I now have uploaded efaLive 2.3 to the server. The main difference is that this version is now based on the new stable Debian release “Jessie” 8.0. Besides that there is a small watchdog that restarts the PC in case of a X-server crash. For more details have a look to the efaLive page.
Unfortunately the image size has grown over 700 MB. So you can not burn the image to a standard CD. You need an oversize CD oder a DVD. However, I recommend to use a USB stick, anyway.
