A notify relationship sets up a resource chain, just as a requires does. A resource with a notify attribute will always be managed before its notify target and a resource with a requires attribute will always be managed after its require target. > 2.

Puppet will restart the sshd on its next run even if you've changed the config file locally. Prior to restarting the service, though, Puppet will have undone your local edits. -- Peter M.
