Actually, rsync --delete is not a viable option either. If you first build a kernel with a particular item built as a module, and then afterward rebuild with the same item as built-in (or not at all), the .ko file remains in your kernel build tree (ie, it won't be deleted on the source such that the --delete would have your desired effect). Furthermore, rsync's performance is considerably worse in my testing than "cp -u", almost back to the original performance of the "rm -rf, cp all" of the original modules_install. (Note that I tested, rsync's default, checksum, mod-times, and size-only.) :-Dustin ------------------------------------------------------- This SF.Net email is sponsored by xPML, a groundbreaking scripting language that extends applications into web and mobile media.
