I know nothing about Dtrace, so if something needs to be changed/fixed,
someone who understands these things will have to let me know.

When I built a kernel with "options KDTRACE_HOOKS" and set
dtraceall_load="YES" in /etc/rc.conf,
it booted and
# dtrace -l
- seemed to find the stuff (it's called "dtnfscl", btw).

Someone told me that's how you check it's loaded and that's all I
know how to do w.r.t. dtrace.

If you can test/debug it, that would be great, rick
