> so I cannot rip DVDs, I cannot capture streams

Would any government job with a serious enough mission to require polygraphs and security clearances actually care about this kind of kindergarten illegality.

Seems like the digital equivalent of jaywalking or rolling a stop sign. Are they also going to check up and make sure you have never burned a CD in your life, or shared a Netflix password?

vs having a host OS and running docker [containers and VMs]

I think this ^ is precisely what Proxmox is, its just purpose built for this purpose and has a lot of nice features and conveniences for this use case.

Proxmox is a host OS (customized Debian) built for virtualization (KVM/Qemu) and containers (LXC containers).

​

but it seems like I could get everything it does with a well-managed host OS + ZFS/btrfs and using virtualization tools

I think you can. It just depends whether you’d prefer to DIY it yourself or whether you’d like a purpose built solution that is already pre-configured for the task, both approaches are valid and can achieve much the same outcome. The nice thing about proxmox is its mostly ready to go and well configured out of the box (with the exception of not supporting encryption ootb)

Supposedly the latest driver (545) is meant to address many of the common frustrations/issues with Nvidia + Wayland.

Compared to Intel:

1. The driver is open source
2. The driver is built in to the kernel
3. Because of this, your GPU should just work, with no manual setup or troubleshooting on your part.
4. The company (AMD) has a better/more collaborative working relationship with the Linux community than Nvidia (which has a notoriously bad reputation in the Linux community).

You can have a decent experience with Nvidia on Linux, and AMD is not perfect either, but on average more people report more frustrations, instability, and bugginess with Nvidia on Linux than AMD or Intel.

The way I would describe my experience with Nvidia + Linux is unpredictable and unreliable/inconsistent. Its not that its horrible, its just that day to day, month to month, upgrade to upgrade, distro to distro, system to system, I can’t count on things to work. Usually they do, and when they don’t usually bugs are closer to frustrations than fatal bugs, but every time I upgrade or change distro I have to worry about the GPU.

Probably a used enterprise HP/Lenovo/Dell mini or sff pc (e.g. Hp Elitedesk or Lenovo thinkcentre). The 7th gen Intel CPU’s would be the sweet spot between price and streaming performance I think. They can be had for $50-80.
