Hello, I know that Arch is not for the "average user" and some background knowledge is expected, but this was the first time I needed a boot stick since I think at least one year. Some minutes ago I did a regular system update and after that decided to reboot. After reboot I was unable to log into my system. After fiddling a bit I rebooted to an Arch boot stick to find the following message in pacman.log: [2020-08-19T20:42:55+0200] [ALPM] warning: /etc/pam.d/system-login installed as /etc/pam.d/system-login.pacnew As this seemed to be a candidate that may cause login problems, I deleted "system-login" and moved the ".pacnew" into place. After reboot I'm now able to log in again... IMHO something like this should not happen... Maybe it's worth a note on the Arch homepage that it is important to move this pacnew into place before reboot? Manuel
