This might have been discussed a few years ago, but things have changed.
I'm talking about patches like this one (I'm not the author):
http://developer.osdl.org/dev/fumount/#kernel1
The current situation requires a way to forcibly unmount removable
media. Consider the following (real) scenario. Someone has a box with
hald + dbus + ivman to support "supermounting" the CDROM drive. He has
to install a 2 CD application using Wine for example, but the setup
application prevents normal unmounting of the first one. Then he goes on
and pushes the button to eject the CD, lazy-unmounting the media. The
kernel goes mad and all attempts to load the second CD fail (the kernel
hasn't got rid of the first fs).
If there was anything like a real forced unmounting, things would have
worked well, as on MS Windows itself.
As far as I can see, there is no other sane way to solve such problems.
So, what's keeping such patches from making their way into the
mainstream kernel? All (but maybe I haven't searched enough) arguments
against such a feature that I've seen by now just say "it's not needed",
"it's not worth it" and so on, and many of them refer to network mounts.
P.S.: I'm not saying lazy unmounting should be replaced. They both make
sense, depending on the scenario.
