The info is taken from CentOS which is usefull
when bind (provides named) and dnsmasq are both
installed and one may fail to start:

By defining 'listen-address' in the global dnsmasq.conf file we
prevent other instances of dnsmasq from using the global config as we
will get an error that the address is already in use. Instead we pass
'local-service' when we start the main dnsmasq instance which will
listen on the loopback address as well as any other local
subnets. This will allow the main dnsmasq instance to play nice with
other instances we might start for network-manager, libvirt, lxc...

Dnsmasq functions as DHCP and DNS servers by default and listens on all
interfaces. This conflicts with other DHCP or DNS servers already on
the network and corrupts DNS configuration on Windows systems.
We noticed that after installing docker, the Linux system became a
magnet for DNS requests coming from Windows systems. Dnsmasq is a
dependency for lxc which is recommended for docker.
Windows periodically broadcasts DHCPInform and DHCP servers reply with
DHCPAck. If the DHCPAck from the Linux target reaches the Windows
system first, Windows changes its DNS server IP to the Linux system
running dnsmasq. Dnsmasq ends up forwarding the DNS requests to the
official DNS server and replies back the answer to the original
requestor. The Linux system transparently becomes a DNS proxy on the
subnet.

* Make dbus a PACKAGECONFIG option and remove dnsmasq-dbus recipe
* Set LICENSE to correctly indicate choice of licenses
* Set SUMMARY instead of DESCRIPTION
