     * The "mobile" module has two jobs, the partition job and the users job.
     * If we added both of them in Config::createJobs(), Calamares would run
     * them right after each other. But we need the "unpackfs" module to run
     * inbetween, that's why as workaround, the partition job is started here.
     * To solve this properly, we would need to place the partition job in an
     * own module and pass everything via globalstorage. But then we might as
     * well refactor everything so we can unify the mobile's partition job with
     * the proper partition job from Calamares. */
