: The ''livecd-iso-to-disk'' installation method has other advantages over the ''liveusb-creator'' method by allowing the creation of a separate,  persistent /home/liveuser folder with the <tt>--home-size-mb ''NNN''</tt> option. This feature avoids consumption of the write-once persistent overlay for Activity storage (see [[LiveOS image]]) and allows one 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).
