Well, I have RAID1 systems ...

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 ... :)
