- Someone deletes his dbus job file.
- dbus-daemon fails to start (misconfiguration, whatever)
- upstart would be usable without the complete dbus package (it would
only have to depend on libdbus)

It's more of a gut feeling, that relying on the system bus for these
core tools, makes upstart more fragile and error prone.
