Some people think that writing a new kernel would be easy.  %^)

The trouble is coming up with a convenient method.  LILO stores a list
of blocks.  GRUB reads filesystems.  GRUB is better in the long run,
but harder to implement.

Nowadays, I'm using syslinux because LILO is such a pain to get right
and GRUB doesn't (last time I checked) like the DOC.  I just got done
working out the kinks in etherboot so it will run with a DOC.  I guess
GRUB is next.
