Search for portable Jellyfin media server projects. It looks like there’s a few out there.

If you’re going to use this in a car, it needs to be as simple as plugging in a single device and powering it on. An over-engineered solution is going to quickly turn into a headache.

You do. It automatically reboots after applying rpm-ostree updates.

You’re right and I’m not saying that I recommend settling it to permissive. You should understand the risks involved.

I’ve been using Fedora CoreOS as my main server in my home lab for a couple years now and have been very happy with it. You still get the convenience of automatic atomic updates and you also have the flexibility of being able to install whatever additional Fedora packages you need with rpm-ostree.

I installed Docker Engine and docker-compose from upstream. You should be able to set SELinux to permissive mode if you need to so it doesn’t enforce any policies.

That’s just crazy talk. Crack some skulls and get Half-Life 2 out the door Mr. Newell. Everyone knows that you buy boxed PC games at the mall like normal people.

I would recommend Bazzite. It’s based off of Fedora Silverblue and it’s what I currently use. Very stable compared to the others that I’ve tried. Choose “Bazzite Deck” when you install if you want it to boot directly into Steam game mode.

There’s also ChimeraOS and Nobara Deck edition.

There’s Headscale if you want to avoid the Tailscale cloud service.
