wipe utility

[gaf at blu.org (Jerry Feldman)]

I might have mentioned this before, but when I was an HP consultant at
Raytheon in 1999, we had a system that was in the classified lab that
Raytheon wanted to move out of the lap. One of our consultants wrote a
wipe utility that was approved by security. 

Wiping an entire drive is more effective than wiping a file, at least
under Unix and Linux. Information contained in a file can appear in
other places, such as the swap area. I don't think that there should be
too much of an issue on the journals since they contain meta data, not
the actual data.
