Subject:Re: [openstack-dev] [keystone][tripleo][ansible][puppet][all] changing default token format

I totally agree with communicating this the best we can. I'm adding the operator list to this thread to increase visibility.

If there are any other methods folks think of for getting the word out, outside of what we've already done (release notes, email threads, etc.), please let me know. I'd be happy to drive those communications.

My email was not to tell you to stop.I was just letting you know that
your change does not affect the puppet modules because we define our
default as UUID.  It was just as a heads up to others on this email
that this change should not affect anyone consuming the puppet modules
because our default is still UUID and will be even after keystone's
default changes.

Thanks,
-Alex
