective DIB_RELEASE value. * mount the xfs file-system for extraction as read-only. vaguely based on explaination in [1] and the fact we only read the image data into a tar, so can ignore this. XFS (dm-1): Superblock has unknown read-only compatible features (0x4) enabled. * Use the redhat system python as the dib-python version. dib was ahead of it's time making an abstracted python interpreter for system work ;) the system python should work for running the various dib element scripts.

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 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.
