macOS PackageMaker - postinstall script is not running

[greg.schumacher]

Using PackageMaker v3.0.1 with Mac OS X v10.5.8, I am trying to create an installer package that copies two file to a new folder and then runs a shell script. The folder is created, the files copied, but the postinstall script does not run. How do I know you ask. I replaced the contents of the postinstall script with the lines below and the text file was not created. Looking in the installer's log I find nothing to indicate an error or even an attempt to execute the postinstall script.

#!/bin/bash
echo "we were here" >> /test.txt
exit 0

The script's execute bit is set and I believe the permissions are set correctly. If I browse through the contents of the .mpkg package I find, buried deep within, the postinstall script. BTW, if I CD to the folder in which I find the script and type ./postinstall the text file is created successfully.

I have run out of things to try and appreciate any assistance you can provide. I've attached to this post the installer's log file for those interested.

[chown33]

echo "we were here" >> /test.txt

Without permission to write to the root dir, that command will silently fail without creating a file.

Try something that doesn't require file-system permissions, like:

say "Go away before I taunt you some more."

The script's execute bit is set and I believe the permissions are set correctly.

Exactly what are the permissions?
