I thought that as well, except that init is one of the kernel-defined
boot parameters that it accepts (man bootparam, for more info), so the
kernel can easily change what's called.
After a bit more research using different terms in google, I stumbled
upon this page:
I'm not exactly sure how the kernel determines what to pass to
/sbin/init (or perhaps what init ignores), but it does some how
distinguish what's a kernel module parameter, and what's not.
Regardless, /sbin/init does seem to be the culprit.
