Yeah, this particular variant doesn't.
Other variants, using a kernel-supplied varying hash prefix (which could
be exposed through some file named hashprefix within /sys) could.
What I don't understand is why you entertain the idea of doing so. It
would be like our current approach in that it would be impossible to
put firmware in a file that would load. So why not stick with the
current approach?
