Hello all,

I have created a bootable flash drive with 9.10 (Karmic) and enabled persistance mode in order to create settings and alter the installed programs. The trick is: I've gotten to the point that I have worked out the web problems (ie. flash, java, codecs, etc.) and assembled a good collection of software so that a person using the LiveUSB as a demo of Ubuntu can actually have a fully functional experience instead of the bare-bones LiveCD; however, I do not want further changes taking place.

I am trying to find a means of undoing persistence so that any further changes are discarded at startup, but everything that has been installed & changed up to this point will remain. Preferably, I would like a way to go back and update/install more, but I understand this may be a one-time deal.

Any ideas?
