Hi Darryl, Imho your digging too deep. GRUB may be a great tool, but for your purpose it's overdone. Lilo will be able to perform exactly what you need, and it will perform well. I see no trouble with remote upgrades, from that point of view substituting GRUB with Lilo is no different than substituting for example one email client with another (unless there are license problems, but those aren't an issue here). If you really want to use GRUB, then I think you should contact the GRUB maintainers for this issue (and perhaps a few others from the archives as well;).
