How-to: Persistence in Ubuntu Live Sessions

No, that doesn't mean keep trying to get Ubiquity to load; it's actually quite good these days, even if the 12.10 testing images are a bit, ahem , broken... Rather, if you boot from a USB drive into Ubuntu as a Live Session (that is, not installed to the hard disk of a machine), you can opt to create a local storage area on that USB drive on which to store session information, additional applications, your profile and some data files. Persistence is just a feature that the live session gives you when enabled during the creation of a bootable USB key using Startup Disk Creator or another tool such as Unetbootin . It creates a file which stores all the settings throughout the live session; files created, system log files and everything that will be normally remembered by a PC from session to session. Otherwise, at the next reboot, your live session everything will be lost.
