  59                 <para><filename>systemd-fsck@.service</filename> is a
  60                 service responsible for file system checks. It is
  61                 instantiated for each device that requires a file
  62                 system
  63                 check. <filename>systemd-fsck-root.service</filename> is
  64                 responsible for file system checks on the root
  65                 file system. The root file system check is performed
  66                 before the other file systems. Either service is enabled
  67                 at boot if passno in <filename>/etc/fstab</filename> for
  68                 the filesystem is set to a value greater than zero.</para>

  71                 forward file system checking progress to the
  72                 console. If a file system check fails, emergency mode
  73                 is activated, by isolating to
  74                 <filename>emergency.target</filename>.</para>
