This is quite a hack. Without it the installer warns that a newer version is installed on the target drive and later refuses to install saying 'You cannot continue. There is nothing to install.' Am I am missing something here? I've seen something similar with a package being installed through the installer command line tool. The installation fails silently even when the IFPkgFlagAllowBackRev flag is set. This email sent to site_archiver@lists.apple.com
