Previously, on Ubuntu 16.04, I felt betrayed when an Ubuntu update installed
dnsmasq package, configured it, and gave it precedence over my own super-stable, ultra-fast, and own-configured BIND DNS server. It exactly felt as if Ubuntu hacked my workstation.
Since I happened to be working as a system admin, this was extremely unacceptable. This was a freak-out call. This is when you go to troubleshoot a problem and in one of your steps you use
nslookup and you get stunned to see the
lo interface replying to you. PANIC
Is there a way to not only fix this issue, but also guarantee that
/etc/resolv.conf will be tamper proof?
