[PLUG] secure file deletion with journaling filesystems

["Gregson Helledy" <gregsonh@gra-inc.com>]

I like to have a way to securely delete files on computers I use.  On my
Windows 98 machine at work,
 I have Eraser (http://www.iki.fi/st/eraser).  Linux (well, SuSE and
Libranet) come with shred.
However, a quick look at shred's man page warns that it's not useful on
journaling filesystems.  This
would include reiser, ext3, xfs, I guess all of them except ext2.
I'm pretty ignorant about filesystems; is it logically impossible to have
secure deletion with a
journaling filesystem, or is shred just not the tool for the job?

While we're on the topic:  is NTFS a journaling filesystem?
