You're absolutely right-- I'll make sure to implement a full suite of
testing in InstallationCheck and VolumeCheck.
It was simply for testing purposes though-- a client wanted to see
what the error looked like. I figured it out though. An exit of
anything greater than 0 seems to do the trick.

How can I get a preflight script to cause the installation to be

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.
