Comment 9 for bug 1423153

I notice this is marked "Fix Released" but I can't determine the nature of the fix; when deploying mysql on the serverstack environment using the openstack-charm-testing framework, the mysql root password wasn't stored in the usual /var/lib/mysql/mysql.passwd location, I couldn't find it in relations, and all the online documentation I could find still references that specific file.

What is the nature of the fix that was released? Where should this fix be available? (e.g., should I have expected the openstack-charm-testing environment to have picked up this fix automatically?)

Thanks
