  1583. kexec is a system call that implements the ability to shutdown your
  1584. current kernel, and to start another kernel. It is like a reboot
  1585. but it is independent of the system firmware. And like a reboot
  1586. you can start any kernel with it, not just Linux.
  1587. The name comes from the similarity to the exec system call.
  1588. It is an ongoing process to be certain the hardware in a machine
  1589. is properly shutdown, so do not be surprised if this code does not
  1590. initially work for you. It may help to enable device hotplugging
  1591. support. As of this writing the exact hardware interface is

  1601. the process as file descriptors supporting the read/write
  1602. syscalls, it's possible to isolate those applications in
  1603. their own address space using seccomp. Once seccomp is
  1604. enabled via /proc/<pid>/seccomp, it cannot be disabled
  1605. and the task is only allowed to execute a few safe syscalls
