    domain-ontology-rule: Use private locations for the cache & the journal
    
    GNOME Photos uses private instances of the Tracker 2.x daemons. Using
    the global location for the Tracker cache and the journal can cause
    contention with other instances of Tracker running on the system,
    leading to unknown behaviour.
    
    Therefore, it's better to use private locations for private Tracker
    instances.
