Thank you very much for your attention - however I asked where I can find exact documentation about these things?

"Mr Brown from Suse wrote in a HN thread..." will not be enough as a reliable source of information. Yes, I could just read the source, however I am expecting such an extraordinary important thing that will change my config files to be documented. I need precise information here.

Also it would be important to know how this conflicts with configuration management systems like chef, ansible, puppet etc. - or is yast able to manage multiple workstations itself, so is is a replacement for these tools?

Thanks!
