27 # Add inotify watch to track changes on this device.
28 # Using the watch rule is not optimal - it generates a lot of spurious
29 # and useless events whenever the device opened for read-write is closed.
30 # The best would be to generete the event directly in the tool changing
31 # relevant information so only relevant events will be processed
32 # (like creating a filesystem, changing filesystem label etc.).
34 # But let's use this until we have something better...
