Comment # 9 on bug 1031295 from Ludwig Nussel

The request was two fold. Only the second part about uninstallation cannot be
fulfilled. We still need the custom selection to preselect the base and minimal
patterns. So far the control file doesn't seem to preselect any pattern.

Looking at the SLE control file I guess the custom section needs to look like
this:

<system_role>
  <id>custom</id>   
  <default_patterns>base minimal</default_patterns>
</system_role>

There's also no default_patterns node in the KDE, GNOME and Server sections
still it seems to work. Out of curiosity, how does yast know what to install
there? :)
