def test_can_generate_prefixes_if_allowed_and_available():
"""
This is actually kinda fiddly: we may generate timezone keys with the
"posix/" or "right/" prefix if-and-only-if they are present on the filesystem.
This immediately rules out Windows (which uses the tzdata package instead),
along with OSX (which doesn't seem to have prefixed keys). We believe that
they are present on at least most Linux distros, but have not done exhaustive
testing.
It's fine to just patch this test out if it fails - passing in the
Hypothesis CI demonstrates that the feature works on *some* systems.
