That's true. But besides the recent conversion of the HP9000/[34]00 code to

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

In personal conversations with technical people, I call myself a hacker. But
when I'm talking to journalists I just say "programmer" or something like that.
