Currently, we parse the first line of '*.mod' files in $(MODVERDIR). Since we have duplicated functionality here, I plan to remove MODVERDIR entirely. In fact, modules.order is generated also for external modules in a broken format. It adds the 'kernel/' prefix to the absolute path of the module, like this: kernel//path/to/your/external/module/foo.ko This is fine for now since modules.order is not used for external modules. However, I want to sanitize the format everywhere towards the goal of removing MODVERDIR. We cannot change the format of installed module.{order,builtin}. So, 'make modules_install' will add the 'kernel/' prefix while copying them to $(MODLIB)/.
