I want to make sure a few things happen in the preflight script and I would rather have the installation error out then to continue with installation. It is considered Bad and Wrong to error during preflight, especially if your installer might be part of a bigger metapackage. I am not sure what Installer does when you return an error. I have always made sure not to. I realize this is not so helpful, but gosh, would you like to come back from lunch and see that your install stopped 2 minutes into its 45 minute run? There must be some kind of way to check for errors during InstallationCheck or VolumeCheck instead. This email sent to site_archiver@lists.apple.com
