Little help with postinstall script in packagemaker

[XLR]

Posting it here because i'm not sure what's the right forum for this question...

 

I'm trying to make a simple kext installer via packagemaker, but having troubles with postinstall script in order to make it work in ML:

 

#!/bin/sh
cd /System/Library/Extensions
sudo chown -R root:wheel AppleHDA.kext
sudo chmod -R 755 AppleHDA.kext
sudo rm /System/Library/Caches/com.apple.kext.caches/Startup/kernelcache
sudo diskutil repairpermissions /System/Library/Extensions
exit 0

 

Can you please tell me what am I doing wrong? I'm afraid all this script is full of wrong...

 

Thanks in advance

#!/bin/sh

sudo chown -R root:wheel /System/Library/Extensions/AppleHDA.kext

sudo chmod -R 755 /System/Library/Extensions/AppleHDA.kext

sudo touch /System/Library/Extensions

sudo diskutil repairPermissions /

exit
