Comment 1 for bug 2060751

```
class ManilaGaneshaCharm(charms_openstack.charm.HAOpenStackCharm,
                         charms_openstack.plugins.BaseOpenStackCephCharm,
                         ):
    release = 'rocky'
    name = 'ganesha'
    python_version = 3
    source_config_key = 'openstack-origin'
    packages = [
        'ceph-common',
        'python3-cephfs',
        'python3-rados',
        'nfs-ganesha-ceph',
        'manila-share',
        'python3-manila',
    ]
```

basically the above makes charmhelpers (https://github.com/openstack/charms.openstack/blob/018b72d734223db274b59f524b7887d8153cdb6d/charms_openstack/charm/classes.py#L215) populate workload_version in the juju status with the ceph-common version instead of one of the manila-specific packages version
