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

  78     developer documentation</ulink> for more information about the
  79     system password logic.</para>

  81     <para>Note that these services invoke
  82     <citerefentry><refentrytitle>systemd-tty-ask-password-agent</refentrytitle><manvolnum>1</manvolnum></citerefentry>
  83     with either the <command>--watch --console</command> or
