Comment # 7 on bug 910728 from Stefan Schubert

Hm, I have tried, but unfortunately we have a third case for creating
autoinst.xml;
"yast clone_system" call in an installed system. 
This call produces the same output as the second case.
Sorry, it has been a really nice idea but this solution does not fit
the third case. :-(
We will have to solve it in the package handling area.
Or do you have any additional nice idea ? :-)
