I haven’t found any good information on which distro to use for the NAS I am building. Sure, there are a few out there. But as far as I can tell, none are immutable and that seems to be the new thing for long term durability.
Edit: One requirement is it will run a media server with hardware transcoding. I’m not quite sure if I can containerize jellyfin and still easily hardware transcode without a more expensive processor that supports hyper-v.
If you’re running unstable system packages, immutability won’t really save your stability.
So don’t complicate it, and just use Debian with nix and home-manager. That way you have a stable base, and you can create a list of bleeding edge packages that should be installed. In any case it should be essentially only docker + whatever can’t be dockerised.
