coldreboot - Force a cold reboot bypassing kexec-tools default

/sbin/coldreboot

[reboot options]

coldreboot is a script that forces a cold reboot regardless of whether kexec is enabled or not in /etc/default/kexec

coldreboot takes the same arguments as /sbin/reboot and passes them on to /sbin/reboot later.

coldreboot prevents a kexec kernel from being loaded automatically and thus forces a cold reboot. If the user loads a kexec kernel by hand,

coldreboot will still result in a kexec reboot.
