I am asking the question on the English forum, but I would think some German speakers also wonder about this.
In the ancient sidux days, before systemd, we were trained to change to init level 3 to run dist-upgrades. Since systemd was adopted, until this latest version 240-1, it was still possible to stop sddm, isolate the multi-user.target, and run full-upgrade with no user processes running. Today with the new systemd version 240-1, it appears that there is no longer any quick way to shut down the user processes. Whether the user logs out or not, there are multiple user processes running after a user login session.
Question: Does it matter any more? Is full-upgrade safe with user processes running?
Thank you.
