Please file a bugzilla report with hb_report. Thanks for catching this.

I think so. Replacing/updating an object should be atomic and not expand
to delete + recreate. Naively, I have no idea how much effort this will
take to fix though.

That's an interesting separate request, maybe you can file an
enhancement bugzilla for this?

It's probably possible right now using something (untested) like

export CIB_file=/tmp/output.xml
crm configure load ...


But a "crm configure expand" or some such might be useful to have as
well.
