Hmm, I can't seem to confirm the issue in a test case. How is your solution
working without importing `env`? - Also, should I import `env` from slave?
- I tried setting the two `env`s to equal, but it still prompted me for
host (yes, env.hosts is definitely set when it reaches slave)

from os import environ
from fabric.api import execute, env
from slave import funtimes
env.key_filename = environ['PRIVATE_QUAY_PATH']
env.hosts = ['ec2-{omitted}.compute.amazonaws.com']
env.user = 'ubuntu'
execute(funtimes)
*slave/__init__.py*
#!/usr/bin/env python
from fabric.api import run
def funtimes():
run('echo Hello funtimes')
