Autoyast file(s)

Hi, I was wondering a few things about the YAST autoinstall config files. I have setup the rules file correctly and all seems to work. Now what i would like to do is to split up the config files so that the <software> section is in a separate file and can be included in different config files. Basically i want custom configurations only for partitioning trees, and the rest to be modular. Another question is, how would i set it up in the config files that when it installs it also runs online updates as well and configures it to do auto-online updates from a specified server? Please let me know Thanks Sascha
