Renaming a GRASS location is with regard to where attribute tables are
stored similar to copying the whole GRASS database to a different
location, as frequently done when downloading GRASS sample databases
and extracting them to a location (=path) of your choice. You don't
have to reconnect the attribute tables, it works out of the box. This
is also true when renaming GRASS locations (unless you manually have
set attribute table connections to an absolute path and not to (for
dbf) $GISDBASE/$LOCATION_NAME/$MAPSET/dbf/. The environment variables
$GISDBASE $LOCATION_NAME $MAPSET are retrieved every time an attribute
table is accessed. The reason is that GRASS location renaming, GRASS
database renaming, or GRASS database copying to a different path
should not break the attribute table connections.
