OK. The results are in --
Using the RC(8) declarations I listed above work not only in RELENG_8,
but also in RELENG_9. I just performed an install from the 9.0 CD I
downloaded from freebsd.org on 12-12-14. Everything (both as STATIC,
and as DHCP) worked as expected/anticipated.

Is this still worth a PR(1)?

Best wishes, and thanks again, to everyone that took the time to help!
