Antoine Musso 23be09ce35 debian: cloud hostname ignored by Jessie 
5af25b5f fixed the hostname of Debian images to "debian" since a lack of
hostname definition set the hostname to "(None)".

It has been done by introducing /etc/cloud/cloud.cfg.d/01_hostname.cfg
with content:

  hostname: debian

Review supposed the hostname would be overriden by cloud meta-data. That
might have stand true for Wheezy but it is not the case for Jessie.

cloud-init 0.7.6 ignores cloud metadata whenever "hostname" or "fqdn"
are set in a config file. Roughly:

    # no fqdn set, get fqdn from cloud
    # get hostname from cfg if available otherwise cloud
    fqdn = cloud.get_hostname(fqdn=True)
    if "hostname" in cfg:
        # hashar: set from config file NOT cloud
        hostname = cfg['hostname']
    else:
        # fallback to cloud
        hostname = cloud.get_hostname()

Relevant code is
https://github.com/number5/cloud-init/blob/0.7.6/cloudinit/util.py#L839-L860

Only inject "hostname: debian" for the Wheezy release.

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.
