Ian Wienand df3ad26f58 yum-minimal: strip env vars in chroot calls
This showed up with dnf in containers when TMPDIR was set; dnf started
trying to write to this directory while in the chroot.

We already do stripping like this in run_in_target -- but this is a
bit of a unique place because it's actually setting up the initial
chroot so the target doesn't actually exist yet; so we just hard-code
it in place here.

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
<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:
