123      Network Configuration Prepared for Safe Transition
124
125      What was configured:
126        - NetworkManager installed and configured
127        - Transition script prepared: /usr/local/bin/ha-network-transition.sh
128
129      IMPORTANT: Network changes will take effect AFTER REBOOT
130        - Current SSH connection remains safe
131        - NetworkManager will take over after reboot
132        - Old networking service will be disabled after reboot
133        - Transition script will self-remove after successful run
134
135      Transition log will be available at: /var/log/ha-network-transition.log
136  when: networkmanager_config is changed
