Right now hosts templates are named:

• hosts.redhat.tmpl
• hosts.ubuntu.tmpl

As the code is written such that it calls:
tpl_fn_name = cloud.get_template_filename("hosts.%s" %
(cloud.distro.name))

This will only work for the 'ubuntu' distro.

Hi, I am not sure if this is alrady addressed in the fix, but if you mark distro as "rhel" in /etc/cloud/cloud.cfg:
[...]
system_info:
distro: rhel
[...]

and enable update_etc_hosts module (which is enabled by default), you get:

2013-01-24 16:15:37,362 - cloud.py[WARNING]: No template found at /etc/cloud/templates/hosts.rhel.tmpl for template named hosts.rhel
2013-01-24 16:15:37,362 - util.py[WARNING]: Running update_etc_hosts (<module 'cloudinit.config.cc_update_etc_hosts' from '/usr/lib/python2.6/site-packages/cloudinit/config/cc_update_etc_hosts.pyc'>) failed

as there is no hosts.redhat.tmpl.

When I do
ln -s /etc/cloud/templates/hosts.redhat.tmpl /etc/cloud/templates/hosts.rhel.tmpl

and re-run update_etc_hosts, then it works properly

Yes Tomas, that is correct. This fix addresses that specific problem.

Your workaround is the appropriate workaround until this fix is released.
