Support a lower end configuration
There are some customers who have decided to use RHEL because of its up to 7 year support cycle for security fixes, and industry support.
But who also don't have the option to upgrade a possibly large number of older systems along with OS upgrades.
For instance, our next software version has to be supported through 2016, while RHEL 5 is only supported standard through 2014.
This is causing us a big issue right now, since RHEL 6 doesn't support some versions of the Pentium M processor. Yet still supports even older Pentium II and III CPUs.
