This would of course depend on when the receipt is modified. Yes, I can detect when the version I'm about to install is identical, but what can I do in the preupgrade script to prevent it from actually overwriting those files? Is there a flag or setting I'm not seeing? I *could* use an InstallCheck script, but I only want to prevent one component from being overwritten, and not the whole install.
