| Nope, doesn't work. Apparently even dd goes through the vfs layer.
It goes through the vfs layer, when you give it a file that's sitting
on the vfs layer, e.g., dd if=/usr/tmp/somefile.tgz. If you gave it a
raw device then it would act accordingly. Unfortunately I have no idea
how to find out where your file is actually sitting on the raw disk
device and if you knew that whether or not you could use dd to get at
it.
