why is configuration.default_value = value

[Darren Shepherd]

Completely random, but I was just reading through SQL and stumbled upon 
schema-420to430.sql and noticed

UPDATE `cloud`.`configuration` SET `default_value` = `value`;
Seems bad to just set the default value as what was currently set at 
that time.  If we want defaults, should probably go through the arduous 
process of setting the proper default values one by one.  Or, maybe 
simpler, run a fresh install and dump the values and put them in the SQL 
script as updates.
