Right.  For a container, <init> would be the only member of <os> as well
right?  At the moment, I don't know of anything else that we will be
adding to <container>.

I guess my only hangup there is the case where the value of <init>
specifies something that is not an init like application.  In that case,
at least to me, it seems less suited there.  Of course, I don't know how
likely or feasible such a use would be.  I can definitely agree with your
comments from a consumers perspective.  I don't have a big problem with
moving <init> to the <os> block.
