Based on the new idea for TLD master server policies, I wrote up a new 
script tonight to generate the config file for BIND.  Please see 
http://opennic.oss/files/scripts/srvzone

There are a number of variables at the beginning to define your setup...
- NS0: the IP address of our T0 server
- myDNS: if you want to grab queries from a local server, enter the name 
or IP here
- file_* sets the path where the various zone files will be saved
- destination: where you want the final output to be saved
- tmp_dest: where the initial file is written and validated

Following that are the absolute paths for the commands used within the 
script.  Hopefully I got everything in there.

If you run a T2 server, just call the script and it will generate output 
with all zones slaved.
If you run a T1 server, call the script with the name of your T1 -- 
./srvzone ns1

This script uses a lockfile to ensure only one copy runs at a time. 
Query results are cached during each run to minimize the number of dig 
lookups needed.  The output assumes that only the owner of the TLD and 
NS0 are valid masters for each zone.  This script is completely 
self-contained and runs MUCH faster than the previous scripts I've put 
out to perform this function.

I've tried to make this script bullet-proof, but there will probably be 
issues from running on different platforms.  You will need bash 4 or 
above for the various string conversions that are performed. This script 
will grab NS0 data straight from NS0, but all other queries are local.  
If you run this on a new server with no opennic access (and have BIND 
set up to use the output), it should pull all of the zone files from NS0 
and get you up and running.  The generated output is validated by BIND 
before installing the new file.

You can probably run this script once an hour to stay up to date on TLD 
changes.  Let me know if there's any problems with it.
