Dear bug triager. This bug was created since a commit was marked with DOCIMPACT.
Your project "openstack/bareon" is set up so that we directly report the documentation bugs against it. If this needs changing, the docimpact-group option needs to be added for the project. You can ask the OpenStack infra team (#openstack-infra on freenode) for help if you need to.
