True. The best available procedure to do this for ACPI bay/dock currently is, AFAIK: 1. Send event when bay/dock "please release" button/lever is pressed. Do *nothing* else. I know bay does this right, maybe dock doesn't. 2. Wait for something to echo 1 >eject or to call the appropriate routine directly, or (if this exists) for an notification from firmware that the user IS disconnecting the device for real. 3. delete the device. This means force-umount, force-close, etc. 4. Tell the hardware to eject. Note that currently (2) and (3) are swapped, as (3) is being done by userspace request, instead of by the kernel. This is something I *don't* like.
Userspace wants to (non-force-)-unmount by itself after (1), so it can stop the eject process if the filesystems cannot be cleanly unmounted. So the force-unmount at (3) ends up being a redundant safety measure at best.
