DNS resolvers
From: http://serverfault.com/questions/478534/how-is-dns-lookup-configured-for-osx-mountain-lion
"Looks like the XML plist file storing the DNS servers is /Library/Preferences/SystemConfiguration/preferences.plist"
OS X doesn't use /etc/resolv.conf which is just annoying.
Boot options
