The pre-2.1 yum included the option to the update command to download 
updates but not install them. This eliminates the need to wait for them to 
download once I've blessed them. I'd use that option in the midnight cron 
job, then apply the updates in the morning. If all went well, I'd not waste 
time waiting for the download, and if there was an issue, users wouldn't 
have to wait for me to get in to fix it.
