Can I partition the drives using '-s MBR', then mirror some of the 
partitions & create '-s BSD' slices inside of those mirrors ? 
Specifically, I would partition each drive into 4 primary partitions, 
/boot, swap, 1 partition to be mirrored & then sliced up as per the 
handbook, & 1 partition to be striped & then sliced up ? I would 
probably mirror /boot as well, if feasible. It seems this might comport 
w/ all of the restrictions & possible meta-data conflicts, but I am 
definitely out of my area, hence the questions. TIA & have a good one.
