> shred's man and info pages devote several paragraphs to explain "a
> very important assumption: that the file system overwrites data in
> place."

> However, they don't mention that the underlying storage also has to

> I think shred's documentation should devote a section to storage media, too.

> (On a side note, the man and info pages are slightly out of sync. E.g.
> the info page mentions BFS and NTFS as journaling file systems, the
> man page doesn't.)

I installed the attached patch to fix the problems that you mentioned, except that I didn't add a section on storage media, data remanence, and data forensics (partly because a lot of this stuff is secret).

If someone would like to contribute text in that area, it would be a good thing to have (if only to discourage even more users from using 'shred' :-). In the meantime I'll take the liberty of closing the bug report.
