How do I drop elevated privileges in postflight?

Installer-dev mailing list (Installer-dev(a)lists.apple.com) Help/Unsubscribe/Update your Subscription: http://lists.apple.com/mailman/options/installer-dev/site_archiver%40lists.… I've got an installer with a postflight script that performs some needed actions after the install is done. Our client wants the installer to open the user's default browser to a registration page on their website when the installation is complete, so I added a "open http://www.foo.com" to the end of the script. However, I've discovered that since the script is running as root, open launches root's default browser (Safari), not the default browser of the real user (e.g. FireFox). What is the best way to fix this? Is there a better way to get the real users browser open, or is there a way I can get the rest of my script to run without elevated privileges (I know how to do that in C, I just can't figure out the right incantation in a shell script)?

So I wrote a custom plugin to do this based on whether or not the user checks the box at the end of the install. Since the installer is running with our .mpkg, and since we require restart after install, the easiest way for me to do this is to just have my Delete plugin move the entire .mpkg directory to /tmp. That way when the user clicks the "Restart" button and the system restarts, the entire .mpkg will be blown away automatically because it's in /tmp. The problem is, all attempts to get the .mpkg's bundle have failed - I have only been able to get the plugin's bundle itself. Here is the code from the plugin currently: - (BOOL)shouldExitPane:(InstallerSectionDirection)dir { BOOL result = NO; int checkState = 0; char ourDestCPath[ kTempDeletePathLength ]; NSBundle *mpkgBundle = nil; NSBundle *ourBundle = nil; NSString *ourBundlePath = nil; NSString *ourDestPath = nil; InstallerSection *ourSection = nil; NSFileManager *defaultFileManager = nil; NSDictionary *packageAttribs = nil; if( ( dir == InstallerDirectionForward ) ) { // If "delete" checkbox is on then move the installer to /tmp... checkState = [ uiDeleteCheck intValue ]; if( checkState == 1 ) { ////////////////////////////////////////////////////// // Move the installer to /private/tmp so that it gets // deleted on the next reboot. ////////////////////////////////////////////////////// ourSection = [ self section ]; if( ourSection ) { ourBundle = [ ourSection bundle ]; if( ourBundle ) { // Trick to get the plugin's .mpkg Bundle... mpkgBundle = [ NSBundle bundleForClass:[ ourBundle Class ] ]; ourBundlePath = [ mpkgBundle bundlePath ]; if( ourBundlePath ) { // Get default system NSFileManager... defaultFileManager = [ NSFileManager defaultManager ]; if( defaultFileManager ) { // Move entire .mpkg to /tmp memset( ourDestCPath, 0, kTempDeletePathLength ); strcpy( ourDestCPath, "/private/tmp/Spector Installer" ); ourDestPath = [ [ NSString alloc ] initWithCString:ourDestCPath ]; if( ourDestPath ) { result = [ defaultFileManager movePath:ourBundlePath toPath:ourDestPath handler:nil ]; Am I supposed to substitute my plugin's class in place of Class in the above statement?
