Sounds like writer has builders syndrome.

>There is a deeper philosophical difference too. Systems like Proxmox or TrueNAS are designed as appliances. You aren’t supposed to run arbitrary commands on the host; installing packages or tweaking config files is discouraged because you might break the middleware or lose changes on upgrade. You are effectively locked out of your own hardware’s full potential. With NixOS, the host is fully mine. I can mess with it—installing Kodi, tweaking network drivers, running local LLMs—without fear. Because the state is declarative, it is 100% obvious and reproducible. I can break the host configuration and recover to a working state in seconds, even if the machine is running essential services."

Total nonsense. The project advises caution about modifying the host because you might conflict with their package versions or lose changes on upgrade, but that's not being "locked out," that's just a maintenance consideration. The entire point of Proxmox is that you spin up VMs and containers where you do whatever you please with full isolation which is arguably more flexible than running everything on bare metal NixOS, not less.

The whole article is a guy who replaced a working hypervisor with a more complicated stack that does the same thing, had AI write it for him, and wrote a blog post about how superior it is.
