The best way I've found for troubleshooting pre or post scripting errors is to simply put a sleep statement in the pre or post, then manually walk through the script and see where it fails. %pre Sleep 9999999999999 Chip -----Original Message----- From: kickstart-list-bounces@xxxxxxxxxx [mailto:kickstart-list-bounces@xxxxxxxxxx] On Behalf Of Larry Brigman Sent: Tuesday, January 13, 2009 3:11 PM To: kickstart-list@xxxxxxxxxx Subject: kickstart fails to process %pre event I have a kickstart file for doing RHEL5 installs. It works just fine but now as we have moved to having more than one disk in the systems; this automated install breaks as it cannot determine which disk to install the system on. I could write multiple kickstart files to handle 1,6,12,18,24,36 and 48 disk installs but I shouldn't need to. I have added a %pre script, instead, to the file to handle this case but it doesn't seem to even be run. We are doing the installs from pxeboot. I look at the /tmp/ks.cfg file and it has the %pre script embedded but the file that it creates when executed doesn't. The logging page (ctrl+alt+F3) does not show that the script was processed. Additional info 2.6.18-53 RHEL5 kernel anaconda-11.1.2.87-1 How do I troubleshoot this problem?
