Usually the autodefer helpers in lib.sh are expected to be run in context where success is the expected outcome. However when using them for feature detection, failure can legitimately occur. But the failed command still schedules a cleanup, which will likely fail again. Instead, only schedule deferred cleanup when the positive command succeeds. This way of organizing the cleanup has the added benefit that now the return code from these functions reflects whether the command passed.
