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_types 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.
