Call me dumb, but why would someone use "eject" on a non-physically
ejectable device such as a memory stick ? I use it on CDs, I've used
it on Sun floppy drives, but USB memory stick ??? After the umount,
I just have to pull it from the plug and that's all. I don't catch
what an eject command can bring me on top of that :-/
