1833	  kexec is a system call that implements the ability to shutdown your
1834	  current kernel, and to start another kernel.  It is like a reboot
1835	  but it is independent of the system firmware.   And like a reboot
1836	  you can start any kernel with it, not just Linux.
1837
1838	  The name comes from the similarity to the exec system call.
1839
1840	  It is an ongoing process to be certain the hardware in a machine
1841	  is properly shutdown, so do not be surprised if this code does not
1842	  initially work for you.  It may help to enable device hotplugging
1843	  support.  As of this writing the exact hardware interface is

1854	  the process as file descriptors supporting the read/write
1855	  syscalls, it's possible to isolate those applications in
1856	  their own address space using seccomp. Once seccomp is
1857	  enabled via /proc/<pid>/seccomp, it cannot be disabled
1858	  and the task is only allowed to execute a few safe syscalls
