Unfortunately, the documentation does not apply anymore as, as you've told me, systemd does not respect /etc/inittab. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

The thing that SEEMS to work is to specify console=ttyS0 ONLY. The agetty parameters are wrong then, but at least I can log in. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

Like I said, for me only console=ttyS0 works, as soon as console=tty0 is mentioned, there is no getty started. However since I need special getty settings, I guess I will just go with your suggestion and create my own service. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
