TinyDNS as a secondary DNS

[tmueko]

I'd like to run a secondary DNS on pfSense (actually replace a selfbuild nanoBSD-Firewall using bind).
I read a bit about tinyDNS and think, that the easiest way would be to extract the zones from named.conf and run something like this

for a in `cat zonelist.txt; do tcpclient primary_dns 53 axfr-get $a db.$a db.$a.tmp; done

and then include these files!?
Any idea how to do this with pfSense-package for TinyDNS? Or is there a better way (I'd love to have a standart named…)?
