'''23 September 2012''': I've updated editliveos.py with bug fixes and simplifications. Run it in from a folder with these files:

https://git.sugarlabs.org/~FGrose/soas/sugar-clone-extensions/trees/master/editliveos

There is also a new Bash script, LiveOS-merge, for merging a LiveOS snapshot and refreshing an installation with the new image. (A new

osmin.img is not created, but it is only used during installation of a traditional image from a LiveOS image.)

'''17 June 2012''': I've posted my working files for a new version of edit-livecd, which I named editliveos.py in this commit,

http://git.sugarlabs.org/soas/sugar-clone-extensions/commit/8c4e03323fc9a7e630e6c62213bb842909fbaa00

It includes editliveos.py, liveimage-mount, and temporary versions of fs.py, live.py, creator.py, util.py (pending incremental patches for livecd-tools acceptance). The livecd-iso-to-disk version is not up-to-date with all the recent changes and improvements.

'''10 February 2011''': A new bundle, named '''[[#SoaS-remix|SoaS-remix]]''', is an installable .iso system image file builder. It includes edit-liveos.py, a launcher named 'liveos-disk-to-iso', and temporary versions of fs.py, live.py, creator.py (pending livecd-tools acceptance).

* With edit-liveos (disk-to-iso), a nearly-consumed overlay can be refreshed by rebuilding the system into a new, SquashFS image that re[[wikipedia:Sparse_file|sparse]]s the system files and repackages them into an iso installation file for reuse or distribution.
