I'm looking for a way to predict before upgrading, which daemons are going to get a restart. I have a few updates lined up that upgrade some core libraries and daemons and it makes sense to me that if - for instance - libpam-systemd is upgraded, that all daemons using PAM get a restart/reload.
So to be clear: I'm not looking for the packages that get updated - I'm looking for the services/daemons that get a restart or reload issued from post install tasks triggered by a given upgrade.
