Do not uninstall non-installed packages
The bootloader element uses the grub-efi-$arch package to remove already
installed packages (for redhat).  The uninstall of a non-installed
package fails with a non-zero exit code on gentoo.  The gentoo base
tarball does not include a bootloader and the grub-efi-$arch package is
only used for uninstalls, so zero out the variable to allow bootable
images to be generated.

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/
