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

                <para>See the <ulink
                url="http://www.freedesktop.org/wiki/Software/systemd/PasswordAgents">
                developer documentation</ulink> for more information
                about the system password logic.</para>
