Redirecting our output through outfilter.py is inherently a bit racy, since the disk-image-create process will exit, and then you might get outfilter.py flushing any remaining output as it closes. On an interactive prompt this might lead to final output overwriting the prompt, etc. This can be a bit confusing when you start running things in a loop. If we save the original fd, then on the exit path close the redirected fd's and wait a little bit for final output (as a result of the close), we get a more consistent output.

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.
