It is like a reboot 96 but it is independent of the system firmware. And like a reboot 97 you can start any kernel with it, not just Linux. 98 99 The name comes from the similarity to the exec system call. 100 101 It is an ongoing process to be certain the hardware in a machine 102 is properly shutdown, so do not be surprised if this code does not 103 initially work for you.
