That's what I imagined.  I didn't mean to attribute this to the kernel, but
I see that's basically how I wrote it.

I know it's not easy, but if it's the right way then it's the right way.

I don't think anybody's questioning the security of the approach.  I just
get the feeling that you'll get resistance to it.  You might try floating
the idea on the kernel list and see how people react.  I've got my opinion
on how it should work, but I can see that you have to have this data very
early on and it will not be trivial to make it work my way.  Linus may end
up agreeing with you, which would probably help your argument for inclusion
of your patch.  :-)
