to change to sqlite system-wide, you'd have to edit include/dbmi.h
#define DB_DEFAULT_DRIVER "dbf"
#define DB_DEFAULT_DRIVER "sqlite"
then 'make distclean' and rebuild grass from source code.
It remains as dbf for backwards-compatibility reasons, but
I suppose something could be added to allow that constant to
be overridden if a certain environment or g.gisenv variable
To change the default db within the current mapset of course is
simply done with 'db.connect' or by writing a little script to
change/replace the mapset's VAR file.
