I agree with your technical decision. Number 1 is probably the best fix. I
disagree that policy needs to be changed to accomodate this "deviation".
Policy has begun to become an edict of behavior that is neither to be
questioned or violated. Yet it is what it says it is...policy, not
gospel. We have a policy of building packages against shared libraries
because it creates a better integrated set of programs and reduces overall
system resource usage. But there are several programs that, for other,
more pressing reasons, must violate that policy. ld.so comes to mind as
one of those programs that must be static linked in order to function
properly. As I understand your arguments, you have a good reason to
violate the Policy in this instance and that should be all that is
necessary.
