specify install-server in the xml-file?

Hi, Im a novice with autoyast, but have used kickstart for several years. I have install-server (http) for installing NLD9 clients. I boot the machine with CD1 of NLD9 and enter "autoyast=http://server/profiles/profile1.xml install=http://server/image/NLD9/i386" and everything works. But, I want to embed the "install=" in the xml, is that possible? ( kickstart has url of image in the kickstart-profile ) I have tried with linuxrc but it doesnt work. Any pointers? Regards Daniel
