Comment 1 for bug 1431217

Additional comment.

In this context it would be useful to have indications on how to retrieve the HOT version currently supported by the heat service you are using.
According to https://blueprints.launchpad.net/heat/+spec/heat-build-info the engineers have implemented a new feature that corresponds to command "heat build-info" for that purpose.

The funny thing is that, at the time of writing, the command does not retrieve useful information because when I submit that it returns:

api "revision": "unknown"
engine "revision": "unknown"

This behavior is due to the implementation that gets these two pieces of information from a configuration file and currently they are both set to "unknown" https://review.openstack.org/#/c/55434/11/etc/heat/heat.conf.sample
