That's true. But besides the recent conversion of the HP9000/00 code to
use bootinfo, not much has changed during the last 5 years.

cannot be used by the kernel, but it doesn't break the bootloader<->kernel
interface the hard way.

when I'm talking to journalists I just say "programmer" or something like that.
