kickstart fails to process %pre event

I'm not getting the "All kickstart %%pre script(s) have been run"
message in the logs.
It is like it is not finding the "%pre" directive in the file.
I even have a simple piece that should never error if it gets run.
echo "pre kickstart script is running" >/tmp/pre-kickstart.out
