That's a problem of running logind standalone. The systemd log infrastructure uses the kernel ring buffer only during early boot. As soon as the journal is available, the log messages are logged to the journal. The problem here is, that systemd-shim doesn't provide the journal functionality, so the systemd components (like logind) continue to use the kernel ring buffer (kmsg). I'm inclined to re-assign this bug to systemd-shim, as this bug is caused by running logind under systemd-shim and the shim failing to provide that logging infrastructure. In any case, merging with the existing bug report. -- Why is it that all of the instruments seeking intelligent life in the universe are pointed away from Earth?
