  63
  64     <para><filename>systemd-ask-password-console.service</filename> is
  65     a system service that queries the user for system passwords (such
  66     as hard disk encryption keys and SSL certificate passphrases) on
  67     the console. It is intended to be used during boot to ensure
  68     proper handling of passwords necessary for boot.
  69     <filename>systemd-ask-password-wall.service</filename> is a system
  70     service that informs all logged in users for system passwords via
  71     <citerefentry project='man-pages'><refentrytitle>wall</refentrytitle><manvolnum>1</manvolnum></citerefentry>.
  72     It is intended to be used after boot to ensure that users are
  73     properly notified.</para>

  77     developer documentation</ulink> for more information about the
  78     system password logic.</para>
  79
  80     <para>Note that these services invoke
  81     <citerefentry><refentrytitle>systemd-tty-ask-password-agent</refentrytitle><manvolnum>1</manvolnum></citerefentry>
  82     with either the <command>--watch --console</command> or
