Hi Kylene, This works as long as the .config hasn't been changed so that some configuration options haven't been changed so that a driver which had been previously built as a module is now built into the kernel. In that case, you really want to make sure the no-longer applicable .ko file has been removed from the system. If the developer knows that to be true, they can use your proposed modules_update without any problems. As a suggestion, something that might be worth trying would be to change to modules_install so that it uses cp -u, but also so that it tries to delete all files that could have previously installed as modules (by using the obj-y list). This should hopefully speed up modules_install, and make it do the right thing all the time.
