Right.  Here's the issue; it doesn't work on the original disk (as it
shouldn't) on the entire BSD slice but...

It DOES on the "clone"!

It ALSO does on the "a" partition of the clone.

This implies that gpart screwed up the partitioning, but THAT leaves
open how and why the original partitioning (which is defined here
https://wiki.freebsd.org/FreeBSD/arm/Raspberry%20Pi%202%20image) works
at all, since that's what I'm doing -- and yet it gives the results as
above (and no boot when I'm done.)
