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