     It was my understanding that if you don't pay for support on Redhat,
you also don't get automatic updates or even manual updates.  In other
words, yum and up2date don't work.  Or is there some place you can go to get
automated updates without paying Redhat a lot of money?

     I realize that if you are controlling a few of your own servers and
have access to them around the clock, you can probably read the patch list
and install the patches yourself.  However, when you have servers located at
customer locations that might not even be turned on in the evenings or
weekends, it turns out to be cheaper for them to pay the annual Redhat fees
and get the patches much more easily than the do-it-yourself method.
