Maybe the author has a specific use case, but this seems completely silly. If you want to choose which OS to boot remotely, why not ssh in the machine and change Grub's boot order for next boot with grub-reboot? Make the default boot be a minimal OS exposing ssh. You could even have the ssh server in initramfs with dropbeard / tinyssh, no need to fully boot an OS.

Because it's there. People install Doom on home appliances. This is less silly than a lot of shenanigans folks get up to.

I would set a default. That's why Grub has timers.

What in the hell is this? 🤣
