   man 5 resolv.conf
Not saying it was smart.
second try was
   rpm -qf /etc/resolv.conf
on the theory that some package ought to own every config file and
have some sort of documentation about the files it owns. Not much of a
theory.

That would have taken me just as long as this process did, since I had
no connection in my brain initially between resolv.conf and ifcfg. I
think if there was an obvious good candidate, we would not be talking
about this, I'd have found my answer right away on my own.

I think Meenoo Shivdasani probably had the best idea, to google the
message I found in my modified /etc/resolv.conf.

best,
Dave
