   9 ##      <p>
  10 ##      This template creates a user domain, types, and
  11 ##      rules for the user's tty, pty, home directories,
  12 ##      tmp, and tmpfs files.
  13 ##      </p>
  14 ##      <p>
  15 ##      This generally should not be used, rather the
  16 ##      unpriv_user_template or admin_user_template should
  17 ##      be used.
  18 ##      </p>
