SOLVED: Libraries

Ah. Its ext4. Good. I had assumed it was NTFS or something. We can just remove the ACL instead and use basic linux permissions.

Code:

sudo setfacl -b -R /media/littlebox
sudo chmod 755 /media/littlebox
sudo find "/media/littlebox/Big Box 2" -type d -exec chmod 755 {} \;
sudo find "/media/littlebox/Big Box 2" -type f -exec chmod 644 {} \;

This SHOULD set the permissions open enough for Jellyfin to read everything in Big Box 2.
