+ * mkfs.minix.c - make a linux (minix) file-system.

+/*
+ * 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 :-).
