How to debug install_packages?

[Thomas Neumann]

How can I get more information on what's going on from install_packages? 
Is there a better way besides set -x and echo?

There's something fishy going on and I don't know what triggers it. 
During a Debian installation i_p tries to call yast and install 
kernel-xenpae. The only time this package is mentioned in my config 
space is in package_config/DEFAULT - but in a way that it should never 
be regarded as "must install this" for Debian (or Ubuntu).
