I've written a kernel extension that behaves well when I load and

PackageMaker project to make an installer. "Kernel Extension
Concepts" was very helpful with this. Running this installer does
put the kext in System/Library/Extensions, but when I reboot the
kext is not loaded.
I have looked into Network Kernel Extensions Programming Guide (my
bible through most of this project), System Startup Programming
Topics, Software Distribution and Kernel Extension Concepts. Nowhere
do I find a clear statement of how kexts are loaded at boot time.
Hello David,
The simplistic answer to your question is provided under the Network
Kernel Extensions Overview of the NKE Program Guide.
"Loading a kernel extension is handled by the kextload(8) command
line utility, which adds the NKE to the running Mac OS X kernel as
part of the kernel's address space. Eventually, the system will
provide automatic mechanisms for loading extensions. Currently,
automatic loading is possible only for I/O Kit KEXTs and other KEXTs
that they depend on."
The last sentence says it all. It sounds like you want to create a
StartupItem to load the NKE. If so, then take a look at the following
doc.
