I think this part of the documentation is ambiguous. I think there are two separate things being mixed up. 1) On a normal running system, there will be a root directory, and off that a /boot directory in which it is convenient to place the vmlinuz and initrd images. This will have a subdirectory called grub, with all the grub stuff in it. The reason for this is so you can have a small partition at the start of a large disk that the BIOS can definately boot from. 2) when you are preparing a root image for another disk you will need to mount its root file system in a convenient place. Confusingly they use /boot as the mount point. If we think this through instead using /mnt as the mount point. Then, say, we have a disk /dev/sda on which we want to install grub, so that it can boot images from it. This disk will be partitioned, and /dev/sda1 will have the root system file image on it so we mount the root filesystem mount /dev/sda1 /mnt grub install --root-directory=/mnt /dev/sda will install the stage 1 grub into the boot sector of /dev/sda, with links in this boot sector to a stage 2 (or stage 1.5) image stored in /mnt/boot/grub -- Alan Chandler http://www.chandlerfamily.org.uk -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
