I think a kernel as second-stage bootloader is overkill. I think people
should rather work merging the advantages of LILO and those of GRUB, to
get a DECENT bootloader. What I hate most about LILO is the unawareness
of file systems and the ugly menu, what GRUB lacks, is the ability of
passing in "next-time" boot-parameters of lilo -R way - which prevents
many people of switching from LILO to GRUB.

Besides that, it would be really cool if you could just replace a
running kernel by a new one, though I think it would require shutting
down all services prior to that. Still, not going through the BIOS boot
procedure would be an advantage...

Find GRUB at (that is from memory, in case
it's wrong, search for it at
