installer.app 'main script execution failure' & moving your Applications

Firmware 1.1.4

If you have moved your Applications to your mobile directory (/private/var/mobile/) you might have problems with your installer.app permissions.

Howto move your applications from your small root partition :

  • cp -r /Applications /private/var/mobile
  • mv /Applications /Applications.old
  • ln -s /private/var/mobile/Applications /Applications

CD into your now-moved Applications folder and do the following :

  • chmod +s Installer.app/Installer
  • chown -R root:wheel Installer.app

This worked for me. YMMV, of course.
