The current volume.disc.* properties relate only to the physical layout
of the disc as it affect how policy engines like g-v-m or ivman treat
the disc (e.g. mount/unmount it, setting up a VFS-slave for audio etc.),
not the contents of the disc. Detecting content like video (/VIDEO_TS)
or photos (/DCIM) should be done higher up in the stack by policy
