puppet-master[12610]: You have configuration parameter $classfile specified in [puppetd], which is a deprecated section. I'm assuming you meant [agent] Renamed config sections (and binaries) in puppet >=2.6 brings this warning in /var/log/messages. My sugesstion for later use: the init scripts should renamed also.
Created attachment 248435 [details, diff] rename sections, add option 'certname'
Fixed.
