No, modifications done on ou=schema are persisted on disk. Only the 
modifications done on cn=schema are not persisted, AFAICT.

I'll create a JIRA and a test to demonstrate the issue.

Fixing it should not be a problem, it's just a a matter of converting 
the schema element (which is passed using the schema element syntax) to 
a meta-schema entry, and propagate it to the backend.

Remember that modifications to cn=schema are *not* allowed (it's a read 
only data structure) from outside the server, but it's always possible 
to modify the rootDSE subschemaSubentry attribute, as it contains all 
the loaded schema element. This will, in fact, impact the cn=schema, as 
it's just a LDAP exposition of the loaded schema.
