-	With the `mntent` entry in ``config.xml``, :command:``omv-salt deploy run fstab` script writes the appropriate line in ``/etc/fstab``. You can identify entries in ``/etc/fstab`` created by the |webui| by looking at «openmediavault» tags. It is important to mention to not alter the information in between these tags. If you delete or modify a fstab option (`noexec` or `quota` for example) the next time you mount a new disk into the server, :command:`omv-salt deploy run fstab` will deploy the original value there again. If you need persistent change use :doc:`environmental variables </various/fs_env_vars>`. Finally the backend will proceed to mount the filesystem. After this the volume is ready for creating shared folders.
