Rake not silent when told...

I am currently writing a rake task. Inside the rake task I do a sytem
call to rake db:schema:load. I tried adding the --quiet and even
--silent options and no matter what I put, I get the output of
db:schema:load. Is there a way to say no output in your rake task?

The guy I work with found this while googling...

ActiveRecord::Migration.verbose = false

That does not work either though.

Thanks in advance.
