 If cfgmgr is not running, then b10-auth may hang waiting for some response
 and can't serve DNS. Not being able to serve DNS is fine, but maybe
 b10-auth should complain if can't communicate to configuration manager.

 So sitting here:

 }}}

 msgq does log:
 {{{

 '4bf2d0f9_4 at t1.m.reedmedia.net', 'type': 'send'}
 }}}

 (Yes I know b10-cfgmgr is not running.)
