# Add inotify watch to track changes on this device.

# and useless events whenever the device opened for read-write is closed.
# The best would be to generate the event directly in the tool changing
# relevant information so only relevant events will be processed
# (like creating a filesystem, changing filesystem label etc.).

# But let's use this until we have something better...
