How to mount a USB Thumb Drive (External Storage) in HASSIO? and Add-Ons?

Installation Home Assistant OS

That’s true!
For the new system hassOS instead of resinOS and this config.json example I get only a “Permission denied” when I try to mount sda1.

I added:

     "full_access": true

to the config.json instead of “privileged” and disabled the “Protection mode” in the AddOn Hass.io settings. Now I could mount the drive! But all drives are now visible in the AddOn.
Maybe someone has a better solution for that?
