OpenBSD Loadable Kernel Modules

LKMs in OpenBSD aren't intended to cut the size of the kernel down, as with Linux.

From LKM(4):

Loadable 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.

I get the idea that they're used much more in the second capacity than in the first; the default kernel (which users are strongly advised not to stray from) doesn't even enable Loadable Kernel Modules.
