My opinion, and I've looked carefully (but am no pf
or netbsd rc.d expert), is that the stock netbsd
rc.d defaults are way broken, to complicated with no
benefit. And, they don't seem to work as documented.
If you make install in /usr/pkgsrc/security/pflkm
I think it informs you the proper way to load the
kernel module at boot, there is another config file
to populate -- but I don't recall exactly.

I was going to look for it in source. but lkm.conf(5) seems
to tell you what you need...
The lkm.conf file specifies loadable kernel modules, see
lkm(4), that are to be loaded a boot time. The lkm.conf
file is processed by /etc/rc.lkm at system boot time, if it
Each line of the file is of the form

The patch below just disables the /etc/rc.d/pf_boot
script and the other file is a replacement that does
what you expect.
That's assuming that you expect /etc/pf.conf to hold
your boot time pf configuration and have pf=yes
in rc.conf to load it. If you have pf=yes but no
pf.conf it loads /etc/defaults/pf.boot.conf; also
you can define pf_flags and pf_rules for pfctl opts
and an alternate location for the the conf file.
It doesn't address loading the module or enabling it
in the kernel config, which should probably be part
of whatever procedure puts pf=yes in rc.conf ;-)
I'd planned offer above for base, but I've not
tested it much or worked out exactly what to suggest
to change on base.
