I came across ryot a while ago but didn’t have a chance to really play with it. It might be useful for something like this though. Grocy is another that comes to mind.

Can you elaborate?

No, the OS that would be running Tailscale or Wireguard. If the OS doesn’t boot, those remote access options don’t work, which is where a KVM comes in handy, rather than having to hook up a monitor and keyboard.

Unless it doesn’t boot.
