Also, after reading a previous post on this list, I would keep updates to only things you care about since the overlay file records block changes and you will eventually run out of overlay.
This is the case and unfortunately, with things currently in the

I don't really see any way around it. Modulo writing some tool to (likely offline) analyze and rewrite the snapshot file. But relatively deep dark voodoo required to write such a tool
I don't know if this would be easier, but what about a tool that would incorporate the changes back into the image file and then re-zero the overlay?
The problem is that incorporating the changes back in basically boils down to "make a new image". Which isn't that difficult to do, it's just a matter of having the disk space for it and also the time -- it'd largely just be a matter of running good chunks of the livecd image creation process over again.

Well, I don't know about other users of the live USB system, but that would
be okay with me. A prereq. would be you have enough HD space to copy the image, update it, and then copy it back to the USB drive.
