Ian Wienand 8c837409b8 Turn down tracing for source-repo cache If you check logs like [1] it's literally thousands of lines of the same thing over-and-over as the git caching happens. It is basically all just noise unless you're debugging it specifically. Up this to tracing level 2 ("-x -x") to see it. Add a note in the help about multiple flags, which has always been intended but not documented. Image builds should continue to run with single "-x", but we could probably greatly increase signal:noise ratio in the logs with a little more judicial use of this to turn down some of the very noisy & repetitive parts.

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.

Full documentation, the source of which is in ``doc/source/``, is
