I'm new to rpm internals.  When you say it reads the data records, which data records do you mean?  Records from the berkley database named "Packages?"  Records from several of the databases in the rpm database directory?  Something else entirely?  

I feel like I'm misunderstanding something here, because if a rebuild must be able to read records from the current database, it wouldn't do much good if the current database is unreadable, however, I have found that rpm --rebuilddb does work when the current database is unreadable, at least in one limited situation.  (db5-based version of rpm trying to use files from a db4-based version of rpm.)  

What do you mean be ignoring indexes?  (These don't sound like indexes in the SQL sense.) 

Thanks!
