No. Brand new machine, pulled it out of the box and racked it. NOTHING on the 
internal SSDs. Made an md RAID 0 on the raw disks - /dev/sda /dev/sdb. No 
partitions, nothing. However, when I bring it up, fdisk shows an MBR with no 
partitions. I can, however, mount /dev/md127p3 as /mnt/sysimage, and all is there.

Did I need to make a single partition, on each drive, and then make the RAID 1 
out of *those*? I don't think I need to have /boot not on a RAID.
