I have been running Clonezilla Live Experimental 1.2 on my Ubuntu Linux machine with very good results.
My only concern is that during the "Assembling MD Arrays" text phase of startup there is an alarming error message (in red) saying "Failure! ...), as no arrays were found.
Maybe a more neutral message simply stating that no MD Arrays (whatever they are) were found, without calling it an error would be less alarming to non-experts such as myself.
Separately, in the list of screen resolutions at the front of the program the resolutioins do not seem to be in logical order.
