[GRASSLIST:4931] overwriting a raster layer with g.rename

[Thomas Dewez]

Dear all,

I am puzzled by the behaviour of g.rename. The Note in the man pages say:

"However, g.rename will allow the user to overwrite other existing files in the current 
mapset by making the new file name that of an already existing file."

I used this property in the following sequence:

map1 produced by some function
map2 produced by some other function

r.patch input=map1,map2 output=map3;
g.rename rast=map3,map2;

Instead of working smoothly I get the answer:
<map2> already exists in mapset <blah>

Is there a particular command switch to overwrite the file?

Thanks for hints or ways around?

Thomas
