Fearless enough to run a helper program? I've written a C program that
makes dnsmasq work. The program sets up a file alteration monitor on
/etc/resolv.conf. Whenever that file changes, the code ensures that
"127.0.0.1" is the first nameserver listed there and passes the upstream
server addresses to dnsmasq. A short script in
/etc/NetworkManager/dispatcher.d makes sure this program is running
whenever a network interface is started. I believe it's pretty
bulletproof, and most of its configuration can be overridden from the
command line.
