thanks!

Now this is throwing on my test file: java.lang.ClassNotFoundException: unt.core.DerefableState@41d70dc4

after running this function:

(defn test-start-db []
  (-> (mount/only #{Config db/Database})
      (mount/swap {Config (read-config "config.test.yml")})
      start))

So I just found out that even if I swap the contents of the Config state, the Database state will still use the default state of Config.
