This directory does not exist on this system.

This system has nslcd but I think it only has RAM cache and I guess that a cache on persistent storage would be needed.

System users are all local in /etc/passwd.

This system is minimal and uses plain old /etc/network/interfaces

Thanks for this solution!  I tried it and after a limited number of boots I have not seen the problem again.  Since boots are non deterministic it is not a perfect test, and I'll let you know if I see the error messages again.

How about suggesting this solution in /usr/share/doc/dbus/README.Debian?
