* '''Latest news''': An alpha version of a python script that allows one to rebuild a custom iso image from a running image by 1.) staging the build on an attached hard drive and then 2.) copy only the content already on the current image.

The ''livecd-iso-to-disk'' script should be used to install the new build, but it currently doesn't propagate a home.img file from the iso, so you will have to manually move the home.img file to the /LiveOS/ folder of a new USB device.
: With a GNU/Linux system, the iso image file can be auto-mounted in Nautilus and one can see the file to copy in the /LiveOS/ folder under the iso-image device.
If one only wants to refresh the source Live USB stick <u>that was installed with a {{Code|home.img}}</u>, then the home folder does not need to be transferred. The following commands will will refresh the overlay and system image:
* Boot into another image (such as from another SoaS device) with the target SoaS device inserted into a second USB connection port.
* From a root user Terminal activity or console session, issue this installation command:
*: /path/to/livecd-iso-to-disk --overlay-size-mb NNN --unencrypted-home /path/to/refreshed/image.iso /dev/sd?1
* One needs to determine the proper paths on the working systems (for example, on a booted Mango Lassi, the path is {{Code|/LiveOS/livecd-iso-to-disk}}.
If the source Live USB was installed without a separate {{Code|home.img}}, then the above commands will also refresh your image, but it will consume the overlay more rapidly as all Activity storage is in the write-once overlay storage.
(Some of the above statements need to actually be tested. So please do so.)
