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.
