After going through the other PR mentioned here, I can understand the need for this change. Since we are proposing to mount /etc/containers this change is needed for that. From the mentioned bug ticket, I can see at present that the controller-manager makes requests to quay.io and not the internal image registry. It seems it doesn't have access to that registry and bringing in this change will enable that as the config.json is read in this way.
