I investigated some more.  I looked at /etc/rc and discovered that
/var/run/rc.log contains a log of the rc.d system start-up.  I checked
it, and it contains:

===
[running /etc/rc.d/npf]
Enabling NPF.
===

So, it looks like it's starting NPF OK.  To further check this, I added
the following to the end of /etc/rc.local:

===
/sbin/npfctl show > /tmp/rc.local-npfctl-show.txt 2>&1
===

And after booting, that file in /tmp contains what I would expect as
if everything was OK at that point in the boot (which I understand is
fairly late in the start-up):

===
# head -n 2 /tmp/rc.local-npfctl-show.txt
Filtering:      active
Configuration:  loaded
===

But again, when I log into the machine via SSH after it boots and run
"npfctl show", somehow NPF is off and the configuration is empty:

===
# npfctl show
Filtering:      inactive
Configuration:  empty
===

So, NPF is ending up turned off with an empty configuration between when
/etc/rc.local ran and when the rc.d system start-up finished.

Any ideas on what is causing this?

Thanks!
