Version 25 of livecd-tools has new tools to help in rebuilding LiveOS images. For example,
* editliveos permits overlay merging and image refreshing,
* editliveos allows overlay and home file system resizing and format changes
* livecd-iso-to-disk allows multi image installation on a single USB disk device
* livecd-iso-to-disk allows sourcing and writing to the same disk device.
Having the livecd-iso-to-disk installer onboard the .iso makes installation of a persistent overlay easier. (Persistent overlays are the standard for SoaS image in a pocket deployment.)
The new tools also work with OverlayFS overlays.
