I've built about a dozen software distribution packages that all silently install quite nicely. When I build a provisioning template and add each of these distribution packages using the "Distribute Software" task, some of them will display windows and other bits of UI on the client-end during installation, despite originally being silent. One of them even had a prompt for reboot that I was forced to decline on the client machine before it would continue to the next task. I've tried unchecking "Show client UI" in the provisioning template's "options" area, but this just disables the UI for the provisioning task itself, not the UI that comes up from the individual distribution packages.
What gives? Is there some way to make all of this silent once again?
