FWIW, and if I understand correctly the problem, now when I set a new
system, a template LOCATION is created to avoid the chicken and egg
problem. This serves multiple purposes:

1) This is a simple example that can be used for a quick demo/teaching (this
is not Spearfish);

2) This holds informations to verify that the current layout of the data
matches the library (organization of the GISDATABASE in KerGIS may vary
from version to version);

3) There is always a LOCATION/MAPSET to create other ones.

Actually, in PostgreSQL for example, you always derive a new database
from a template[12] one.

This ensures integrity and symetry of the commands (no need to handle
the special case of ab ovo).
