This quote from man shred may be relevant to this topic: "CAUTION: Note that shred relies on a very important assumption: that the file system overwrites data in place. This is the traditional way to do things, but many modern file system designs do not satisfy this assumption. [...] " In the case of ext3 file systems, the above disclaimer applies (and shred is thus of limited effectiveness) only in data=journal mode, which journals file data in addition to just metadata. In both the data=ordered (default) and data=writeback modes, shred works as usual." So apparently one can delete files (at least with shred) from ant ext3 filesystem as long as the data itself is not journalled.
