I thought I answered these about two weeks ago on the eCS mailing list. However, I'll answer again.
Sorry, but this informations unfortunately never reached me. Thanks though.
And once again - my Intention is not to blame someone or something, it is just that I want to point the developers to - in my opinion - some theoretical but important problems users might have or face while trying to install ecs 2.2.
Theoretical because unfortunately it is not possible to test a beta as it is reschedulded and therefore delayed from month to month.....
