Correct.

BTW, this was the very first change I made to GRASS (bug #229, March
2001). Before that, r.reclass would just fail if you didn't have write
permission on the source mapset.

src/libes/gis/reclass.c, line 261:

        G_warning (_("Unable to create dependency file in [%s in %s]"),
    	    buf2, reclass->mapset);

Feel free to change it; although I'm not sure that any message will be
helpful to a user that doesn't understand the details of the reclass
mechanism. Maybe the situation should be silently ignored?
