      Acceptance criteria

      1. Set up an evergreen instance, it is at UL-X
      2. publish a (broken) update level (example: adding a plugin without a required dependency) => instance upgrades to UL-X
      3. after restart, evergreen client detects Jenkins cannot restart, and rolls back to UL-X.
      4. Jenkins is accessible again
      5. a correct UL is published, Jenkins can upgrade to it
