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 filesystem 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> </refsect1> <refsect1> <title>Kernel Command Line</title> <para><filename>systemd-fsck</filename> understands one kernel command line parameter:</para> <variablelist class='kernel-commandline-options'> <varlistentry> <term><varname>fsck.mode=</varname></term> <listitem><para>One of <literal>auto</literal>, <literal>force</literal>, <literal>skip</literal>.
