Nope, as currently we are already keeping a backup (.dpkg-tmp) file until the extraction of the whole package has finished. So we switch from file + file.dpkg-tmp to file.dpkg-new + file.dpkg-tmp (which is just a hardlinkg of file) + file, for every file in the extracted package. regards, guillem -- To UNSUBSCRIBE, email to [email protected] with a subject of "unsubscribe".
