Yes, thanks a lot for the pointers.  It looks like one of the options I
was thinking of, except that I guess I would have to hardcode partition
names instead of using dt properties.

Let's see if I can get around to writing something similar.  But I will
have to get myself another test board first..  The one I have is in use,
and mounted in way that makes console access almost impossible.  Not good
for testing anything that might fail.

That's correct. I am mainly wanting LEDE to work properly regardless of
which partition it is installed in.
