It was unnecessary, just name the map "MASK".

g.copy yourmask,MASK
  or
r.mapcalc MASK=yourmask

and g.remove it when done.

r.mapcalc MASK=yourmask

Note that the original r.mask created a reclass map, which uses
substantially less disk space as it doesn't copy the raster data.

Interesting, I did not know that.
