But why would you want to enable the automated (and uncontrolled) update of packages? This goes against any good practice in Change Management, whose purpose is to safeguard the well-running state of a Production system. Any change brought into the Production system should have been thoroughly tested in a Quality Assurance or Test environment, which replicates the Production system, but whose failure would not be an issue. Only after you confirmed that an update will not interfere in any way with the OS and the applications running on it, only then should that update be applied in Prod. Otherwise you assume all risks for an update to crash your site or even the server completely. And to apply those automatically, so you don't even see which packages will be installed? I see that you like to live dangerously.
