- * rm_overwrite --
- *	Overwrite the file 3 times with varying bit patterns.
- *
- * This is an expensive way to keep people from recovering files from your
- * non-snapshotted FFS filesystems using fsdb(8).  Really.  No more.  Only
- * regular files are deleted, directories (and therefore names) will remain.
- * Also, this assumes a fixed-block file system (like FFS, or a V7 or a
- * System V file system).  In a logging file system, you'll have to have
- * kernel support.
- *
- * A note on standards:  U.S. DoD 5220.22-M "National Industrial Security
- * Program Operating Manual" ("NISPOM") is often cited as a reference
- * for clearing and sanitizing magnetic media.  In fact, a matrix of
- * "clearing" and "sanitization" methods for various media was given in
- * Chapter 8 of the original 1995 version of NISPOM.  However, that
- * matrix was *removed from the document* when Chapter 8 was rewritten
- * in Change 2 to the document in 2001.  Recently, the Defense Security
- * Service has made a revised clearing and sanitization matrix available
- * in Microsoft Word format on the DSS web site.  The standardization
- * status of this matrix is unclear.  Furthermore, one must be very
- * careful when referring to this matrix: it is intended for the "clearing"
- * prior to reuse or "sanitization" prior to disposal of *entire media*,
- * not individual files and the only non-physically-destructive method of
- * "sanitization" that is permitted for magnetic disks of any kind is
- * specifically noted to be prohibited for media that have contained
- * Top Secret data.
- *
- * It is impossible to actually conform to the exact procedure given in
- * the matrix if one is overwriting a file, not an entire disk, because
- * the procedure requires examination and comparison of the disk's defect
- * lists.  Any program that claims to securely erase *files* while 
- * conforming to the standard, then, is not correct.  We do as much of
- * what the standard requires as can actually be done when erasing a
- * file, rather than an entire disk; but that does not make us conformant.
- *
- * Furthermore, the presence of track caches, disk and controller write
- * caches, and so forth make it extremely difficult to ensure that data
- * have actually been written to the disk, particularly when one tries
- * to repeatedly overwrite the same sectors in quick succession.  We call
- * fsync(), but controllers with nonvolatile cache, as well as IDE disks
- * that just plain lie about the stable storage of data, will defeat this.
- *
- * Finally, widely respected research suggests that the given procedure
- * is nowhere near sufficient to prevent the recovery of data using special
- * forensic equipment and techniques that are well-known.  This is 
- * presumably one reason that the matrix requires physical media destruction,
- * rather than any technique of the sort attempted here, for secret data.
- *
- * Caveat Emptor.
- *
- * rm_overwrite will return 0 on success.
