So at this point I'm still left wondering what I'm supposed to do instead of the grub thing so that the boot information is correctly mirrored on to the other RAID1 device.In other words, what *should* the wiki say instead of having the incorrect set of instructions that refer to grub?
see here http://www.syslinux.org/wiki/index.php/EXTLINUX about RAID-1 ctrl-f .. "raid" -- дамјан
