[Dnsmasq-discuss] how to avoid reading /etc/dnsmasq.conf

[Kristian Lein-Mathisen]

I see, that makes sense. I had a feeling that I'd had this working before.
Thanks Simon for the clarification.

I often find config files to be clunky to work with. If you are writing a
script, for example, it's easier to skip the config file entirely and apply
all options in the script itself. Also, if you don't have root access, you
may not be able to modify /etc/dnsmasq.conf.

Thanks!
