Note

If the contents of your /etc/redhat-release file have been changed from the default, your Red Hat Enterprise Linux installation may not be found when attempting an upgrade to Red Hat Enterprise Linux 5.0.0.

You can relax some of the checks against this file by booting with the following boot command:

linux upgradeany
