  35
  36     <para><filename>systemd-ask-password-console.service</filename> is
  37     a system service that queries the user for system passwords (such
  38     as hard disk encryption keys and SSL certificate passphrases) on
  39     the console. It is intended to be used during boot to ensure
  40     proper handling of passwords necessary for boot.
  41     <filename>systemd-ask-password-wall.service</filename> is a system
  42     service that informs all logged in users for system passwords via
  43     <citerefentry project='man-pages'><refentrytitle>wall</refentrytitle><manvolnum>1</manvolnum></citerefentry>.
  44     It is intended to be used after boot to ensure that users are
  45     properly notified.</para>
