Novell ZENworks 10 Configuration Management
If a bundle deployment contains a "Reboot now" action, it contains a set time to wait to reboot. If the user does click to the cancel reboot action, the User Cancel dialog goes away after that time, but it still reboots also.
This is fixed in version 10.0.3 - see TID 3486285 "Updates to ZENworks 10 Configuration Management" which can be found at https://www.novell.com/support .
There is a need for the User to Cancel a reboot Action. But leave the message up forever. Then, when the user says yes reboot it will cause the reboot.
