[Fedora-livecd-list] Script to merge persistent overlay into new image

[James Heather]

There's an incredibly useful-looking script on here

http://fedoraproject.org/wiki/LiveOS_image

that merges a LiveOS snapshot overlay into a new root filesystem, and 
replaces it on the USB stick, so that you get all your overlay space 
back. I've been looking for such a script for a while.

Is it included in livecd-tools? Or any other Fedora package? (I'm 
reluctant to run the script on the web page, because I'm not sure how 
well tested it is.)

The script appears to claim that it can cope with being run from the USB 
stick itself, while it's booted up, which sounds too good to be true 
(or, at least, too good to be safe).
