Can you also remove this block please?

DIRAC/src/DIRAC/WorkloadManagementSystem/Agent/PushJobAgent.py

Lines 574 to 580 in 8d7e680

	# -----------------------------------------------------------------------------------------------
	# Temporary hack: in v9.0, the DIRAC/Setup is meant to be removed from the configuration
	# Until then, we need to set it manually
	cfg = CFG().loadFromFile(cfgFilename)
	cfg.setOption("DIRAC/Setup", gConfig.getOption("DIRAC/Setup", "")["Value"])
	cfg.writeToFile(cfgFilename)
	# -----------------------------------------------------------------------------------------------

Thanks

I tested this in https://github.com/fstagni/Pilot/actions/runs/12118277471

I think it is fine to merge...
