Recently I have been messing with spacewalk at work and at home. Here is a link to what it is :
Here

It really is a cool tool, so after messing with it with CentOS 6u6 clients, I realized CentOS really does not offer Errata. So I found a guy, Steve that wrote a REALLY amazing script that does all of this for you. So what I’ve done is made a small script that checks if anything has been changed with :

wget -N URL

And if it has the script will auto download the new file and extract it, as well with chmod it to 755. Finally it will check for new XML files from here for CentOS Errata and here  for redhat OVAL. Then the script will update your spacewalk server with all the errata updates 🙂
