+# Add inotify watch to track changes on this device.
+# Using the watch rule is not optimal - it generates a lot of spurious
+# and useless events whenever the device opened for read-write is closed.
+# The best would be to generete 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...
