Comment (by glynn):

 Replying to [ticket:2873 wenzeslaus]:

 > The `GRASS_EXECUTABLE` does not have to be set if `grass` is on the path
 or, in theory, if it is in on some standard path

 IMHO, this "solution" is yet more duct tape on top of the existing heap.
 Any real solution would start by simply deleting the GRASS startup script
 then figuring out what needs to be done to make everything still work
 without it.

 It should not be necessary to "start" GRASS.

 On Unix, GRASS modules and libraries should be installed in system
 directories. Python packages should go in Python's site-packages
 directory. Environment variables should be set in /etc/profile (or
 whatever mechanism the distribution uses, e.g. /etc/profile.d).

 On Windows, configuration settings should probably be stored in the
 registry.

 GISRC should have a system-wide default setting such as $(HOME)/.grass/rc.
 Users who never need more than one session at a time can just use that
 file always, changing the database, location or mapset with g.mapset.
