That depends on whether you think you'll ever want to have a job that
won't be able to detect its own prerequisites and might just do something
harmful if started without its prerequisites instead of exiting with an
error. But agreed, that's probably relatively rare, and upstart *does*
offer a way to represent that via a pre-start shell condition.
