:: Normally, the ''livecd-iso-to-disk'' installation has the advantage over the ''liveusb-creator'' installation method by allowing a persistent /home/liveuser folder with the <tt>--home-size-mb ''NNN''</tt> option. This feature would allow you to update the OS image while keeping the user files (by running the script against your existing installation but <u>leaving out</u> the --home-size-mb NNN option).
