Comment 18 for bug 993298

OK, I managed to send a dbus signal to set specific dns for a specific domain but this signal went to the initial dnsmasq started when system booted up.
So the dnsmasq started by the wifi sharing connection has no dbus interface and it doesn't read the /etc/hosts. It has totally static hardcoded configuration.

The only way to overcome this issue was the very dirty solution of putting dnsmasq in a wrapper script to remove the --no-hosts parameter :(
