Sorry ommit the force, I always forget that force is implied by rf
since I rarely use rf, so it should be
`FileUtils.rm_rf(Dir[Rails.root.join("spec/fixtures", "**/alpha")],
secure: true)`. I use r in production (and on development I trigger a
force but with constraints) because I like exceptions to be raised so
I know exactly what's going on in my filesystem but not all people
care about that
