 Unfortunally this is not so easy.
 IMHO it is missing the fdisk / disklabel part (fstype RAID), which is a 
 for creating the raid set and the initial setup of the bootloader for a root 
 And I'm not sure which stripe size I should use for a raid1 set.
 Greg used a formular on how to calculate it in his mail on current-users at
 the end of August 2008:
  ($stripewidth / 2 * ($disks - 1)) == MAXPHYS
 But it looks like that was an example for a raid5 set, so I'm not sure about
 the '($disks - 1)' part and if it applies to a raid1 set too.
