But when I rightly grasp to systemd sources, then 'journal-to-kmsg' mean 1) in log opening time it tries open journal and then kmsg channel; last what succeed will be taken as log target (weird?) 2) in write to log time, when record to journal should be done and it fail, then channel to kmsg is opened and report is recorded to kernel message buffer. But as according to 1) in 'normal' circumstances with 'journal-to-kmsg' is opened only kmsg channel, this behavior is tricky. Either I not uderstand this correctly, or there is something broken - maybe systemd TODO file contain notice 'journal-or-kmsg is currently broken? See ...'. Maybe systemd maintainers at some time describe these options and their behavior, IMO for now there is essential fix other, more important things.
