I found the item I was looking for:


"(From the mdadm 2.6.8 man-page) When creating partition-based arrays
using mdadm and version-1.x superblocks, the partition type should be
set to 0xDA (non fs-data). This type selection allows for greater
precision since using any other type [RAID auto-detect (0xFD) or a
GNU/Linux partition (0x83)], might create problems in the event of array
recovery through a live cdrom."

Since I'm not building an array from previously established partitions
this does not apply.

Thanks for confirming what I just found.  I love it when a plan comes
