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

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?
Below is my kickstart file
