I added a regression to the file resource. This was caused by two
different bugs that I added when I switched the API to use checkapply. I
would have caught these issues, except my test cases *also* had a bug! I
think I've fixed all three issues now.
Lastly, when running on travis, the tests behave very differently! Some
of the tests actually fail, and it's not clear why. As a result, we had
to disable them! I guess you get what you pay for.
We need to use sudo: required, and dist: trusty to avoid old versions of
bash in travis which don't support the -n argument to the `wait` shell
built-in.
We had to disable the -e checks in etcd.sh since the killall || killall
parts were causing those to trigger in travis.
