I wouldn't think otherwise too. In GRASS GIS 6.4.x you have to go this path
along (v.to.rast, r.mask, r.mapcalc). In GRASS GIS 7, however, you can mask
from a vector directly (i.e. r.mask vector=SomeVectorMap).
Ensure to have set the resolution of the region to the one you desire as an
output. Most of the times it should match the resolution of the raster map(s)
to be masked. Otherwise, a resampling (based on Nearest Neighbour) will take
