                <para><filename>systemd-fsck@.service</filename> is a
                service responsible for file system checks. It is
                instantiated for each device that requires a file
                system
                check. <filename>systemd-fsck-root.service</filename> is
                responsible for file system checks on the root
                file system. The root file system check is performed
                before the other file systems. Either service is enabled
                at boot if passno in <filename>/etc/fstab</filename> for
                the file system is set to a value greater than zero.</para>

                <para><filename>systemd-fsck</filename> will
                forward file system checking progress to the
                console. If a file system check fails, emergency mode
                is activated, by isolating to
                <filename>emergency.target</filename>.</para>
