we read BackupAddr Defunct option, see SlurmctldHost. BackupController Defunct option, see SlurmctldHost. ... ControlAddr Defunct option, see SlurmctldHost. ControlMachine Defunct option, see SlurmctldHost. but what does "Defunct" actually mean there? A top-ranked internet search result suggests that it means "no longer existing or functioning." but if that's the case, then if, say, your only defintion of a "ControlMachine" in your 20.02's slurm.conf was in the defunct ControlMachine parameter, how would your Slurm instance know what name the "ControlMachine" had ?
