Actually, you could whip up a quick expect script to even automate this part
if you really wanted to (although the security of that is obviously
non-existant).

Good point.  The author points that out... I just hadn't read far enough
when I hit the send button.

This has me thinking: shouldn't it be possible to do a byte-by-byte
overwrite of the file in place?  Or am I misunderstanding the way that the
journal works... Will the journal reallocate blocks that are currently
allocated to a file?

Just thinking out loud, and showing my ignorance on the way JFSes work...
