Is there a way to do this > with grub? You only need to update stuff for grub once - when installing it. And during installation, it's ok to run it multiple times, once for each component device - not a big deal really. Just like you will partition your disks and install an MBR - once for each disk. After installation, grub does not need to modify boot records - only /boot/grub/menu.lst (whatever) file is updated to reflect your kernels, and this is a normal file (grub will find it by its own, by properly reading the filesystem). /mjt
