I've spent sometime in setting up an autoinst.xml file for use with Autoyast to automate the installation of openSUSE Tumbleweed on my systems.

I was curious whether a manually installed system was different in anyway from an Autoyast based automated installation one and am happy to confirm that there were very few differences under /etc and in terms of packages installed.

I've gone through the list and can account for and understand why there is a difference found for each of the above lines.

One difference I encountered which I wasn't sure the significance about is:

The file: /etc/YaST2/ProductFeatures

This file had the following difference:

Manual installation:
        network_manager = "always"
        default_patterns = "kde x11 base enhanced_base x11_yast yast2_basis"
Automated installation:
* Did not have the "network_manager" or "default_patterns" lines.
What is the significance of the ProductFeatures file? I found some documentation about it here: https://github.com/yast/yast-install...oduct-features but I am unsure on whether this file is used solely by Autoyast or if yast2 relies on it as well. My concern is whether I will face any future issues with the usage of Yast2 because of this difference. Am happy to raise a bug report if the forum is not the best place to ask.
