Changes

==== Cobbler ====

[https://www.linkedin.com/in/michaeldehaan Michael DeHaan] originally wrote Cobbler, then worked at Puppet Labs (to bring Cobbler and Puppet more in line), and finally started and led the Ansible project, until it was bought by RedHat. The Cobbler project is now led by James Cammarata, who works for Ansible, Inc. In short, you can use both, but Cobbler is not 'better' than Ansible. Ansible literally grew out of Cobbler's early roots.
