Kernel modules allow the system administrator to dynamically add and remove functionality from a running system. This ability also helps software developers to develop new parts of the kernel without constantly rebooting to test their changes. This package provides the necessary utilities for using kernel modules on NetBSD 5.x. The modload utility loads a kernel module specified by the module parameter into the running system. The modunload utility unloads a loadable kernel module from a running system. The modstat utility displays the status of any kernel modules present in the kernel.
