script to rebuild zone file

A client of mine has been having problems with customers creating subdomains in cpanel, and then later removing them by just deleting their root directory, leading to dead dns records.

I'm working to produce a script that parses /var/cpanel/users and outputs a zone file for only the records that have matching vhosts in httpd.conf AND have an existing server root.

Does anyone have any suggestions/ideas? I'll post the script in this thread when it is finished in case it is useful to somebody.

Thanks!

 

turns out, i found this (http://www.ndchost.com/solutions/licensing/cp/extras/rebuildnamedzones) script which does just what i need.
