           e2fsck.conf  is  the configuration file for e2fsck(8).  It controls the
           default behavior of  e2fsck(8)  while  it  is  checking  ext2  or  ext3
           The  e2fsck.conf  file uses an INI-style format.  Stanzas, or top-level
           sections, are delimited by square braces: [ ].   Within  each  section,
           each  line  defines  a  relation, which assigns tags to values, or to a
           subsection, which contains further relations or subsections.  An  exam-
           ple  of  the  INI-style  format used by this configuration file follows
                     tag1 = value_a
                     tag1 = value_b
                     tag2 = value_c
                [section 2]
                     tag3 = {
                          subtag1 = subtag_value_a
                          subtag1 = subtag_value_b
                          subtag2 = subtag_value_c
                     tag1 = value_d
                     tag2 = value_e
           Comments are delimited by a semicolon (';') or a hash  ('#')  character
           at  the beginning of the comment, and are terminated by the end of line
           Tags and values must be quoted using  double  quotes  if  they  contain
           spaces.  Within a quoted string, the standard backslash interpretations
           apply: "\n" (for the newline character), "\t" (for the tab  character),
           "\b" (for the backspace character), and "\\" (for the backslash charac-
           The following stanzas are used in the e2fsck.conf file.  They  will  be
           described in more detail in future sections of this document.
                  This   stanza  contains  general  configuration  parameters  for
                  e2fsck's behavior.
                  This stanza allows the administrator to reconfigure  how  e2fsck
                  handles various filesystem inconsistencies.
                  This  stanza  controls  when  e2fsck will attempt to use scratch
                  files to reduce the need for memory.
                  the  situation  where the system clock is incorrectly set at the
                  time when e2fsck is run.
                  Historically this was usually due to some  distributions  having
                  buggy  init  scripts  and/or  installers  that  didn't correctly
                  detect this case and take appropriate countermeasures.  However,
                  it's still possible, despite the best efforts of init script and
                  installer authors to not be able to  detect  this  misconfigura-
                  tion,  usually  due  to  a buggy or misconfigured virtualization
                  manager or the installer not having access  to  a  network  time
                  server during the installation process.  So by default, we allow
                  the superblock times to be fudged by up to 24 hours.   This  can
                  be disabled by setting accept_time_fudge to the boolean value of
                  false.  This setting defaults to true.
                  The e2fsck(8) program has some heuristics that assume  that  the
                  system clock is correct.  In addition, many system programs make
                  similar assumptions.  For example, the UUID library  depends  on
                  time  not going backwards in order for it to be able to make its
                  guarantees about issuing universally unique ID's.  Systems  with
                  broken  system clocks, are well, broken.  However, broken system
                  clocks, particularly in embedded systems, do exist.  E2fsck will
                  attempt  to  use  heuristics to determine if the time can not be
                  trusted; and to skip time-based checks if this is true.  If this
                  boolean  is set to true, then e2fsck will always assume that the
                  system clock can not be trusted.
                  This boolean relation controls whether  or  not  e2fsck(8)  will
                  offer to clear the test_fs flag if the ext4 filesystem is avail-
                  able on the system.  It defaults to true.
                  This boolean relation  controls  whether  or  not  the  interval
                  between  filesystem  checks  (either  based on time or number of
                  mounts) should be doubled if the system is running  on  battery.
                  This setting defaults to true.
                  When  e2fsck(8)  repacks a indexed directory, reserve the speci-
                  fied percentage of empty space in each leaf nodes so that a  few
                  new entries can be added to the directory without splitting leaf
                  nodes, so that the average fill  ratio  of  directories  can  be
                  maintained  at  a  higher,  more efficient level.  This relation
                  defaults to 20 percent.

    THE [problems] STANZA

           Each tag in the [problems] stanza names a problem code specified with a
           leading  "0x"  followed  by  six hex digits.  The value of the tag is a
           subsection where the relations in that subsection override the  default
           treatment of that particular problem code.
                  when e2fsck is running in preen mode.
           no_ok  This boolean relation overrides the default behavior determining
                  whether or not the filesystem will be marked as inconsistent  if
                  the user declines to fix the reported problem.
                  This  boolean  relation overrides whether the default answer for
                  this problem (or question) should be "no".
                  This boolean relation overrides the default behavior controlling
                  whether  or  not  the  description  for  this filesystem problem
                  should be suppressed when e2fsck is running in preen mode.
                  This boolean relation overrides the default behavior controlling
                  whether  or  not  the  description  for  this filesystem problem
                  should be suppressed when e2fsck is run with the -n option.

    THE [scratch_files] STANZA

           The following relations are defined in the [scratch_files] stanza.
                  If the directory named by this relation exists and is writeable,
                  then  e2fsck will attempt to use this directory to store scratch
                  files instead of using in-memory data structures.
                  If this relation is set, then in-memory data structures be  used
                  if  the  number  of directories in the filesystem are fewer than
                  amount specified.
                  This relation controls whether or not the scratch file directory
                  is  used  instead  of  an in-memory data structure for directory
                  information.  It defaults to true.
           icount This relation controls whether or not the scratch file directory
                  is  used  instead  of  an in-memory data structure when tracking
                  inode counts.  It defaults to true.


           The following recipe will prevent e2fsck from aborting during the  boot
           process when a filesystem contains orphaned files.  (Of course, this is
           not always a good idea, since critical files that are  needed  for  the
           security  of  the  system  could  potentially end up in lost+found, and
           starting the system without first having a system  administrator  check
           things out may be dangerous.)
