[Greylist-users] what do you do to preserve pf tables over reboot? (spamd)

On rebooting a system running OpenBSD spamd, the contents of
<spamd> and <spamd-white> will be lost.

The obvious thing that springs to mind is to do something like

pfctl -T show -t spamd > <somewhere>/spamd.txt

from cron every five minutes, then reload it with

pfctl -T add -t spamd < <somewhere>/spamd.txt

on system boot up.

Seems rather clunky; is there a neater way?

I thought at first this was what the "persist" keyword in pf.conf was for,
but it's not.  Giving a filename and persist does not write the updated
table back to the filename, though that would be a nice feature :-)

What do you all do?  Do you just lose the greylisting tables on reboot
and live with the delay as you slowly rebuild them?
