It’s been ages since I did IT. If I had a user who wanted to run Linux then I knew that, on average, they were going to cause me a lot less headaches with random user issues so I wouldn’t mind being flexible. Endpoint security will be different, but a lot of network security is handled through network devices that don’t care what the client is.
pihole, wireguard, qbittorrent, sonarr/radarr, Jellyfin, syncthing, NFS.
I've considered Airsonic but I haven't found a good client that looks good and doesn't behave weirdly. I had one launch about 500 threads trying to transcode the same song which ate up my CPU time on my server resulting in a stern e-mailing from my host.
