As for food functionality it is very comparable to software remote control of a computer. There are 3 key features that stand out:

• It does not rely on the target machine being booted into the OS. This means you can access it even if it crashes or locks up.
• It can “push” the power button on the machine. This requires an accessory that plugs into the motherboard. So you can force a machine off or cold boot a system.
• You can mount a boot ISO. This is like having a bootable flash drive in the target machine so you can install an OS remotely.

Edit: Because this is essentially full access to the machine as if you where physically at it, it should be considered a security risk. Not saying that you need to be scared of it, but you should be aware of the risk and protect it from unauthorized access.

My perspective. I don’t think anyone has done anything wrong in this situation. You are clearly upset because you are worried about your friend. You are upset because the other person does not feel the concerned for your friend the way you are. That response is understandable, but not rational. Humans be like that.

I think the idea of leaving your family celebration early to spend some time with your friend is a reasonable solution. Nobody gets everything, but nobody is left out.

I understand that my view point is lacking in years of nuance for the situation and could be totally off. I leave you to judge how accurate/useful my perspective is.

I’m inclined to treat the body with what I would call “professionalism”. You are not emotionally attached beyond the desire to do your job well. Though I am not opposed to some people getting a burial at sea. The better for them to be forgotten.

Many times the best way to respond to strong emotions is to just sit with it. Sit and do nothing but experience it. Don’t try to “solve the problem”, don’t shove it down.

Proxmox is basically a VM management software that runs in a Debian install. You may be able to add it to your current install, but I am not certain about that.
