[suse-security] shred doesn't work in reiserfs?!
-----BEGIN PGP SIGNED MESSAGE-----
I was reading the man page for shred, and it says it is not effective in
reiser. From the man page:
"The following are examples of filesystems on which shred is not effective:
* log-structured or journaled [sic] filesystems, such as those
supplied with AIX and Solaris (and JFS, ReiserFS, XFS, Ext3,

I use shred to delete some important temporary files. I keep some sensitive
info in encrypted files. Once in a while I need to decrypt them, look at it,
and then shred them when I'm done, keeping the encrypted version. It seems
this procedure was giving me a false sense of security, since I use ReiserFS
all around. Can anybody elaborate on this? Is there a shred equivalent for
Reiser, or is Reiser immune to that kind of approach? How easy is it to
retrieve deleted file info from a ReiserFS formatted partition?
Happy new year!
