Where is that functionality implemented? I couldn't find it. Does the
kernel that automatically on PPC64? I know too litte about that
architecture.

Well, I thought first of it. But since the '--append' parameter is not
generic, this makes no sense.

Maybe it would make sense to change the command line handling in
general to be global and not image specific, but first I need to
understand how that works on PPC64 ... (and probably others).
