Well, I think secure deletion should be an option for everyone. Using
encryption is a data hiding technique, you prevent people for detemining
what sort of data is being stored there. Now, admittedly I dont know at
what level the reiser4 encryption appears, but I would think its safer
to have complete erasure when a file deleted regardless of how well
protected its contents were.

just a thought.
