I've ditched Manjaro on my RockPro and flashed the emmc with Armbian, and haven't looked back since. I added a 4tb drive and set it up with NFS, then mounted the share to my desktop and my Debian server running Jellyfin, allowing me to transfer media between them, and giving me a nice extra chunk of storage space. Besides that, I grabbed and configured UFW and Fail2Ban for some extra security. That's pretty much it, just a simple project but effective for what it is.
