Comment 2 for bug 1510524

Now it looks like this:
- to get communication puppet node -> puppet master we need to know puppet master IP
- documentation in point 5.2.3 tell us that we need to set puppet address in /etc/hosts file
- execute puppet agent
- during puppet work manifest override /etc/hosts and delete our changes with puppet IP
- puppet client ends with error, part of steps cannot be done, agent dont know where puppet server is :)

It works when we have puppet master name in DNS, but now we cannot use /etc/hosts as a source for puppet master IP.
