Well, the manpage does say: BUGS AND LIMITATIONS The `c', 's', and `u' attributes are not honored by the ext2 and ext3 filesystems as implemented in the current mainline Linux kernels. These attributes may be implemented in future versions ext2 and ext3. If I remember right, it was dropped from the kernel because it was incomplete - inode data isn't wiped, the journal isn't wiped, and if a file is truncated, old data blocks weren't wiped. I think these were decided to be too difficult or too slow to implement, and so the feature was dropped "for the time being." It's been a while since I read the mail thread on this though, and my memory may be faulty. -- Matt Stegman On Thu, 7 Sep 2006, Wolber, Richard C wrote: > > On Sep 07, 2006 07:53 -0700, Wolber, Richard C wrote: > > > I believe you can use the "chattr -s" command to mark all > > > of the files so that when they are deleted, their blocks > > > are wiped with zeros. > > > > In theory yes, but this has never been implemented. > > *BLINK* > > So let me get this straight.
