It's amazing the way you answer me with this wonderful description of the
problem after only a few tens of minutes while regular Red Hat support is
struggling with my call since many days!
In my opinion, this is a limit to the adoption of Linux in the enterprise
environment: it needs too technical involvement from specialized personnel.
I hope that Red Hat will understand that it needs more expert engineers in
the frontline.

Heartfelt thanks and sorry for my bad english
