That can be before or after sending SIGHUP it doesn't matter. > BTW, I am not using openstack. Sorry for the confusion. My mistake sorry, I saw talk about VMs and assumed openstack. I'd be interested to hear more about the system you are working on, on or off list. If you need to have configuration deleted automatically when the file is deleted using inotify, I can look at doing that. It's significant extra complexity, so it makes sense to determine if it's needed first.
