dbus.service does not recover dbus-daemon after spurious SIGTERM

Thanks Lennart, I don't know much about dbus-daemon internals :). 

Would it then make sense to configure dbus.service to trigger system reboot
right away? Somethink like:

FailureAction=reboot

But that won't catch cases when dbus-daemon would exit successfully. Hmm I didn't
figure out any simple way to achieve that.

Would you have any ideas how to handle this with systemd?
