Please add kexec-reboot functionality

I'm running Proxmox on a Dell PowerEdge server that takes several minutes to reboot. It's horrible, but I've found that using works AMAZINGLY well!!!

I don't know the "proper" way to install it, but apt installed the kexec-tools and Ruby from Debian and then git cloned the repo above into ~/src and then symlinked that script to ~/bin and also symlinked reboot to it for my user. Now I rebooting takes just 30-45 seconds versus several minutes.

This feature would be invaluable for everyone since Proxmox so frequently runs on server hardware.
Ehh ... doesn't this already work in Debian for many years .... and yes it did. I just tried it and it does not work anymore. Fortunately, everything is already in place (as you wrote), but it is a problem with the kexec-tools. I found this forum entry describing the exact problem:

If you just load the kernel manually, it works like it should be:

root@pve6 ~ > kexec --load /boot/vmlinuz-5.0.18-1-pve --initrd /boot/initrd.img-5.0.18-1-pve --reuse-cmdline

Next would be to test if Debian Buster is also not working and if so, we should get kexec-tools fixed upstream so that it just works.
