It does. What concerns me is the sign “up to 2TB”. And I don’t understand if it is a limitation of preinstalled os or hardware.

This is really good, do you know if I can plug my 4tb m2 ssd in there? If yes, I’m moving tomorrow😁

From your list, I would go with Debian. Fedora is amazing but doesn’t have LTS, so you’ll need to update it manually quite often. You can use a script for automatic updates, but I rarely had it working smoothly. Ubuntu is just a joke with repository hell. I wouldn’t recommend it to anyone but grandma or a child for the desktop, because of its simplicity. TrueNAS never tried…🤷

I would also look into Alpine and some Arch-based distros.

And yes, use containers, this will save you time eventually.

The only real requirement you have for the Jellyfin server is ffmpeg… But this thing runs everywhere
