Would it not be better to do these special settings for init from
init itself?

So if you mean from within the kernel context that is doable,
so long as we only have one process with pid == 1.
Although we may be able fix the kernel limitations in setsid().
For multiple pid == 1 case I don't know of another place in
the kernel I can possibly put this. I can't put it later
because there is no place later, and I can't put it earlier
or else my efforts would just get stomped.
So I did it this way so I don't have to come back and change it to
this next week. I'd love to have a better place to put this
code.
Eric
