<title>Description</title>
<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>

<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>. Controls the
mode of operation. The default is
<literal>auto</literal>, and ensures
that file system checks are done when
the file system checker deems them
necessary. <literal>force</literal>
unconditionally results in full file
system checks. <literal>skip</literal>
skips any file system
checks.</para></listitem>

<term><varname>fsck.repair=</varname></term>
<listitem><para>One of

<literal>yes</literal>,
<literal>no</literal>. Controls the
mode of operation. The default is <literal>
preen</literal>, and will automatically repair
problems that can be safely fixed. <literal>yes
</literal> will answer yes to all questions by
fsck and <literal>no</literal> will answer no to
all questions.
