https://bugzilla.novell.com/show_bug.cgi?id=786714 https://bugzilla.novell.com/show_bug.cgi?id=786714#c0 Summary: systemd documentation issue: serial console Classification: openSUSE Product: openSUSE Factory Version: 12.3 Milestone 0 Platform: Other OS/Version: Other Status: NEW Severity: Normal Priority: P5 - None Component: Basesystem AssignedTo: aj@suse.com ReportedBy: ro@suse.com QAContact: qa-bugs@suse.de Found By: --- Blocker: --- as we just talked about it: up to now I still have not seen a machine/VM running with systemd that has a serial console properly set up, so it's either incredibly hard or not documented in a way that people do it ... sysvinit case: - you do it for the bootloader and probably in the same file for the kernel commandline - you probably adapt etc/sysconfig/bootloader to match the above - you modify inittab to properly set the serial console getty - you configure etc/securetty adding ttyS0 (or xvc0 in xen) to allow root login on the serial console which steps are needed in a factory (or future sles12 environment) ? -- 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.

This config does also start the "sulogin" for maintenance mode on _both_ consoles so that getting the system to boot is possible from VGA and serial console. -- 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 logic is at http://cgit.freedesktop.org/systemd/systemd/tree/src/getty-generator/getty-g... - if you want to start "non standard" (ie not getty) on a specific console, you should create a file in /etc/systemd/system/, named the same way the autogenerated one (which is stored in /run/systemd/generator ), so something like /etc/systemd/system/serial-getty@ttyS0.service where you would start sulogin (you might want to look at /lib/systemd/system/rescue.service as an example). -- 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.
