Yeah I’ve been recommending Arch based did for a while. Personally I’m on void and Alpine, but as a first distro things like Cachy and Endeavour are unrivalled.

Yeah if it’s just for Plex something like Endeavour OS would be pretty much painless.

Definitely easier than fighting a key.

Honestly, Switch to a basic Linux distro and use docker directly.

I ran TrueNAS for a while and it’s just too complex and janky. I dropped back to void (for ZFS) and have a directory of compose files for radar/sonar, jellyfish, mediawiki, Lemmy etc.
