+ <title>Description</title>
+
+ <para><filename>systemd-fsck@.service</filename> and
+ <filename>systemd-fsck-root.service</filename> are services
+ responsible for file system checks. They are instantiated for each
+ device that is configured for file system checking.
+ <filename>systemd-fsck-root.service</filename> is responsible for
+ file system checks on the root file system, but only if the
+ root filesystem was not checked in the initramfs.
+ <filename>systemd-fsck@.service</filename> is used for all other
+ file systems and for the root file system in the initramfs.</para>
+
+ <para>These services are started at boot if
+ <option>passno</option> in <filename>/etc/fstab</filename> for the
+ file system is set to a value greater than zero. The file system
+ check for root is performed before the other file systems. Other
+ file systems may be checked in parallel, except when they are on
+ the same rotating disk.</para>
+
+ <para><filename>systemd-fsck</filename> does not know any details
+ about specific filesystems, and simply executes file system
+ checkers specific to each filesystem type
+ (<filename>/sbin/fsck.*</filename>). This helper will decide if
+ the filesystem should actually be checked based on the time since
+ last check, number of mounts, unclean unmount, etc.</para>
+
+ <para>If a file system check fails for a service without
+ <option>nofail</option>, emergency mode is activated, by isolating
+ to <filename>emergency.target</filename>.</para>

+ 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.

+ checks.</para></listitem>
