/*
* mkfs.minix.c - make a linux (minix) file-system.
*
* (C) 1991 Linus Torvalds. This file may be redistributed as per
* the Linux copyright.
*/
/*
* DD.MM.YY
*
* 24.11.91 - Time began. Used the fsck sources to get started.
*
* 25.11.91 - Corrected some bugs. Added support for ".badblocks"
* The algorithm for ".badblocks" is a bit weird, but
* it should work. Oh, well.
*
* 25.01.92 - Added the -l option for getting the list of bad blocks
* out of a named file. (Dave Rivers, rivers@ponds.uucp)
*
* 28.02.92 - Added %-information when using -c.
*
* 28.02.93 - Added support for other namelengths than the original
* 14 characters so that I can test the new kernel routines..
*
* 09.10.93 - Make exit status conform to that required by fsutil
* (Rik Faith, faith@cs.unc.edu)
*
* 31.10.93 - Added inode request feature, for backup floppies: use
* 32 inodes, for a news partition use more.
* (Scott Heavner, sdh@po.cwru.edu)
*
* 03.01.94 - Added support for file system valid flag.
* (Dr. Wettstein, greg%wind.uucp@plains.nodak.edu)
*
* 30.10.94 - Added support for v2 filesystem
* (Andreas Schwab, schwab@issan.informatik.uni-dortmund.de)
*
* 09.11.94 - Added test to prevent overwrite of mounted fs adapted
* from Theodore Ts'o's (tytso@athena.mit.edu) mke2fs
* program. (Daniel Quinlan, quinlan@yggdrasil.com)
*
* 03.20.95 - Clear first 512 bytes of filesystem to make certain that
* the filesystem is not misidentified as a MS-DOS FAT filesystem.
* (Daniel Quinlan, quinlan@yggdrasil.com)
*
* 02.07.96 - Added small patch from Russell King to make the program a
* good deal more portable (janl@math.uio.no)
*
* 06.29.11 - Overall cleanups for util-linux and v3 support
* Davidlohr Bueso <dave@gnu.org>
*
* Usage: mkfs [-c | -l filename ] [-12v3] [-nXX] [-iXX] device [size-in-blocks]
*
* -c for readablility checking (SLOW!)
* -l for getting a list of bad blocks from a file.
* -n for namelength (currently the kernel only uses 14 or 30)
* -i for number of inodes
* -1 for v1 filesystem
* -2,-v for v2 filesystem
* -3 for v3 filesystem
*
* The device may be a block device or a image of one, but this isn't
* enforced (but it's not much fun on a character device :-).
