  51     <para><filename>systemd-ask-password-console.service</filename> is
  52     a system service that queries the user for system passwords (such
  53     as hard disk encryption keys and SSL certificate passphrases) on
  54     the console. It is intended to be used during boot to ensure
  55     proper handling of passwords necessary for boot.
  56     <filename>systemd-ask-password-wall.service</filename> is a system
  57     service that informs all logged in users for system passwords via
  58     <citerefentry project='man-pages'><refentrytitle>wall</refentrytitle><manvolnum>1</manvolnum></citerefentry>.
  59     It is intended to be used after boot to ensure that users are
  60     properly notified.</para>

  69     with either the <command>--watch --console</command> or
