It is like a reboot 101 but it is independent of the system firmware. And like a reboot 102 you can start any kernel with it, not just Linux. 103 104 The name comes from the similarity to the exec system call. 105 106 It is an ongoing process to be certain the hardware in a machine 107 is properly shutdown, so do not be surprised if this code does not 108 initially work for you.
