Now I just need to find out what is "GPT patition label", a "GUID",
and "structure creation"!  I will read glabel(8) and see if that
clears it up for me.

Okay, although I am a bit surprised to hear that a GPTID refers to a
partition.  I'm using FreeNAS and I thought I instructed the zpool to
consist entirely of unpatitioned disks.  I gather that FreeNAS is,
somewhere in the process, creating partitions which triggers
"structure creation" which creates unique GPTIDs.

Thank you again,

Chris
