Just to be clear: dhcp wasn't running at the point I am talking about.
NM did delete the nameserver information in /etc/resolv.conf .
I saw then that one can go to NM's Manage Connections
and specify the nameservers one wants to use.
When I did that the nameservers remained in /etc/resolv.conf

So it seems to me reasonable to say that NM _was_ editing a config file
without my knowledge.
