Try doing ls -l /etc/resolv.conf, and see if that's the case in CentOS-7 as well. (I don't use NM, so I'm not sure what the case is with it, as the machine I'm using had that change made, if it was needed, long ago. :) ) If it does turn out to be a symlink, copy its information, if you need it, then delete the file, then recreate it. Hope this helps, but I'm not sure. It is a working solution in Fedora. Hi, thanks, it does not show it being a sym link.
