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.
