2189 | kexec is a system call that implements the ability to shutdown your |
2190 | current kernel, and to start another kernel. It is like a reboot |
2191 | but it is independent of the system firmware. And like a reboot |
2192 | you can start any kernel with it, not just Linux. |
2193 | |
2194 | The name comes from the similarity to the exec system call. |
2195 | |
2196 | It is an ongoing process to be certain the hardware in a machine |
2197 | is properly shutdown, so do not be surprised if this code does not |
2198 | initially work for you. It may help to enable device hotplugging |

2207 | This kernel feature is useful for number crunching applications |

2210 | the process as file descriptors supporting the read/write |
2211 | syscalls, it's possible to isolate those applications in |
2212 | their own address space using seccomp. Once seccomp is |
2213 | enabled via /proc/<pid>/seccomp, it cannot be disabled |
2214 | and the task is only allowed to execute a few safe syscalls |
