Yes. It is a bug, and the description reparent_to_init is likewise

I have recently realized that a number of the inital pid namespace
patches have stupid little bugs in them like this. I am upset with
myself for failing to code review them closely before the went in.
Live and learn I guess.

So when I saw this I added this to my growing list of things I needed
to review before I could assume they were done correctly.

Feel free to fix it. I'm still a couple days out from having enough
time before I can start working on pid related issues.
