Fwiw, this is not uncommon.  I see this commonly and haven't invested debug 
effort since it is harmless.  I suspect there is a race condition.

Yeah, the node correctly releases its dynamic DHCP range address and then
grabs its proper IP address - this is from its first discovery attempt.

At that point I could use rpower to power it off, so it all seems to be
working correctly!

All the best,
