[Sugar-devel] LiveCD with image writing activity (was Re: easier installation of soas)

[Frederick Grose]

When it comes time to build the LiveUSB images, one should consider
the options, below, from the livecd-iso-to-disk.sh script.

Unless a home.img file is created (by specifying a --home-size-mb
NNN), the user may be surprised, disappointed, or frustrated with the
difficulty in keeping saved Activities should they decide to update
the Sugar version on their USB drive.
