I have the following problem. I am trying to make Ubuntu Live USB (actually Lubuntu, but problem is the same with Ubuntu) with the persistency option. I use Unetbootin (both on Windows and Ubuntu problem is the same), set all options - and have working USB stick with Live CD. The problem is, even if I set preserved space to 1 Gb, I can't save any changes made on USB.

My test is the following - I make USB stick with Live CD, I Try Ubuntu without installing, type command:
sudo adduser cheshire
fill all details, I have two folders in /home/ catalogue - ubuntu and cheshire. But after reboot I have again only /ubuntu/ catalogue. Actually I really need USB stick which will preserve this data - what I need the most is the openssh-server option.
