    cached_fs_rom: diagnosis of delivered ROM sessions
    
    To enable logging of ROM session deliveries, set the "diag" on
    session routes:
    
    <route>
      <service name="ROM" label_prefix="/bin/">
        <child name="cached_fs_rom" diag="yes"/>
      </service>
      …
    <route>
    
    Fix #3772
