--- Comment #3 from WHR <msl0000023508@gmail.com> ---
(In reply to Conrad Meyer from comment #2)

I knwon that ptrace(2) can't be used to debug any kernel processes, allowing
that would hang or panic the kernel; but process 1 (init(8)) isn't a kernel,
but an user process, right?

> Have you tried using gdb on it with this patch?
Yes, I has been used a 10.3-RELEASE-p29 kernel with this patch applied, for=
 a
long time; I can debug init(8) in gdb(1) any time, without any problem.
