     In an ansible-based deployment, we **don't** clone the premix repo to /var/data/config. Instead, we clone it somewhere local, and then use the playbook to launch the stack, including the creation of ceph shared storage at /var/data/config. The necessary files are then **copied** from the cloned repo into `/var/data/config`, so that they can be altered by the user, backed up, etc. This separation of code from config makes it easier for users to pull down updates to the premix repo, without having to worry about merge conflicts etc for the files they've manually changed during deployment.
