After thinking about it, I think this patch from Matt Kraai is probably the
best way to go. Sysvinit does not provide a controlling tty since it doesn't
even try to open ttys for apps. We do. So we should _try_ to provide a
controlling tty if possible, but we needn't freak out if it doesn't work. This
way we won't need to use openvt or similar, we'll just have init do the Right
Thing(tm).
