So how exactly does dnsmasq signal readiness if it's run in foreground?
It does neither implement sd_notify nor use D-Bus activation.
So there is no way for systemd to know when it's ready to accept
connections. As a result, daemon, which depend on dnsmasq would be
started immediately once the dnsmasq binary has been spawned.
