Ben Nemec 5bed4a6d5e Run dhcp-interface@.service after network.target When we configure dhcp interfaces before network.target has run, network.target will try to bring up those interfaces a second time after our service does so. This causes two issues - first, the network target will always fail because it can't bring up an interface that is already up, and second, when configuring interfaces that don't actually have an available DHCP server it will result in a five minute delay waiting for DHCP on those interfaces. This will also cause the network target to fail and is an unnecessary delay. By moving the dhcp-interface service to run after the network target we avoid both of these problems. network.target will still bring up the interfaces on subsequent boots. This could result in the five minute delay happening on reboots, but the expected use case for interfaces without DHCP is that they would be configured statically on initial deployment so this should be a minor issue. The dhcp-interface service is also configured to run before the network-online target so that services which depend on the network actually being available will not race the DHCP process. A snippet from /var/log/messages on a node with this patch applied is included in the bug to demonstrate the behavior described above.

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.
