    Our system with this version is very stable, I'm afraid it would cause some problems if we release rootfs with the newest systemd. However, I will test with the newest one.

 From this boot chart, dbus.service starts after systemd-logind.service, but dbus.service takes littile time for launching.
 
 I wonder if dbus-daemon doesn't get ready for process messages even though dbus.service enter started state...
