I presume that is possible (you're right that, since it's a block
device under OS control, you should be able to tell it which way to
behave). My fairly quick reading of the docs doesn't tell me that it
works this way, though, so I have to assume it doesn't. (It's not
the question of what it could do, but what it actually does, that's
the important one for implementors.)
