Set default DeviceTimeout to 5.0, otherwise boot fails
The patch was added to Ubuntu by Dimitri John Ledkov when Ubuntu updated to 0.9.3 with that comment
' - Add a patch to unconditionally set DeviceTimeout to a non-zero value to prevent plymouthd asserts on boot.'
There is no details on the assert nor bug report reference that I can see. The default value in the config is non null but maybe it can be an issue for users who have a configuration file not including that key?
