[rules-users] Guvnor seems to copy assets across External RDBMS and file system

[Tihomir Surdilovic]

Hi Yuri, the lucene search indexes cannot be persisted to the JCR repo. 
They will always be persisted to your local file system. They can be 
removed however between server startups and will get regenerated on next 
use. The Guvnor admin tool generates Jackrabbit configs for different 
databases so its a good thing to use them, but you can always edit the 
generated configurations for your specific needs.
