I was inspired by the PFIL_HOOKS discussion to check my firewall rules :)
There were none, other than 65535.  Apparently, /etc/rc.d/ipfw attempts
to kldload ipfw, which will fail if ipfw is compiled into the kernel,
and since the precmd failed, the _cmd will not be run.  When did it
become mandatory to have ipfw as a module, not compiled in?  Is there
some rationale for this?  It strikes me as rather dangerous, especially
for firewalls, especially when default-to-accept is chosen.  Am I just
confused, and missing some obvious bit of config?

Is it relevant that my /usr is on vinum, and the rules are in /usr/local/etc?

Thanks,
Barney
