Try this sequence:
	r.in.tiff
	g.region rast=the_name_of_your_new_raster_layer
	d.erase
	d.rast the_name_of_your_new_raster_layer

All of the GRASS imagery commands work just fine off of disk, as UNIX 
tape drive names are just device paths also. When you are asked for the 
name of your tape drive, just give the directory path and file name of 
the file you wish to import.
