One interesting change is the license.  5.4 and 5.5 Installation Guides
are released under "Creative Commons Attribution - Share Alike" which
appears to grant us the ability to edit it to replace the Redhat logos
with CentOS and to remove the references to RHN as long as we attribute
Redhat and provide a link to the original docs.
