List of paths that should be mounted before this one. This filesystem's
<option>device</option> and <option>mountPoint</option> are always
checked and do not need to be included explicitly. If a path is added

the path will be mounted before this filesystem. The paths do not need
to actually be the <option>mountPoint</option> of some other filesystem.
