There's a whole host of issues around schema with cn=config that's not 
really addressed right now.  What if a core schema element changes due to 
some RFC, and that's updated in a future OpenLDAP release.  How do the 
cn=config based LDAP servers update that schema? etc.

What I do, after raising this issue with other of the OpenLDAP developers, 
is copy in the schema files shipped with the release (after stopping 
slapd).  I do this for Zimbra's private schema (which changes regularly) as 
well.

As you wondered, this could be problematic if there are schema changes that 
are not compatible with your existing entries.
