Map Defaults
------------

   A location beginning with a dash `-' is used to specify default
values for subsequent locations.  Any previously specified defaults in
the location-list are discarded.  The default string can be empty in
which case no defaults apply.

   The location `-fs:=/mnt;opts:=ro' would set the local mount point to
`/mnt' and cause mounts to be read-only by default.  Defaults specified
this way are appended to, and so override, any global map defaults
given with `/defaults').
