I am simply of the opinion that you cannot change the leopard's spots. If the fundamental nature of a particular system is (say...) that “it uses a case-insensitive filesystem,” you cannot buck this tide. You can align yourself against it for a time, say with some sort of mountable-file-system nonsense, but you can never change it ... and you can never launch “a successful application” if you try. If your application has any such of a core-requirement... you must change the application. Nothing else will do. “Resistance is futile...”
