Take a step back and look at the whole picture.

Your suggestion will override a DHCP-related config item somewhere else.

Yes, it will likely stop the system from over-writing resolv.conf - in 
that, you are correct.

No, it will not satisfy the requirement of the the o.p. which was, I 
quote: "At this point, I am as (or more) interested in pointers 
regarding how to find the answer as I am in the actual answer. Please 
teach me to fish."

What I'm trying to do here is to help the o.p. to find what causes the 
modification of resolv.conf, not how to cover up the issue. It's easy to 
hide the problem, either do what you suggest, or edit away 
make_resolv_conf(). But the underlying cause will remain, and may 
resurface if these changes are undone.
