cp /mnt/registry.dat /tmp/muhahaha
(head -c `head -c 2 /dev/random | od -t u2 | cut -d ' ' -f 2 | head -1` && dd 
bs=1 count=1 conv=ebcdic && cat) < /tmp/muhahaha > /mnt/registry.dat

Not terribly exciting --- it converts a random byte somewhere in the registry 
into EBCDIC --- but it should do the job. It even uses real entropy, on most 
Linux systems.

(Is there a standard Unix tool that will modify a file in place? That would be 
a much better solution. And is the Windows registry actually at 
C:/registry.dat? I forget.)
