Tests written?

No.

I can add test logic to the module if you think that's appropriate. I would need to add test logic to the module to bypass the normal behavior, so I'm not sure that would be a meaningful test.

The default and jenkins/PR/salt-pr-linode-ubuntu14-n tests failed, but it looks like that's just because of an apt mutex issue:

Unable to locate package python-plist=ERROR: E: Could not get lock /var/lib/apt/lists/lock - open (11: Resource temporarily unavailable)
