I wrote and tested that script.

I frequently use this Python script, editliveos.py, which can be run from a
directory containing these files:
https://git.sugarlabs.org/~FGrose/soas/sugar-clone-extensions/trees/master/editliveos

The output of editliveos.py --help is here:
https://git.sugarlabs.org/~FGrose/soas/sugar-clone-extensions/blobs/master/editliveos/editliveos-help

If you run editliveos.py from a booted LiveOS image, it schedules a reboot
1 minute after completion.  Errors sometimes appear after the filesystems
are swapped, but the new rootfs.img or ext3fs.img has always been good.  If
you use a separate home.img filesystem, it can have some unclosed inodes
that are cleaned by e2fsck.
