This is more-or-less the approach I use, too. I have a script that
runs a bunch of iptables commands, setting up the rules the way I want
them. Advantage of that over iptables-save is that I can annotate the
script with comments (eg if an IP block is banned, I can say what the
block represents, why it's banned, and importantly, *when* it was
banned, so I know to review it). Also may be convenient is scripting
ip{,6}tables to use a lot of the same rules; again, it's easy enough
when you have your source code as a bash/Python/Pike/etc script rather
than just a series of commands. Plays nicely with source control, too.
