Absolutely but it is not easy. It needs to have several layers of abstraction by hiding what packages are being updated and auto approving themselves without prompting for password. There should be an automatic rollback mechanism in place in case an update goes bad. Some programs will need to auto-update themselves as users would expect like google chrome, firefox — which I don’t think we currently have other than steam. Otherwise if a person skips an update, they will leave their system vulnerable to the security bugs in browsers.
