Having not used proxmox, I'm surprised that this is a problem that can even happen at all
Is there no official tool to help people with this? I usually do my self-hosting through my NAS and it has an official program to detect NAS from that brand on the LAN

It's also not too hard to learn, I still don't really get Linux at all but a docker-compose file is basically just instructions to an installer in plaintext form
