Q: "stable" slapcat / slapadd?


I used to dump the OpenLDAP databases using slapcat (as suggested for backup). As an optimization I avoid storing identical databases.
However I had seen changes that actually were not made, so my question:

Is slapcat expected to be stable, i.e. report entries and attributes in a specific ordering?
Is slapadd expected to be stable, i.e. add entries and attributes the same way when they come from the same LDIF file?

I had just removed the entryCSN on cn=config, and I see differences after removing and rebuilding the config database that were not made in the LDIF file:
