Hello thanks for your answer so for docker i know i can change the config path and i did it but for example i have installed plex and plex install a lot of thing in /var/lib so its in my os drive i would like to change that but i don't know how.
I use the plex plugin not plex on docker
i have a 16GB usb drive but i want to use it only for the system but the plugin plex is using all the storage space
