But seriously, when you need a /boot partition, it is only as useful as the rest of the system.
This is true. In this particular case, I wanted the boot partition to survive if the data disks survived. Kinda annoying to have the data disks survive, but have to rebuild the system because the / or the /boot paritions didn't survive. With 500GB drives, an extra 200MB partition hardly matters, while it will save me a lot of headaches should one or two drives fail (assuming it's the right drives, and the data partition is still there).
I didn't think you were duplicating / across all 4 in the layout you proposed. Thus the questions about putting /boot there. If your /boot doesn't work you can always boot the install cd in rescue mode to fix it but there's not much you can do about a missing /.
