A race condition during Jenkins startup could result in the wrong order of execution of commands during initialization.

On Jenkins 2.81 and newer, including LTS 2.89.1, this could in rare cases (we estimate less than 20% of new instances) result in failure to initialize the setup wizard on the first startup.

There is a very short window of time after startup during which Jenkins may no longer show the
