SYSTEMD-FSCKD.SERVICE(8)     systemd-fsckd.service    SYSTEMD-FSCKD.SERVICE(8)

NAME
       systemd-fsckd.service, systemd-fsckd.socket, systemd-fsckd - File
       system check progress reporting

SYNOPSIS
       systemd-fsckd.service

       systemd-fsckd.socket

       /lib/systemd/systemd-fsckd

DESCRIPTION
       systemd-fsckd.service 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.

       systemd-fsckd receives messages about file system check progress from
       fsck through an 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.

       systemd-fsckd 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
       systemd-fsckd.

PROTOCOL FOR COMMUNICATION WITH PLYMOUTH
       systemd-fsckd passes the following messages to the theme:

       Progress update, sent as a plymouth update message:
       "fsckd:<num_devices>:<progress>:<string>"

       "<num_devices>"
           the current number of devices being checked (int)

       "<progress>"
           the current minimum percentage of all devices being checking
           (float, from 0 to 100)

       "<string>"
           a translated message ready to be displayed by the plymouth theme
           displaying the data above. It can be overridden by themes
           supporting i18n.

       Cancel message, sent as a traditional plymouth message:
       "fsckd-cancel-msg:<string>"

       "<strings>"
           a translated string ready to be displayed by the plymouth theme
           indicating that Control+C can be used to cancel current checks. It
           can be overridden (matching only "fsckd-cancel-msg" prefix) by
           themes supporting i18n.

OPTIONS
       The following options are understood:

       -h, --help
           Print a short help text and exit.

       --version
           Print a short version string and exit.

EXIT STATUS
       On success, 0 is returned, a non-zero failure code otherwise. Note that
       the daemon stays idle for a while to accept new fsck connections before
       exiting.
