We have deployed Openstack-Ansible in a test environment and we were wondering what the recommended repository branch is to deploy in a production environment that will be integrated with a separate Ceph cluster.

1. We are thinking about pinning to the stable/zed. Is that recommended over the master branch? 
2. Are bugs ironed out on both master and stable/zed with the same cadence?
3. Additionally, is Debian 11 a better alternative than Ubuntu 22 for target hosts?

We noticed Ubuntu 22.04 support was added recently, whereas Debian 11 has been supported for quite some time now which leads us to believe its stability/integration could be more mature at this point?

Any suggestions will be appreciated.

Thank you,
