Re: major security bug in reiserfs (may affect SuSE Linux)

Some more playing around showed that the 'hidding' depends on the actual
filename. Lots of x in my 1st example did the magic other chars won't.
I'd guess its depended on the sequence in the dir(-listing). Similar to
the observations of Andreas Ferber.

People with insight on the actual btree should have some clues.

The scary thing is that people can screw up systems just by
writing to {/var,}/tmp/<log random name>
One won't recover that diskspace.

Bash won't interpolate the asterisk. That way echo * prints *.
Csh prints echo: No match.
I had no success using strings on the directory itself.
