Those are about grub and the kernel. If you think grubby suffers from a
bug when updating LILO installations, grubby is part of the "mkinitrd"
package.

Well, if you have reason to believe that grubby does something wrong,
find out what it does wrong. Run it manually, it has a man page, too.
And /boot/boot.b must exist when it is specified in lilo.conf. Do you
say that grubby deletes that file by accident?

And if you're really fed up with grubby, you could modify new-kernel-pkg
to execute your own lilo-update script/program instead of grubby.
