      start on mounted MOUNTPOINT=/ and mounted MOUNTPOINT=/run and stopped bms-network_config
    2. Run the following command to configure the OpenStack source:

      dpkg-reconf igure cloud-init

      Run the vim /etc/cloud/cloud.cfg.d/90_dpkg.cfg command to open the configuration file and check the configuration items.

      # to update this file, run dpkg-reconf igure cloud-init
      datasource_list: [ OpenStack ]
