Alex Schultz 02e5353a9f Allow ELEMENTS_DIR to be configurable
Prior to version 2.0.0 of diskimage-builder, the elements dir was hard
coded as 'elements' in dib-lint which allowed dib-lint to be consumed by
other projects (instack-undercloud). The 2.0.0 release has changed this
path and it is not overridable so that the other projects can still use
dib-lint. This change makes ELEMENTS_DIR and LIB_DIR check for an
existing environment variable so that dib-lint can be consumed outside
of the diskimage-builder project.

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 <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
<http://docs.openstack.org/infra/system-config/nodepool.html>`__.
Platforms supported include Ubuntu, CentOS, RHEL and Fedora.
