Grub doesn't, I'm fairly sure, support raid on /boot, but that does not mean you can't use it with mirroring, I do. Make your mirror in which ever way you like, then install grub onto all partitions involved in the mirror. But, here's the key, you can re-map grub devices to real devices. Here is the interesting bit from a hacked about systemimager script for network installing of boxes (they have 2 hard drives, and all partitions are mirrored over the drives) chroot /a /sbin/grub --batch --no-floppy <<EOT device (hd0) /dev/hda root (hd0,0) setup (hd0) device (hd0) /dev/hdc root (hd0,0) setup (hd0) quit EOT -- Mike Williams
