In the output below, notice there are two modules named "ng_sync_sr"
loaded in the "kernel" object (due to a typo), and moreover there's
a "netgraph" module loaded in both the "kernel" object and the "netgraph.ko"
object..
$ kldstat -v

20 ng_socket
3 2 0xf07f5000 4000 netgraph.ko
Contains modules:
Id Name
19 netgraph
Why and how does the linker allow this? It seems like:
- When the kernel was compiled, the ng_sync_sr conflict should
have caused a failure
- When the netgraph.ko was kldloaded, there should have been
an error from the conflicting module names
Curiously,
