A very simple convenience factor. If the firewall is cracked in some form,
a simple reboot will re-initialize it, forcing the attacker to re-crack
it, if he or she wishes to retain control of it. If the attacker was a
rather casual peruser, he or she may not bother re-cracking, and your
life can go on as normal for a few days while you build a new firewall
that is not vulnerable to whatever was used in the attack.
Of course, this assumes the attacker was noisy enough for you to notice
it. If he or she does his or her job well enough, you'll never notice,
and you're right -- there is practically zero benefit to having the
rules be on a CD-R at that point. :)
