There have been several other threads on this, but nothing really helped me. I think it should be possible, but I am not sure and I surely don’t know how.
I’m running Rasbian Stretch on my Pi3 and I want to mount a network drive in its share folder. The network drive is a drive that I have attached to my FritzBox.
Can’t be done. Drives needs to be mounted in /mnt, mounting in /usr/share/hassio/homeassistant will not work. If your server runs nfs, you can mount in /mnt and create a symbolic link, but if your server runs samba even with Minshall+French it will be difficult (symbolic links to files work, symbolic links to folders not)
