You sure are an amusing guy. Rude, but amusing :-)

see their opinion about the topic.

dof needs to inject the probes in /dev/dtrace/helper, so the user needs =
rw access to the /dev/dtrace/helper. I specifically added write access =
to the wheel group for this.

Invalid argument

This error usually means that there were no probes found in dof section =
of the binary. Somehow they were not inserted correctly during the build =
stage.

Yes.
