Hi All,

Is it an expected behaviour that r.null doesn't affect vrt raster linked
via r.external?
Tested on forest map 2000 available for download from
I build the mosaic with gdalbuildvrt and then use r.external
then I want to set to null the values 0,2,3:
r.null mosaic setnull=0-2-3
this command doesn't have any effect on the map.
