If you even know which line of random bullshit you changed that made it work, that is

I had a few Raspberry Pis and some Libre Computer boards a while back, but I recently decided to just build a beefy small form factor PC and put Proxmox on it, and honestly couldn’t be happier with the results. The ability to allocate resources for services and containers on the fly is a game changer. I can spin up a fresh container running whatever service I want in a matter of minutes without the hassle of flashing to a device and setting up networking, etc.

Any specific reason why you’d like to move away from Fedora? It’s an amazing distro, all things considered.
