Disable auto reboot after initial installation?

Hi there, I'm wondering how to disable auto reboot after the initial phase of installation is completed. In chapter 4 of the docs it states: "Change starting from SUSE Linux 9.1/SLES9 The reboot property in the mode resource was used to force a reboot after initial system setup and before the system is rebooted for the first time. Currently after initial installation all systems must reboot, which makes this option obsolete." So are there any methods to turn off the auto reboot? I tried to enable the "interactive_boot" as well as "confirm" options in the yast xml config file but seems it can't prevent automatic rebooting. Any hints? Thanks in advance! Best Regards,
