By default it will take no action, and the system will keep running unless a package installation/upgrade requires a system reboot (e.g. installing a new kernel) and ``package_reboot_if_required`` is true. Using this module ensures that cloud-init is entirely finished with modules that would be executed. An example to distinguish delay from timeout: If you delay 5 (5 minutes) and have a timeout of 120 (2 minutes), then the max time until shutdown will be 7 minutes, though it could be as soon as 5 minutes. Cloud-init will invoke 'shutdown +5' after the process finishes, or when 'timeout' seconds have elapsed. .. note:: With Alpine Linux any message value specified is ignored as Alpine's halt, poweroff, and reboot commands do not support broadcasting a message. �cc_power_state_changezPower State ChangezChange power statez� power_state: delay: now mode: poweroff message: Powering off timeout: 2 condition: true z� power_state: delay: 30 mode: reboot message: Rebooting machine condition: test -f /var/tmp/reboot_me � power_state)�id�name�title� description�distros� frequency�examples�activate_by_schema_keys�metac C sj z*t �� r#t�ddt| �g�\}}|�� d }t�d|�}|�d�W S t �d| �W S t y4 Y d S w )N�procstatz-c� z\d+ (\w|\.|-)+\s+(/\w.+)� z/proc/%s/cmdline) r � is_FreeBSDr �str� splitlines�re�search�group� load_file�IOError)�pid�output�_err�line�m� r' �H/usr/lib/python3/dist-packages/cloudinit/config/cc_power_state_change.py� givecmdlineU s �r) c C s� t | t�r t�d| � | S d| }z6tj| t | t� d�}|�� |j}|dkr1t�d|� W dS |dkr>t�d|� W d S t� d ||� W d S t ya } zt� d ||� W Y d }~d S d }~ww ) NzStatic Condition: %sz check_condition command (%s): )�shellr z%sexited 0. condition met.Tr z %sexited 1. condition not met.Fz*%sunexpected exit %s. do not apply change.z%sUnexpected error: %s) � isinstance�bool�LOG�debug� subprocess�Popen�list� communicate� returncode�warning� Exception)�cond�pre�proc�ret�er' r' r( �check_conditiong s* ��r; r �cfg�cloud�args�returnc C s� zt ||j�\}}}|d u rt�d� W d S W n ty2 } zt�dt|�� W Y d }~d S d }~ww |du r>t�d� d S t�� }t |�}|sOt�d� d S t tj d�} t�d|d� |�� t �t||||t|| g� d S ) Nz&no power_state provided. doing nothingz%%s Not performing power state change!Fz3Condition was false.
