The mounting can be done automatically just like the kernel does now.

Think of unmounting as flushing all dirty buffers and setting a read-only
flag on the device.

Right. However, most (all?) SCSI removable drives *can* lock the eject
button, so it would be wise to use that feature - and AFAIK, the harddisk
driver will actually do that if you lock the device.

So the only thing needed would be a method to call a unmount/eject action in
the filesystem, instead of the harddisk driver (which will not flush buffers
and set the clean flag).
