But not on /boot or /.  I find this just unfathomable.  What do i do if
the disk containing / dies?
   


if raid is configured properly ... it will still boot ...
if /  is on /dev/hda and /dev/hdc  ... and one of the disk dies
        - yow will still be able to boot
if / is on /dev/hda and /dev/hdc and /dev/hde ... and 2 of the disks dies,
        - you will still be able to boot
if you have 4 disks ... you will always be able to boot 99.99% of the time
without touching the keyboard
        /dev/md0 == /dev/hda + /dev/hdd in raid1 mirror
        /dev/md1 == /dev/hdb + /dev/hdc in raid1 mirror
        /dev/md0 and /dev/md1 is stripped ( raid0 ) for faster reading
        ( but not all systems support it properly - bios and raid config
        problem )
data ( /home ) should always be raid5 across those 4 disks 
	or raid1 .. mirror ... or whatever you want

Paul wants / and /boot on mdo and/or md0. I can do it, but the installer 
can't. Paul wants to be able to take either one drive out and boot. Always.
