It seems I’m being sucked into the Proxmox rat hole. Spent some time researching installation, use cases and etc. Then concluded having a second machine to set it up on would be better (keep current services alive during transition). Which of course led me to decide I should replace my tiny & barely fast enough BMAX with a more modern fanless model and so on.
Oh what fun we’ll have. Next to find out how to create a VM from the existing Linux Mint on the BMAX.
