I also have a side question, how do you stop the duct system? I don't see any halt in my version of duct/core (`0.6.3`)
duct 0.6.x is quite old. What's your duct/lein-duct version?
typically you use integrant.repl/halt (and go, reset etc)
but I'm not sure your version of duct uses that
I highly recommend upgrading asap https://github.com/duct-framework/duct/blob/master/UPGRADING.md
