The only reason for importing nova.config now is where one of the options defined in that file is needed. Rather than importing nova.config using an import statement, use CONF.import_opt() so that it is clear which option we actually require. In future, we will move many options out of nova.config so many of these import_opt() calls will either go away or cause a module other than nova.config to be imported.

"""Starter script for all nova services.

|
|
This script attempts to start all the nova services in one process. Each
|
|
service is started in its own greenthread. Please note that exceptions and
|
|
sys.exit() on the starting of a service are logged and the script will
|
|
continue attempting to launch the rest of the services.
