In GRASS 6:
With the g.mapset module.
To create a new mapset, it is enough to create a new directory in the
current location directory and copy across a WIND file. Maybe the VAR
file too (and perhaps 'mkdir dbf') if you have a custom database setup.

No. Shell level enviro vars have no effect on modern GRASS (5.4 and 6);
GIS vars must be set, e.g. with g.gisenv or g.mapset.
as always, maps in the PERMANENT mapset are world readable; maps in
other mapsets can be accessed by using map_name at mapset_name or by adding
to the mapset search path with g.mapsets (with an 's').
