It is instantiated for each device that requires a file system check. systemd-fsck-root.service is responsible for file system checks on the root file system. systemd-fsck will forward file system checking progress to the console. If a file system check fails emergency mode is activated, by isolating to emergency.target. systemd-fsck understands one kernel command line parameter: fsck.mode= One of auto, force, skip. Controls the mode of operation. The default is auto, and ensures that file system checks are done when the file system checker deems them necessary. force unconditionally results in full file system checks. skip skips any file system checks. systemd1, fsck8, systemd-quotacheck.service8
