Comment # 6 on bug 1187425 from Adrian Schr���ter

I added the 

  default_obs_repository_name

element inside of 'installconfig' element.

Please note that this obs stands for the definition of the use OBS instance,
while zypper has hardcoded obs to build.opensuse.org afaik.

This requires new product converter 1.4.6 and update in obs code:

back to zypp people ....
