targets:
  lxc:
    create-message: |-
      You just created an Ubuntu container (release=artful, arch=amd64, variant=default)

      To enable sshd, run: apt-get install openssh-server

      For security reason, container images ship without user accounts
      and without a root password.

      Use lxc-attach or chroot directly into the rootfs to set a root password
      or create user accounts.
