 Replying to [comment:2 vincent]:
 > Yes, I've come to the same observation so far, but I don't know enough
 about how GRASS parses projection info to gdal; sorry for this rather
 naive question but in the case of GTiff driver why then is there no need
 to worry about coordinate reference system information for it to work?

 From what I can see the driver doesn't handle adding a new entry in the
 spatial_ref_sys table if there's no AUTHORITY node, such as in your use
 From what I can see, it also probably doesn't properly support creating
 entries in spatial_ref_sys with Spatialite 4 layout (the driver has been
 likely developped during Spatialite 3 era)
 It is "intentional" in the meaning that this wasn't implemented, but could
 potentially be added. Could be worth a ticket in Trac.

 No, the workaround is the one you found. Make sure a EPSG code is attached
 the input dataset, or assign it explictly

 I think this ticket can be closed; but I'll open another one for the last
 issue mentioned above.
