| Usage |
| ===== |
| |
| Do |
| $ man 8 kexec |
| for full understanding of the underlying kexec command. |
| Gentoo offers a wrapper to the bare kexec command through |
| /etc/init.d/kexec. |
| |
| Configuration |
| ------------- |
| |
| Configuration is done in /etc/conf.d/kexec, which is self-documented. |
| |
| Usage |
| ----- |
| |
| In Gentoo, kexec is invoked, i.e., the new kernel will be booted when |
| rebooting, by reboot (8) command or by pressing Ctrl+Alt+Del. |
| |
| If you want to use kexec once, just run |
| $ /etc/init.d/kexec start |
| |
| It'll reserve kexec call at reboot. Later on, you can reboot anytime, |
| letting kexec starts another (or the same) kernel. When all is done in |
| the runlevel 6 - killing processes, unmounting volumes, etc - kexec |
| starts the new kernel instead of doing the normal hardware reboot. |
| |
| If you want kexec to be run every time you reboot, add it to a runlevel: |
| $ rc-update add kexec <runlevel> |
| |
| If you want to reboot in the normal way this time, do: |
| $ touch /nokexec |
