 ### How to allow the Nextcloud container to access directories on the host?
 By default, the Nextcloud container is confined and cannot access directories on the host OS. You might want to change this when you are planning to use local external storage in Nextcloud to store some files outside the data directory and can do so by adding the environmental variable `NEXTCLOUD_MOUNT` to the docker run command of the mastercontainer (but before the last line `ghcr.io/nextcloud-releases/all-in-one:latest`! If it was started already, you will need to stop the mastercontainer, remove it (no data will be lost) and recreate it using the docker run command that you initially used). Allowed values for that variable are strings that start with `/` and are not equal to `/`.
