Of the debconf dialog ? Yep, i need to rework it, suggestions are welcome.

Yes and no. It allows to tranform the vmlinux file in a auto-bootable and
compressed vmlinuz file, which the firmware then knows how to boot.

Nope, more exactly, yaboot replaced it ways back then, altough it is used on
arches where yaboot doesn't work (prep and pegasos), or for easy distribution
(kernel+initrd -> one file only) and netbooting (since IBM rs6k apparently
can't read the yaboot.conf or tftp get different files.

Nah, that would be grub2, but it lacks a bit of maturity, or the fabled
prom-libc/yaboot2 combo.
