--- fixes: - | apache mod_wsgi does not support passing commandline arguments to the wsgi application that it hosts. As a result when the nova api or metadata api where run under mod_wsgi it was not possible to use multiple config files or non-default file names i.e. nova-api.conf This has been addressed by the intoduction of a new, optional, environment variable ``OS_NOVA_CONFIG_FILES``. ``OS_NOVA_CONFIG_FILES`` is a ``;`` separated list of file path relitive to ``OS_NOVA_CONFIG_DIR``. When unset the default ``api-paste.ini`` and ``nova.conf`` will be used form ``/etc/nova``. This is supported for the nova api and nova metadata wsgi applications.
