Editing the condor_config is the only way to make the changes permanent. 
 Anything you change using condor_config_val is going to revert each 
time you restart the daemons.  You shouldn't have to restart the 
computers, though.  A "condor_reconfig [machine]" or for some settings, 
a "condor_restart [machine]" should suffice.  That way you won't 
interrupt any non-Condor activity on the machines in question.
