It is like a reboot 102 but it is independent of the system firmware. And like a reboot 103 you can start any kernel with it, not just Linux. 104 105 The name comes from the similarity to the exec system call. 106 107 It is an ongoing process to be certain the hardware in a machine 108 is properly shutdown, so do not be surprised if this code does not 109 initially work for you.
