This I am still trying to do, the first pass copied all 350G of /home

It is now /dev/sdh and all labels above it are now wrong. Crazy.
These SSD's all have an OTP serial number. I am tempted to use that
serial number as a label _I_ can control.
When I built and ran a Debian 2 @ HDD RAID1 using mdadm(8), I did not
partiton the HDD's -- I gave mdadm(8) the whole drives.
I don't know if it is a good idea, in fact it exists a special partition
type for RAID array listed in fdisk, I used that for my RAID:

I thought it was mandatory for a RAID to partition drives with this
partition type, am I wrong?
