  11 You just created an Ubuntu container (release=precise, arch=i386, variant=default)
  12 
  13 To enable sshd, run: apt-get install openssh-server
  14 
  15 For security reason, container images ship without user accounts
  16 and without a root password.
  17 
  18 Use lxc-attach or chroot directly into the rootfs to set a root password
  19 or create user accounts.
