How can the creation of an intermediate (temporary) directory, a chown operation on the directory, installation of the file(s) to the intermediate directory, finally installing the file(s) from the intermediate directory to their ultimate destination, and deleting the temporary directory improve the performance of install? I believe Nate (and I) is trying to avoid the (unnecessary) installation procedure if the target file already exists and the source and target are the same. -- Steven G.
