Release - yoga.  Host OS - Debian 11

I'm looking for an example of how to get NFS working as storage for glance and cinder - both the openstack_user_config.yml stanzas and the NFS server setup (/etc/exports, etc.).

So far I've adapted the stanzas from the openstack_user_config.yml examples.  The shares are mounted and writable (by root) from the glance/cinder containers, but glance keeps on throwing 410 errors.
