...and if you want to completely disable automatic insertion of opsys 
and arch on a given submit machine, you can make Gregs requirements 
above the default by placing the following line in the condor_config 
file(s) on the machine(s) where you run condor_submit:

  APPEND_REQUIREMENTS = target.opsys =!= "" && target.arch =!= ""
