I have been considering just installing Debian on a small PC then the jellyfin media player application set to auto start. I can think of a few different ways to get this done maybe with a couple user accounts.
I like the idea of being able to change the application that automatically starts. Maybe I want to try Kodi again. I would just change the startup app.
Get your firewall right then maybe add fail2ban.
You could also consider IDs/IPs on your primary router/firewall if this is internal. If not you can install surricata on a public server. Obviously if you go with something as powerful as surricata you no longer need fail2ban.
Keep a sharp eye on any users with sudo. Beyond that consider docker as others have mentioned.
It does add to security because it allows the developers a bit more control of what packages are utilized for their applications. It creates a more predictable environment.
It seems that way but it performs better than zfs on top of zfs. The only os I ran into that with was opnsense when I was playing with a virtualized firewall.
Within guests these days I just use XFS, UFS, or NTFS depending on the os. The hypervisor can have zfs or ceph.
I’m spoiled now. I prefer ubiquiti equipment for my network, security camera, and even door access.
However, if you prefer completely open source I can recommend opnsense and openwrt. Personally I prefer a single point of configuration… So all ubiquiti for me… It makes it easy to restore a complete network configuration as you are discovering is a pain.
Maybe start with the new cloud gateway max as a router if you are interested.
Music playlists are different from Plex. You can create them import them or generate an instant list.
4k is seamless and performs better imo. You can use transcoding or not if you have files they way you want them. If you do you can select on a per user basis who gets to transcode.
You can set bandwidth limits.
I’ve seen a feature to allow multi user streaming the same movie so you ig watch at the same time. I use npm and often a couple peeps might watch a movie at the same time without using this feature and works fine
I use the client app on Android and a firestick atm. I think I just downloaded it but you can side load too if you want. The media server app is available for various os. So technically you could set it up on whatever you want. Just check your app store

It can plug into homebrew or m3u playlists for live tv if that is your suggestion. It has a plugin for nextpvr and tvheadend if you utilize those for over the air or already have an m3u setup too in those pvr services. Those are great btw and available in docker containers.
It always defaulted to what I have my files encoded. It absolutely can transcode to support other clients and you decide preferences. I did notice since most of my files are h.264 with few h265 sometimes it helped to turn off transcoding for me because the client supported it natively. Jellyfin was transcoding h265 mkv to like an MP4. Anyway a quirk
Login is pretty simple. Passwords users can change. Has codes it can generate to approve a new device if you are already logged into an app on your phone. Like 6 temp numbers. Can also setup pins or whatever they call them under users.
That’s what I said. Cow on top of cow is bad. Pretty sure ext4 isn’t on option on opnsense. UFS or zfs. Which is the only reason I mentioned it at all when presented with that choice.
