Seeing setup assistant unexpectedly

I created a payload-free package with the following script as a postflight: [code]#!/bin/bash touch /private/var/db/.AppleSetupDone chown root:wheel /private/var/db/.AppleSetupDone chmod 600 /private/var/db/.AppleSetupDone touch /Library/Receipts/.SetupRegComplete chown root:admin /Library/Receipts/.SetupRegComplete chmod 400 /Library/Receipts/.SetupRegComplete exit 0[/code] After applying the image to a machine, I get the setup assistant. What have I done wrong? Thanks in advance!
