Best Practices for configuration management with cn=config?

I'm using puppet for configuration management and with the slapd.conf it was dumb simple to push configs to the master and the slave servers and have the server reload when the config was updated.

However I'm running an overlay that pukes with a slapd.conf and had to convert over to cn=config. Now I'm not sure how I want to manage this. Can I safely modify the files while slapd is running? I wouldn't expect it to pick up the config changes without a reload, but if I want puppet to push configs and reload will this be a valid method?

Or do I need to do something with an LDIF of the config and have some kind of ldapadd/ldapmodify mojo?

Are there any puppet modules for cn=config that I missed when I looked?
