Yes, the firehol config is just a bash script, so you can call external
A note of caution though: ideally your firewall will come up before your
network interfaces, so that you are protected from the outset. This

Do you need it to re-resolve at boot time? i.e. is loading the last set
before reboot not sufficient, or will the host be down for extended periods?
