Hi Thomas

I'm using the openstack puppet modules to handle the config files in
out production environment.
Since neutron-server is not running on the same host as the metadata
agent, neutron.conf does not have an auth_url entry at all (which for
that case is not necessar).

That's probably why it's then overwritten with the default, (from the
templates file) which makes the neutron-metadata-agent unusable until
the next puppet run.

To conclude, yes it's happening in a working, not broken environment.
Setting the auth_url value in neutron.conf to avoid a change in
metadata_agent.ini seems to be a workaround (did not yet test this), but
I don't think this should be the solution.

Cheers,

Benedikt
