dbus-daemon doesn't start at bootup
I'm using Ubuntu 11.10 alpha version with latest update.
Every time when I started/restarted the system, I got the error -
Failed to start message bus:The pid file "/var/run/dbus.pid" exists,if the message bus is not runing,remove this file.
If I manually deleted that pid file before restarting the system, then the system would bootup normally next time. And "ps -lef|grep daemon" showed everything's OK. Is it supposed to be removed automatically when shutting down?
