  64                 is a system service that queries the user for system
  65                 passwords (such as hard disk encryption keys and SSL
  66                 certificate passphrases) on the console. It is
  67                 intended to be used during boot to ensure proper
  68                 handling of passwords necessary for
  69                 boot. <filename>systemd-ask-password-wall.service</filename>
  70                 is a system service that informs all logged in users
  71                 for system passwords via
  72                 <citerefentry><refentrytitle>wall</refentrytitle><manvolnum>1</manvolnum></citerefentry>. It
  73                 is intended to be used after boot to ensure that users
  74                 are properly notified.</para>
