3 # @see http://docs.ansible.com/intro_installation.html#latest-release-via-yum
5 # [NOTE] To fix the "sudo: sorry, you must have a tty to run sudo" issue,
6 # we need to patch /etc/sudoers.
7 # @see http://unix.stackexchange.com/questions/122616/why-do-i-need-a-tty-to-run-sudo-if-i-can-sudo-without-a-password
