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