NAME
       mke2fs.conf - Configuration file for mke2fs

DESCRIPTION
       mke2fs.conf  is  the configuration file for mke2fs(8).  It controls the
       default parameters used by mke2fs(8) when it is creating ext2  or  ext3
       filesystems.

       The  mke2fs.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
       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 charac-
       ter).

       The following stanzas are used in the mke2fs.conf file.  They  will  be
       described in more detail in future sections of this document.

       [defaults]
              Contains  relations  which define the default parameters used by
              mke2fs(8).  In general, these defaults may be  overridden  by  a
              definition  in the fs_types stanza, or by an command-line option
              provided by the user.

       [fs_types]
              Contains relations which define defaults that should be used for
              specific filesystem types.  The filesystem type can be specified
              explicitly using the -T option to mke2fs(8).  If  no  filesystem
              type is specified, mke2fs(8) will use the filesystem type floppy
              if the filesystem size is less than or equal to 3 megabytes.  If
              the  filesystem size is greater than 3 but less than or equal to
              512 megabytes, mke2fs(8) will use the filesystem small.   Other-
              wise, mke2fs(8) will use the default filesystem type default.

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

       base_features
              This  relation  specifies  the  filesystems  features  which are
              enabled in newly created filesystems.  It may be  overridden  by
              the base_features relation found in the filesystem-type-specific
              subsection of the [fs_types] stanza.

       default_features
              This relation specifies a set of features that should  be  added
              or removed to the features listed in the base_features relation.
              It may be overridden by the filesystem-specific default_features
              in  the  filesystem-type subsection of [fs_types], and by the -O
              command-line option to mke2fs(8).

       blocksize
              This relation specifies the default blocksize if the  user  does
              not specify a blocksize on the command line, and the filesystem-
              type specific section of the configuration file does not specify
              a blocksize.

       inode_ratio
              This relation specifies the default inode ratio if the user does
              not specify one on the command  line,  and  the  filesystem-type
              specific  section  of  the configuration file does not specify a
              default inode ratio.

       inode_size
              This relation specifies the default inode size if the user  does
              not  specify  one  on  the command line, and the filesystem-type
              specific section of the configuration file does  not  specify  a
              default inode size.

THE [fs_types] STANZA
       Each  tag in the [fs_types] stanza names a filesystem type which can be
       specified via the -T option to mke2fs(8).  The value of the  tag  is  a
       subsection  where  the relations in that subsection define the defaults
       for that filesystem type. For example:

       [fs_types]
            small = {
                 blocksize = 1024
                 inode_ratio = 4096
            }
            floppy = {
                 blocksize = 1024
            }

       For each filesystem type, the  following  tags  may  be  used  in  that
       fs_type's subsection:

       base_features
              This  relation specifies the features which are enabled for this
              filesystem type.

       default_features
              This relation specifies set of features which should be  enabled
              or  disabled  to  the features listed in the base_features rela-
              tion.  It may be overridden by the  -O  command-line  option  to
              mke2fs(8).

       blocksize
              This  relation  specifies the default blocksize if the user does
              not specify a blocksize on the command line.

       inode_ratio
              This relation specifies the default inode ratio if the user does
              not specify one on the command line.

       inode_size
              This  relation specifies the default inode size if the user does
              not specify one on the command line.
