                <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.</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>
