Detect machine also needs to be updated as both Orion and Hercules now have /apps/other. Suggest changing

gfs-utils/ush/detect_machine.sh

Lines 76 to 83 in 6df304f

	elif [[ -d /work ]]; then
	# We are on MSU Orion or Hercules
	if [[ -d /apps/other ]]; then
	# We are on Hercules
	MACHINE_ID=hercules
	else
	MACHINE_ID=orion
	fi

to the same as the GSI:

 elif [[ -d /work ]]; then 
  mount=$(findmnt -n -o SOURCE /home)
  if [[ ${mount} =~ "hercules" ]]; then
    MACHINE_ID=hercules
  else
    MACHINE_ID=orion
  fi
