where to store the config?

Hi, I have a problem, I have to make an autoyast install (SuSE 10.0) for clients that do not have floppy, cd and network. I only have an external USB-DVD and an USB-stick. I tried to store the autoyast.xml on the USB-stick but Yast can not access it. I am confused because of the situation: /dev/sda -> SATA harddisk /dev/sdb -> USB-Stick I give the bootoption: autoyast=/dev/sdb1/autoyast.xml Yast shows the error: Can't find /dev/sdb1/autoyast.xml when I change into tty I am able to mount /dev/sdb1 and can access the autoyast.xml what's going wrong? Is it possible to "remaster" the install-dvd and store the autoyast.xml there? bye fisch
