Indeed

But there is a slight issue in that if the user has yanked the drive, there
isn't much you can do about it. Short of having precognition so you know in
advance, or modifying all hardware to support locking the drive in, once the
drive is disconnected then you have no options - other than to tell the user
off.
For this reason, the automounter package should provide a command for
the user to "safely remove the devices". Not providing it would suggest
the user that removing the device right away is harmless and is the
normal way.
