It seems reasonable to conclude that one could set up / as a RAID1 on the first pair of disks, and bootstrap far enough to include swap, /var, and /usr from a RAID10 stretched across a full-disk set. It just sounds somewhat tricky to set it all up, is all, so if someone has grokked out a recipe ... :) -danny
