Doing a bit of digging, amending routes/middleware.py (line 92 onwards) 
with:

         if self.log_debug:
             urlinfo = "%s %s" % (environ['REQUEST_METHOD'], 
environ['PATH_INFO'])
             if 'databases' in urlinfo:
                 log.debug("Route table\n %s", self.mapper.__str__())

and comparing between the resulting devstack and packaged tables (see 
attached) makes it plain that I'm missing the database routes. I'm going 
to hunt around and try to see where these are being set (and why they 
are not more to the point). If anyone happens to know this stuff well, 
please chime in and save me :-)

regards
