 Hi,

 if you use the processing (sextante) toolbox in QGIS it overwrites the
 ~/.grassrc6 file with its own temporary location settings in
 /tmp/processing.

  - this breaks the ipython demos which expect the .rc file to be in its
 unmolested state
  - this makes extra work for standalone grass users who have to click
 around to re-find their projects
  - the toolbox should use mkdtemp() or similar for health and safety
 reasons
  - don't mess with other programs' settings, it's rude

 The toolbox can and should take care of its own GISRC file, through
 environment variable settings and a temporary copy or clone, and it will
 never need to touch the user's real copy. See GRASS 6's Init.sh script
 which does just this, and the live disc's "gisvm/bin/install_grass7.sh"
 script's 'preconfig setup' for a sample, it only needs to be a 3 line text
 file.


 cheers,
 Hamish
