Yeah, I suppose you could store this in LDAP. Seems like overkill 
though. All you really need is a list. Personally, I use DNS itself for 
this "metadata" -- a special zone with a PTR record (PTRs aren't limited 
to "reverse" zones, you know, and are more compressible than TXT 
records) for each zone which needs to be slaved. The general slaves are 
also slaves for this special zone, and on a timed schedule, they check 
whether anything has changed and reconfigure themselves from templates 
automatically. One of the beauties of using DNS itself for this metadata 
is that it doesn't require opening up any extra firewall ports (I'm 
using this in a Border Gateway Network scenario so that's an important 
consideration for me).
