When I restart a particular computer there is an error message,

```
 # init 6
 Error getting authority: Error initializing authority: Could not connect: Connection refused (g-io-error-quark, 39)

```

I found out that this is caused by the `dbus` service. I can cause the error message to appear by

```
 # systemctl stop dbus.service
 Error getting authority: Error initializing authority: Could not connect: Connection refused (g-io-error-quark, 39)

```

This was all done in a root shell, naturally.

**Does anyone know what this means, and how to fix it?** I find that `d-bus` seems to be little documented (or too complicated for me, or both).

The machine is running CentOS Linux release 7.2.1511 and is up to date.
