Been usingthe same setup for years as well and Im happy with it, never had any issues with it

Wireguard VPN to my fritzbox lets me access my jellyfin.

Honestly just in ~/Music and stuff I’d like to listen to on the go gets copied onto my phone.

My current setup works perfectly fine, haven’t bricked my system in half a decade.
The learning curve seems steep. It seems to introduce a lot of complexity without much benefit for me. Docs are sparse and everything that is already out there is written with “traditional” setups in mind.
