I know I’m not answering your question, but for what it’s worth, I’ve run TrueNAS Scale and HAOS as VM’s on Proxmox for years without issue. I prefer to let my storage be storage and run a dedicated hypervisor.
If you’re connecting drives to TrueNAS via a HBA card then virtualising TrueNAS in Proxmox is straightforward, just pass the whole card through to the VM and TrueNAS is none the wiser. The added overhead for Proxmox is (almost) negligible.
Spin up a dedicated VM for HAOS, or whatever flavour OS you like and use docker.
Once dynamic pricing is ultimately accepted as the norm, what is the lowest price? Also, if you have the ability to instantly correct pricing “mistakes”, then you never have to stop selling the product. There’s no penalty for gouging people until someone notices, and you can instantly revert to a known tolerable price and start over.
If dynamic pricing is legal, and accepted by the consumer, whether as frequent expected pricing fluctuations, or the worst case scenario of personalised pricing, these protections may well be unenforceable.
