This argument is ignored if ``reboot=False``. See :py:func:`~salt.modules.system.reboot` for more details on this argument. CLI Example: .. code-block:: bash salt '*' kernelpkg.upgrade salt '*' kernelpkg.upgrade reboot=True at_time=1 .. note:: An immediate reboot often shuts down the system before the minion has a chance to return, resulting in errors. A minimal delay (1 minute) is useful to ensure the result is delivered to the master. z pkg.installz{}-{})�name)Zupgradesr r( Zreboot_requestedZreboot_requiredz&Rebooting system due to kernel upgradez system.reboot)�at_time) r r r r+ r. r r( �logZwarning)Zrebootr0 r% Z _needs_reboot�retr r r �upgrade� s r3 c C s t t� �t t� �kS )z� Detect if a new kernel version is available in the repositories.
