I'm trying to find out how dnsmasq got on my CentOS 7 system, since I use 
BIND for DNS. I'm guessing it was part of a base group that Anaconda 
installs for all systems.

Red Hat has this answered on this page but the answer is only available to 
subscribers. I'm guessing this kind of content will be available to us once 
the new free subscription thing starts.
