keystone charm

[John Meinel]

It seems like you would tend to use:
import os

os.makedirs(os.path.dirname(config_file))

Which doesn't treat a directory that already exists as a failure.
However, I'm guessing that there is some other expectation that the
directory should be created at some other time.
