I assume you mean PID#1 (typically /sbin/init). On Unixes with PID#0,
it's usually the swapper or scheduler task that's internal to the
kernel.

OK. I that I understand. It seems a bit redundant to me: I've been
running Linux since the 0.99 days and never had to pass init= to a
kernel. But, I guess it won't hurt anything...

And the set of init scripts that belong to grub2 are just to try to
auto-magically generate the config file?
