When you use 'grub-install /dev/sda' you are telling GRUB to install into the boot sector of /dev/sda and put core.img into a post-MBR portion of the disk. The boot block knows where the first sector of core.img is and core.img can search for and find the configuration. I don't think GRUB uses system device names to do any of this when booting the OS. > Anyway there seems to be some sort of trick to using grub-install. For some > people it works fine. For others (myself included) it doesn't. No tricks needed as far as I am concerned. You maybe have to realise that --boot-directory needs a grub.cfg as one of its contents but, as we hope roberto has discovered, update-grub takes care of that. -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of "unsubscribe".
