NAME
e2fsck.conf - Configuration file for e2fsck

DESCRIPTION
e2fsck.conf is the configuration file for e2fsck(8). It controls the default parameters used by e2fsck(8) when it is creating ext2 or ext3 filesystems.

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 example of the INI-style format used by this configuration file follows below:

    [section1]
        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 character.

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 character).

The following stanzas are used in the e2fsck.conf file. They will be described in more detail in future sections of this document.

[options]
    This stanza contains general configuration parameters for e2fsck's behavior. [problems] This stanza allows the administrator to reconfigure how e2fsck handles various filesystem inconsistencies.

THE [options] STANZA
The following relations are defined in the [options] stanza.

allow_cancellation
    If this relation is set to a boolean value of true, then if the user interrupts e2fsck using ^C, and the filesystem is not explicitly flagged as containing errors, e2fsck will exit with an exit status of 0 instead of 32. This setting defaults to false.

defer_check_on_battery
    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. It defaults to true.

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.

Note that inappropriate settings in this stanza may cause e2fsck to behave incorrectly, or even crash. Most system administrators should not be making changes to this section without referring to source code.

Within each problem code's subsection, the following tags may be used:

description
    This relation allows the message which is printed when this filesystem inconsistency is detected to be overridden.

preen_ok
    This boolean relation overrides the default behavior controlling whether this filesystem problem should be automatically fixed 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.

no_default
    This boolean relation overrides whether the default answer for this problem (or question) should be "no".

preen_nomessage
    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.

no_nomsg
    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.

EXAMPLES
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.)

    [problems]
        0x040002 = {
            preen_ok = true
            description = "@u @i %i. "
        }
