+ <title>Description</title>
+
+ <para><filename>systemd-fsckd.service</filename> is a service responsible
+ for receiving file system check progress, and communicating some
+ consolidated data to console and plymouth (if running). It also handles
+ possible check cancellations.</para>
+
+ <para><command>systemd-fsckd</command> receives messages about file
+ system check progress from <command>systemd-fsck</command> through a
+ UNIX domain socket. It can display the progress of the least advanced
+ fsck as well as the total number of devices being checked in parallel
+ to the console. It will also send progress messages to plymouth.
+ Both the raw data and translated messages are sent, so compiled
+ plymouth themes can use the raw data to display custom messages, and
+ scripted themes, not supporting i18n, can display the translated
+ versions.</para>
+
+ <para><command>systemd-fsckd</command> will instruct plymouth to grab
+ Control+C keypresses. When the key is pressed, running checks will be
+ terminated. It will also cancel any newly connected fsck instances for
+ the lifetime of <filename>systemd-fsckd</filename>.</para>
+ </refsect1>
+
+ <refsect1>
+ <title>Protocol for communication with plymouth</title>
+
+ <para><filename>systemd-fsckd</filename> passes the
+ following messages to the theme:</para>
+
+ <para>Progress update, sent as a plymouth update message:
+ <literal>fsckd:&lt;num_devices&gt;:&lt;progress&gt;:&lt;string&gt;</literal>

+ </varlistentry>
+ <varlistentry>

+ <listitem><para>a translated string ready to be displayed

+ <title>Exit status</title>
