Ok, let's get into this #Ansible thing. Fresh #Debian #Linux, which Ansible playbooks (that is what they are called, right?) should I use?

I want to remove password of root, disable ssh login for root, create a user and add it to sudoers list (#sudo without password), add ssh key, disable login with password, set hostname, configure some DNS server on 127.0.0.1 and get the box to reboot.

Other useful things welcome.
