[opensuse-virtual] Best Practices / Details for Serial Console debug-level logging when using Xen + systemd ?
I boot Opensuse 12.3 + Xen 4.3 using Grub1.

Reading

http://en.opensuse.org/SDB:Systemd#Getting_debug_from_systemd

There's a note to

ln -s /usr/lib/systemd/system/serial-getty@.service
/etc/systemd/system/getty.target.wants/serial-getty@ttyS0.service

On my system, I have just:

find /usr/lib/systemd/system/ -name *serial-getty*
/usr/lib/systemd/system/serial-getty@.service

i.e., I do NOT have the symlink for startup in place. I currently have
serial console(s) enabled using the config below. It seems to work, but
it's evolved to this over time, tweaked as kernel- and xen-versions have
changed. I suspect it needs some clean up.

My goal is to have grub, early boot, Xen and detailed, debug-level,
complete boot logged to both a serial console & video out. What, if
anything, SHOULD be changed in the config below for correctness?
Specifically, what's recommended for getting the 'right info' form boot
process for informative reporting on bugs?

cat /boot/grub/menu.lst
...
serial --unit=0 --speed=57600 --word=8 --parity=no --stop=1
terminal --timeout=6 serial console
