It's rather non-intuitive. It works, but having a static /sbin/init
avoids having to muck around in the loader in order to get to the
rescue bits. If you need the rescue bits, you pretty much always
need to use /rescue/init anyway. A dynamicly linked /sbin/init just
makes it harder to get to the rescue bits, so it makes sense to
link init(8) staticly. Especially since there's no advantage to
dynamic linking init(8) that compensates for the inconvience.
