@mike Its kinda vague but I think its designed to eliminate reboots by checking and applying important updates to the running kernel in real-time. I find I still need to update my other sw separately (e.g. using apt), and sometimes that might require reboot anyway. Don't quote me on this, but I also heard somewhere that the login is used to ensure one user is not running livepatch on more than 3 PCs or servers, as that would mean you need to pay for a commercial license.
