It is like a reboot 106 but it is independent of the system firmware. And like a reboot 107 you can start any kernel with it, not just Linux. 108 109 The name comes from the similarity to the exec system call. 110 111 It is an ongoing process to be certain the hardware in a machine 112 is properly shutdown, so do not be surprised if this code does not 113 initially work for you.
