I try to set up an automatic update for the Novell Client. Right now my first tests work fine but I need help for some tweaking to make everything work smoothly

1) How to make the client installation run silently ? I have update the acu.ini and create an unattend.txt file.
2) How can I force the ACU to install patches like Login Patch, or any security patch that novell make available ? I put the modified files over the original client file but for ACU it still the same version.

Enough for now. :) Any help will be very appreciated.
