In between I tried the debugging shell. On tty9 I get the shell, but no matter which command I try (mount, ps, ..) I do not get any results and the command seems to hang. I can even type nonesense like fff and get no error but again the "command" hangs. I can interrupt it by Ctrl-C and get a new shell prompt. The system is still active, eg I can change ttys the system reacts to magig sysreq key press. I disabled the autofs init-script and then tried to start up and reboot like before. This time it worked each time I tried. Next I tried to reenable autofs, reboot, then manually stopped the service (systemctl stop autofs) and then reboot. Again the system hangs but this time I still have a remote ssh open and it was not killed so I could run journalctl to get the log: http://userpages.uni-koblenz.de/~krienke/tmp/systemd/journalctl What is striking to me is that the logs shows: May 14 09:28:27 rzinstal3 systemd[1]: Unit autofs.service entered failed state This was exactly the time I manually stopped autofs, which worked. One existing NFS automount was umounted and no auto* process is now running any longer. I'll leave the system in that state (a working shell still open) if someone has an idea how to find out more about this problem.
