bootstrap a freebsd 9.2 host with ansible. it requires a password for the root user to be set for which it will prompt you (-k). you must use the paramiko transport to allow password based login. based on https://gist.github.com/illenseer/6390361

gistfile1.yml

# run this with ansible-playbook -i ansible_hosts bootstrap.yml -k -c paramiko
- hosts: jails_host
  gather_facts: false
  remote_user: root
  tasks:
  - name: install pkgng
    raw: "pkg_info | grep -v 'pkg-' > /dev/null ; if $? pkg_add -r pkg; rehash ; pkg2ng; echo 'WITH_PKGNG=yes' >> /etc/make.conf; echo 'packagesite: http://pkgbeta.freebsd.org/freebsd%3A9%3Ax86%3A64/latest' >> /usr/local/etc/pkg.conf; pkg update ; pkg upgrade -y"
  - name: install python27
    raw: "pkg install -y python27"
  - name: add ansible ssh-key
    authorized_key: user=root key="{{ item }}"
    with_file:
        - ~/.ssh/identity.pub

Here's a couple of other tricks that may be useful:
