Here is the live DVD with working live-installer:
yast2-live-installer package is NOT broken, yast stuff around it was broken, here are the bugs to track, with trivial fixes to those workaround:
bugs 890800, 876555 and 890834
The DVD is created using Factory and YaST:Head repos of yesterday(7 Aug).
If someone finds any issue with live installer please file bug report on bugzilla, I am sure YaST team is quite capable in dealing with it and there is plenty of time to fix those before 13.2 is out.
Would it be possible to put it through openqa to see everything works?
