I know that article and I've tried everything in it, except the "Optify Python" part. Have you tried that? And what else have you tried?

One thing in particular is that that article used to mention the ccooke's script ( http://talk.maemo.org/showthread.php?t=33429 ) and no longer does so. I'd really like to ask questions about that solution, though.

Also, how often have you tried the solutions in the wiki article? Can it really clean the rootfs more than one time? I've tried those script solutions currently in there, and they all failed.
