systemd-fsckd.service, systemd-fsckd.socket, systemd-fsckd - File system check
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.
receives messages about file system check progress from
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.
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.
systemd-fsckd passes the following messages to the theme:
Progress update, sent as a plymouth update message:
the current number of devices being checked
the current minimum percentage of all devices
being checking (float, from 0 to 100)
a translated message ready to be displayed by
the plymouth theme displaying the data above. It can be overridden by themes
Cancel message, sent as a traditional plymouth message:
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.
The following options are understood:
Print a short help text and exit.
Print a short version string and exit.
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.
