I've seen multiple threads on how to expand a Live persistent Ubuntu USB to use more than 4 GB.
What I can't quite determine, is if there's a way to expand the current running Ubuntu USB to full disk.
In other words, I am currently running Ubuntu on a 32GB USB stick. Can I expand that, while using it? Or do I have to take some steps and use a second USB stick to expand my current version. (I also assume expanding my current USB to full disk will overwrite any data currently on it and I'll start from scratch?)
