Don't work too hard at trying to find the documentation. I found it and bookmarked it. I went back about a week or two later and got 404 instead of the tip. Good thing I could read my scribbles on (beer) napkins near the computer. Easy come easy go.
The latest URL I found for their 'issue' is this:
http://www.redhat.com/support/resources/gotchas/7.2/
Give it a try to prove to those around you you're not panicing or losing you mind ( I have seen a DEC once admit it lost its sanity).
