+    <title>Description</title>
+
+    <para><filename>systemd-fsck@.service</filename>, <filename>systemd-fsck-root.service</filename>, and
+    <filename>systemd-fsck-usr.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> and <filename>systemd-fsck-usr.service</filename> are
+    responsible for file system checks on the root and /usr file system, respectively, but only if the root
+    filesystem was not checked in the initrd. <filename>systemd-fsck@.service</filename> is used for all
+    other file systems and for the root file system in the initrd.</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, but only if it is also configured to be
+    mounted at boot (i.e. without <literal>noauto</literal> option). 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>fsck.<replaceable>type</replaceable></filename>). These checkers will decide if
+    the filesystem should actually be checked based on the time since
+    last check, number of mounts, unclean unmount, etc.</para>
+
+    <para><filename>systemd-fsck-root.service</filename> and <filename>systemd-fsck-usr.service</filename>
+    will activate <filename>reboot.target</filename> if <filename>fsck</filename> returns the "System
+    should reboot" condition, or <filename>emergency.target</filename> if <filename>fsck</filename>
+    returns the "Filesystem errors left uncorrected" condition.</para>
+
+    <para><filename>systemd-fsck@.service</filename> will fail if
+    <filename>fsck</filename> returns with either "System should reboot"
+    or "Filesystem errors left uncorrected" conditions. For filesystems
+    listed in <filename>/etc/fstab</filename> without <literal>nofail</literal>
+    or <literal>noauto</literal> options, <literal>local-fs.target</literal>
+    will then activate <filename>emergency.target</filename>.</para>
