The larsoft has ifdhc v2_3_8 that has a bug. The experiment needs to use ifdhc v2_3_9 in order to run the program. We try to setup ifdhc v2_3_9 in the job_setup section of the cfg. However, the larsoft requires unsetup before one can setup the newer version of ifdhc, So we need to have unsetup command because ups does not have a setup command can unsetup. UPS has only unsetup command to unset up.
