I would feel better, when the box is either completely unreachable (due to disabled hardware (e. g. down'ed interface)) or at least protected by a packet filter _all_ the time... That is one reason why I use ipfw _and_ pf at the same time on all my boxes... As you can see in appendix A ipfw2 is initialized even before the hard disks but after the network interfaces, which are detected some lines early. Are the NICs still down and _safe_ after that detection phase? Isn't it possible to just activate pf just like ipfw in order to deny all incoming and outgoing traffic (to me it looks like a design flaw, when the boot up scripts rely on a misconfigured/disabled packet filter...)?
