if your shutdown script gives the startd fair warning and tries to
gracefully shut it down (e.g. SIGTERM, not SIGQUIT or SIGKILL), the
startd will send an ad to the collector to "invalidate" itself so that
it doesn't show up in the collector anymore.  if your machines
regularly reboot to switch OS's, you should think about doing a
"condor_off" a few minutes before the scheduled reboots to give condor
a chance to clean itself up. 

good luck,
