Lilo on a > 2TB device is risky. It has worked exactly once for me, and
never again. Also, a > 2TB device requires a GPT disk label in order to
not eat the file systems created upon it. Lilo cannot install to a GPT
disk partition last time I tried. It barfed badly.
Work is about to begin (as Peter said) to make grub handle GPT disk
labels, which is necessary for > 2TB block devices. This will allow
